*What? A heated bed optimized for low energy consumption: Differential heating could allow localized heating of the heated bed for small prints.
*How? Through the use of small size heating elements distributed across the whole area of the heated bed and the use of materials with low heat conductivity.
*Why? While prototyping small parts or producing small quantities of small parts there are large areas of the heated bed that are not in use but which still get heated.

Is it possible? Likely. 
Is it useful? Yes, as far as energy consumption is significantly reduced. Aim? 30% reduction. 

=General description of the concept=
A main plate made of a material with low heat conductivity (ceramic, glass-ceramic [https://www.schott.com/d/nextrema/2a9bf3b3-b75a-48b1-ab89-2684bb872c34/20190402121615/brochure-schott-nextrema-en_02042019.pdf]
) with a thickness of around about 3mm. The plate could be a standalone plate or could be fitted or manufactured with a lattice for rigidity if necessary. Small individually controlled heating elements are fitted (glued, painted) on the underside. The heated elements can be painted using conductive graphite ink directly on the bed material or on small mica squares or hexagons [https://dateccoating.com/heating-elements-mica/] that could later be attached to the bed.

=Challenges=
#Low cost, locally sourced and produced bed material. (Can I bake my own ceramic bed and grind it flat?)
#Ink adhesion and incorporation of terminals for soldering of wires.
#Pattern and thickness of deposited ink to achieve optimal efficiency.

*Conductive carbon/graphite ink: graphite powder in a matrix of water glass (sodium silicate / Natriumsilikat) or ZnBr2 [https://www.youtube.com/c/cayrex2/search?query=ink]

cayrex2 in YouTube commen: To simplify this is,.... you add 20,5 grams of NaBr2 into 100 ml of water and 28,7 grams of ZnSO24 (heptahydrate) in 100 ml of water. But if you use ZnSO4 anhydrous then you need 16.1 grams for 100 ml of water. Another way to get a ZnBr2 is if you make with copper (II)bromide solution and metalic zinc, but CuBr2 can be expensive, so stick to first method. When you make a solution of NaBr2 and ZnSO4 then you need to heat the solution so long that the Na2SO4 start form a cristals on the bottom (from 200ml to boild down to about 75 - 50 ml) and for the finish you put the hot solution in cold water and you wait that the solution will be cooled down. On the bottom you will see cristals of Na2SO4 and the solution will be ZnBr2 + H2O

==Sun Feb 11, 2018==

*Printed the first set of short idler side parts for the D3D printer. Prints are aesthetically acceptable and the dimensions are accurate. 
*Worked on D3D Australia log.
See [[D3D Australia]] for more details. 
3 Hours

==Fri Feb 09, 2018==

*Printed a few more test models. Prints are of acceptable quality. Dimensions are accurate. Some more refining can be achieved.
*I had to reinstall Cura LulzBot Edition but only managed to find Version 2.6.66 which has a different interface to the version I had become familiar with, although it offers a wider variety of options to tweak the prints.
*Solved issues with squashed bottom layers.
*There is a fair bit of shadow/ripple/ghosting on the printed pieces that need to be reduced. 
See [[D3D Australia]] for more details. 
6 Hours

==Tue Feb 06, 2018==

*Finished geometry rearrangement on D3D printer.
*Printed test models.
*Worked on resolving some issues. 
See [[D3D Australia]] for more details. 
5 Hours

==Sun Feb 04, 2018==

*Worked on [[D3D Australia]] log. 
2 Hours

==Fri Feb 02, 2018==

*3d printer assembly. Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for D3D 3D printer.

I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established. 
6 Hours

==Tue Jan 30, 2018==

*Test printing. Changed the steps per millimeter configuration on the z-axis.
*Printed a quick fix to add mechanical strength to the HBP support and keep the sandwich closed tight around the rods.
See [[D3D Australia]] 
4 Hours

==Wed Jan 24, 2018==

*First day of test-printing and the machine performs very well considering where we come from. A few details need attention to improve the quality of the prints.
*Solved yesterday's issue with three-point probing. For some reason, the GCode in Cura had changed.
*Worked on D3D Australia log.
See [[D3D Australia]] 
6 Hours

==Tue Jan 23, 2018==

*Worked on Marlin firmware values for probing points, travel limits after homing and extruder offset. I struggled to find a physical reference to match with what the values in the firmware where indication. The imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left. See details on [[D3D Australia]] 
6 Hours

==Mon Jan 22, 2018==

*Worked on Marlin firmware. Half-succeeded at getting the Z-probe to stay within the boundaries of the HBP.
*Set the machine to print a cube in mid-air, without filament. It worked twice, then I had issues that I believe are related to the firmware. I must have accidentally changed something.
*Worked on D3D Australia log and the Troubleshooting section of the Product Manual where I added a table.

*Troubleshooting yesterday's problems. All day.
**Issues getting the motors to move. After exchanging some emails with Roberto and Marcin, and a fair bit of googling, some of these problems where solved. A couple of things remain unresolved. Heating of HBP is one of them. Relay module is on standby but there seems to be an issue with the activation signal from RAMPS.
*Worked on D3D Australia.
Working on the [http://opensourceecology.org/wiki/D3D_1612_Product_Manual#Troubleshooting Troubleshooting] section of the Product Manual page.

*Finished design and printed alternative to cable chain.
*Finished routing wires.
*Watched Devs meeting video from Tuesday, Jan 9.
*Worked on uploading Marlin firmware to Arduino and tried to set up the printer. Issues arose:
**X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
**There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 0.2mm, it actually moves like 5 whole millimeters instead.
**The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time.

Followed guidelines from [http://opensourceecology.org/wiki/D3D_1612_Product_Testing Product Testing] in this wiki. 
6 Hours

==Wed Jan 17, 2018==

*Routing wires in the machine.
*Design of alternative to cable chain for X-axis wiring
*Read about connections on RAMPS and Arduino.
*Visited some local shops searching for a missing heatsink for one of the Pololu drivers. Purchased 1.5 meters of plastic spiral wrap. 
6 Hours

==Fri Jan 12, 2018==

*Glued heated bed to the holder and attached it to the carriage on the Z-axis.
*Routed HBP power wires to relay module and PSU.
*Wired and installed relay module.
*Designed and printed insulating box for relay module.
*Edited D3D Australia log. 
5 Hours

==Tue Jan 09, 2018==
*Glued rubber spacers to HBP.
*Glued PEI film to HBP.
*Glued magnets to PSU and intalled it on the frame.
*Studied details concerning the wiring
*Started the design of an insulating box for the relay moduke. 
5 Hours

==Mon Jan 08, 2018==
*Cut heat-resistant rubber to use as a spacer between heated bed and bed rods.
*Rearranged end stops to shorten the length of travel on Y and lengthen it on X.
*Installed step motor controllers on RAMPS board.
*Adjusted X-axis so it is parallel to frame. 
3 Hours

==Sat Jan 06, 2018==
*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector.
*Installed sensor holder on extruder.
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area's size and position.
*Worked on D3D Australia Log 
4 Hours

==Wed Jan 03, 2018==
*Trimmed 2mm from M6x30 SS screws.
*Generated .stl and .gcode files and printed belt pegs.
*Finished the assembly and attached X and Y axes to frame.
Belt tensioning mechanism works great. 

''Issues to resolve''
*With the current configuration, the X axis has a total travel of 191mm (7 1/2 in). Moving the end stop further towards Y2 on the X axis could increase this travel by 12mm (1/2 in).
*At the moment, the Z-axis sits 20mm offset towards Y2 in relation to the center of travel of the carriage on the X-axis' (center of bed on X). 
3 Hours

==Tue Jan 02, 218==
*Affixed stepper motors to axes assemblies.
*Bought the twelve M6x30mm screws that needed to affix the axes to the frame and attached the Z-axis.
*Looked for references on the orientation of the motor terminals. I will go with the Y-axes diagonally down and back, X-axis and Z-axis diagonally up and left (towards Y1).
*Cut belts lengths.
I think that the instructions for the assembly of the axes can be made simpler in writing. Also, I need to work on a checklist for each step of the assembly. 
3 Hours

==Mon Jan 01, 2018==
*Worked on the wiring of the controller. Changed the sequence of the wires on a PHR-4 terminal and soldered the wires of the Dupont connector from the extra end stop to the inductive sensor's wires. Connected the cables for all the axes, end stops, Z probe and extruder motor to the controller,
*Looked for details on setting up the relay module for the HBP.
*Worked on D3D Australia Log.
===Some doubts===
Tried to figure out some details about the wiring of the relay to feed power to the HBP.
After a few hours of watching videos and reading some specifications about relays and MOSFETs, this is part of what I believe is correct:
#What I have is a 2 channel relay module, which is not the same than a MOSFET.
#I will split the positive wire going to the HBP and connect it to one of the relays. Let's say relay 1. I will connect one of the split ends of the wire to the NO1 position and the other one to the COM1. This means that while the coil of the relay is not energized, there will be no power going to the HBP.
#I will connect a pair of wires carrying 12V, coming directly from the PSU, to the DC+ and DC- terminals of the relay module.

'''Questions are:'''
*Where am I getting the signal to activate the relay from? I believe that I have to connect whatever single wire coming in from somewhere to the IN1 terminal of the module. Is that one wire coming from one of the terminals on the D8 position of the controller? Is it the + or - wire? And,
*Do I need to reset the jumpers on S1 and S2. At the moment the configuration is High-Com for both.
*On the extruder motor, the PHR-6 connector: Is the color sequence of the wires the same than for the rest of the stepper motors?

==Tue Dec 19, 2017==

The 3D printed parts with the brim are pretty much perfect. Removed brim and assembled two carriages. They slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. Used a ZAP brand clear epoxy. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. Only tack weld it at this point.

Short Iddler Side printed successfully. Created .gcode file and started printing another set of parts (Motor Side). Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). Put together some of axes parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing. br>
5 Hours

==Thu Dec 14, 2017==

First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process. Revisited some links that relate to the final assembly of the axes and printer. Looked at details for HBP holder.

More work on Australian BOM for D3D Printer. Ordering parts. I would like to test the magnets when they arrive to have a precise idea of the weight they can actually carry. Watched developers meeting from Oct 24th. 
4 Hours

==Sat Nov 04, 2017==

Looking for local vendors, Australian BOM for D3D Printer. Ordering parts. Due diligence: understanding specifications of parts to order the correct ones from alternative sources. Compromise between prices, shipping costs and shipping times. The paradox of choice. 
5 Hours

==Sun Oct 29, 2017==

As I read through the piled up information related to the D3D printer, I keep drifting away from the main objective of this twelve-weeks plan, this mainly due to the lack of knowledge on the subject. The learning process consumes most of my time at the moment. 
Embedded a copy of the August 12, 2017: RAMPS version of BOM to this log. I haven't yet made changes to it.

==Sat Oct 28, 2017==

Twelve-week D3D build plan. 
4 Hours

==Fri Oct 27, 2017==

Working on finding local vendors in Australia for the parts in the BOM. I think that many of the parts will be sourced from current vendor links since most of these parts are substantially more expensive here. 
4 Hours

==Tue Oct 24, 2017==

Kept at chasing links related to D3D printing development. List of parts, assembly, BOM, etc. Worked on a slide to outline a 12-week plan to put together a prototype here in Australia and evaluate the chances of at least gathering the parts in Argentina to build another machine over there. 
See slides under title: 3D Printer: all links. 
3 Hours

==Sun Oct 22, 2017==

Made an attempt to track all links related to D3D printing spread around OSE Wiki. I found this to be a time-consuming task, in part because I did not participate in the R&D process. Nevertheless, I believe that this information should be better organized to facilitate accessibility to all newcomers and those wanting to learn the basis of each development. This could also be related to my lack of overall familiarity with the way logs are kept. This exercise was still useful to learn several details associated to the D3D printing project. 
2 Hours

==Thu Oct 19, 2017==

Watched some more free CAD tutorials and revisited Roberto's video several times. Phone talk with Marcin. Started putting together a twelve-week plan to build the 16" 3D printer here in Australia. 
2 Hours

==Wed Oct 18, 2017==

Went through some more of the meetings and added minutes in a comment for the meeting of Wed Sep 27, 2017. Just by accident learned that YouTube automatically creates links for the time format 00:00:00 so one can create a sort of time index where different topics can be easily found within the video. This was a personal exercise in an attempt to keep track of the topics being discussed, but I think we should look at making it a standard addition to the videos. e.g.

I've been catching up with what has been going on in the past four weeks. Watched recorded meetings and have a read throughout the slides and notes.
Ran new Linux live version (0.45) on an older computer. Everything seems to be in order. Booting up takes a long time, between 6 and 6.5 minutes. 
5 Hours

==Fri Sep 08, 2017==

*Watched Aug 29 meeting video once again. Watched Sep 05 meeting video. I'm starting to find my bearings. 
Important information from meetings is easy to overlook when one is not familiar with the details of what is going on and have to deal with many new concepts and tools. 
Going to the supermarket to buy a notepad (handy for when I watch the videos on devices other than my laptop). 
Left the Sep 05 meeting video halfway through thinking that I knew where to go and that it was going to be easy to find, but encountered the same issue as I did many times before: got lost in the Wiki. It reminds me, somehow, to those neighborhoods where the streets are not straight and one ends many times in some cul de sac.
*Added a link to the Tractor Construction Set 2017 and to the Power Cube v17.08 to this log. 
*Started working on the Master CAD file for the Micro Tractor this evening. I managed to put the four holes to support the motors on the brackets but I think the large bore has to be reduced in order to have more material between the edge of the bore and the orifices for the bolts.
*Uploaded a new file for the motor brackets with the four holes to attach the motor. Not sure whether that is ok but I put it there just in case.
*I struggle with the constraint of parts in the assembly 2 workbench. I still don't know how to get one part or the other to stay in its place.
*I cannot preview my edits in the Wiki. I always have to save in order to view changes.

Encountered some troubles trying to fit the nut to the bolt. Not familiar with what ISOs are a match between the fasteners. Also, the Screw Hole Calculator says that a M30 screw should fit a hole of 26.5 mm but if I measure the M30 bolt with the ruler it says 29.91 mm approx. I do not know how to understand this discrepancy at the moment.

==Sat Aug 12, 2017==

Another long afternoon in front of the computer with FreeCAD. It has been very frustrating at times. It reminds me of the days in which I wanted to format a letter in MSWord and had no clue on how to do it. Things are intuitive, but not so.
*Learned some characteristics of the Sketcher workbench and how to toggle between workbenches to access the tools needed for differents parts of the job.
*Encountered a problem that I have not been able to solve yet. When I try to sink or stretch my sketch on the face of one of the tubes a dialog box appears saying that ''the shape is not perfect or that it's not closed'' (need to investigate). The program also freezes for a couple of minutes.

*Printed the first set of short idler side parts for the D3D printer. Prints are aesthetically acceptable and the dimensions are accurate. 
*Worked on D3D Australia log.
See [[D3D Australia]] for more details. 
3 Hours

==Fri Feb 09, 2018==

*Printed a few more test models. Prints are of acceptable quality. Dimensions are accurate. Some more refining can be achieved.
*I had to reinstall Cura LulzBot Edition but only managed to find Version 2.6.66 which has a different interface to the version I had become familiar with, although it offers a wider variety of options to tweak the prints.
*Solved issues with squashed bottom layers.
*There is a fair bit of shadow/ripple/ghosting on the printed pieces that need to be reduced. 
See [[D3D Australia]] for more details.

==Fri Feb 02, 2018==

*3d printer assembly. Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for D3D 3D printer.

I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established. 
6 Hours

==Tue Jan 30, 2018==

*Test printing. Changed the steps per millimeter configuration on the z-axis.
*Printed a quick fix to add mechanical strength to the HBP support and keep the sandwich closed tight around the rods.

4 Hours

==Wed Jan 24, 2018==

*First day of test-printing and the machine performs very well considering where we come from. A few details need attention to improve the quality of the prints.
*Solved yesterday's issue with three-point probing. For some reason, the GCode in Cura had changed.
*Worked on D3D Australia log.
See [[D3D Australia]] 
6 Hours

==Tue Jan 23, 2018==

*Worked on Marlin firmware values for probing points, travel limits after homing and extruder offset. I struggled to find a physical reference to match with what the values in the firmware where indication. The imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left. See details on [[D3D Australia]] 
6 Hours

==Mon Jan 22, 2018==

*Worked on Marlin firmware. Half-succeeded at getting the Z-probe to stay within the boundaries of the HBP.
*Set the machine to print a cube in mid-air, without filament. It worked twice, then I had issues that I believe are related to the firmware. I must have accidentally changed something.
*Worked on D3D Australia log and the Troubleshooting section of the Product Manual where I added a table.

*Finished design and printed alternative to cable chain.
*Finished routing wires.
*Watched Devs meeting video from Tuesday, Jan 9.
*Worked on uploading Marlin firmware to Arduino and tried to set up the printer. Issues arose:
**X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
**There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 0.2mm, it actually moves like 5 whole millimeters instead.
**The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time.

Followed guidelines from [http://opensourceecology.org/wiki/D3D_1612_Product_Testing Product Testing] in this wiki.

*Trimmed 2mm from M6x30 SS screws.
*Generated .stl and .gcode files and printed belt pegs.
*Finished the assembly and attached X and Y axes to frame.
Belt tensioning mechanism works great. 

''Issues to resolve''
*With the current configuration, the X axis has a total travel of 191mm (7 1/2 in). Moving the end stop further towards Y2 on the X axis could increase this travel by 12mm (1/2 in).
*At the moment, the Z-axis sits 20mm offset towards Y2 in relation to the center of travel of the carriage on the X-axis' (center of bed on X). 
3 Hours

==Tue Jan 02, 218==
*Affixed stepper motors to axes assemblies.
*Bought the twelve M6x30mm screws that needed to affix the axes to the frame and attached the Z-axis.
*Looked for references on the orientation of the motor terminals. I will go with the Y-axes diagonally down and back, X-axis and Z-axis diagonally up and left (towards Y1).
*Cut belts lengths.
I think that the instructions for the assembly of the axes can be made simpler in writing. Also, I need to work on a checklist for each step of the assembly. 
3 Hours

==Mon Jan 01, 2018==
*Worked on the wiring of the controller. Changed the sequence of the wires on a PHR-4 terminal and soldered the wires of the Dupont connector from the extra end stop to the inductive sensor's wires. Connected the cables for all the axes, end stops, Z probe and extruder motor to the controller,
*Looked for details on setting up the relay module for the HBP.
*Worked on D3D Australia Log.
===Some doubts===
Tried to figure out some details about the wiring of the relay to feed power to the HBP.
After a few hours of watching videos and reading some specifications about relays and MOSFETs, this is part of what I believe is correct:
#What I have is a 2 channel relay module, which is not the same than a MOSFET.
#I will split the positive wire going to the HBP and connect it to one of the relays. Let's say relay 1. I will connect one of the split ends of the wire to the NO1 position and the other one to the COM1. This means that while the coil of the relay is not energized, there will be no power going to the HBP.
#I will connect a pair of wires carrying 12V, coming directly from the PSU, to the DC+ and DC- terminals of the relay module.

'''Questions are:'''
*Where am I getting the signal to activate the relay from? I believe that I have to connect whatever single wire coming in from somewhere to the IN1 terminal of the module. Is that one wire coming from one of the terminals on the D8 position of the controller? Is it the + or - wire? And,
*Do I need to reset the jumpers on S1 and S2. At the moment the configuration is High-Com for both.
*On the extruder motor, the PHR-6 connector: Is the color sequence of the wires the same than for the rest of the stepper motors?

The 3D printed parts with the brim are pretty much perfect. Removed brim and assembled two carriages. They slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. Used a ZAP brand clear epoxy. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. Only tack weld it at this point.

==Fri Dec 15, 2017==

Short Iddler Side printed successfully. Created .gcode file and started printing another set of parts (Motor Side). Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). Put together some of axes parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing. br>

==Thu Dec 14, 2017==

First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process. Revisited some links that relate to the final assembly of the axes and printer. Looked at details for HBP holder.

More work on Australian BOM for D3D Printer. Ordering parts. I would like to test the magnets when they arrive to have a precise idea of the weight they can actually carry. Watched developers meeting from Oct 24th. 
4 Hours

==Sat Nov 04, 2017==

Looking for local vendors, Australian BOM for D3D Printer. Ordering parts. Due diligence: understanding specifications of parts to order the correct ones from alternative sources. Compromise between prices, shipping costs and shipping times. The paradox of choice. 
5 Hours

==Sun Oct 29, 2017==

As I read through the piled up information related to the D3D printer, I keep drifting away from the main objective of this twelve-weeks plan, this mainly due to the lack of knowledge on the subject. The learning process consumes most of my time at the moment. 
Embedded a copy of the August 12, 2017: RAMPS version of BOM to this log. I haven't yet made changes to it.

Twelve-week D3D build plan. 
4 Hours

==Fri Oct 27, 2017==

Working on finding local vendors in Australia for the parts in the BOM. I think that many of the parts will be sourced from current vendor links since most of these parts are substantially more expensive here. 
4 Hours

==Tue Oct 24, 2017==

Kept at chasing links related to D3D printing development. List of parts, assembly, BOM, etc. Worked on a slide to outline a 12-week plan to put together a prototype here in Australia and evaluate the chances of at least gathering the parts in Argentina to build another machine over there. 
See slides under title: 3D Printer: all links. 
3 Hours

==Sun Oct 22, 2017==

Made an attempt to track all links related to D3D printing spread around OSE Wiki. I found this to be a time-consuming task, in part because I did not participate in the R&D process. Nevertheless, I believe that this information should be better organized to facilitate accessibility to all newcomers and those wanting to learn the basis of each development. This could also be related to my lack of overall familiarity with the way logs are kept. This exercise was still useful to learn several details associated to the D3D printing project. 
2 Hours

==Thu Oct 19, 2017==

Watched some more free CAD tutorials and revisited Roberto's video several times. Phone talk with Marcin. Started putting together a twelve-week plan to build the 16" 3D printer here in Australia. 
2 Hours

==Wed Oct 18, 2017==

Went through some more of the meetings and added minutes in a comment for the meeting of Wed Sep 27, 2017. Just by accident learned that YouTube automatically creates links for the time format 00:00:00 so one can create a sort of time index where different topics can be easily found within the video. This was a personal exercise in an attempt to keep track of the topics being discussed, but I think we should look at making it a standard addition to the videos. e.g.

==Fri Sep 08, 2017==

*Watched Aug 29 meeting video once again. Watched Sep 05 meeting video. I'm starting to find my bearings. 
Important information from meetings is easy to overlook when one is not familiar with the details of what is going on and have to deal with many new concepts and tools. 
Going to the supermarket to buy a notepad (handy for when I watch the videos on devices other than my laptop). 
Left the Sep 05 meeting video halfway through thinking that I knew where to go and that it was going to be easy to find, but encountered the same issue as I did many times before: got lost in the Wiki. It reminds me, somehow, to those neighborhoods where the streets are not straight and one ends many times in some cul de sac.
*Added a link to the Tractor Construction Set 2017 and to the Power Cube v17.08 to this log. 
*Started working on the Master CAD file for the Micro Tractor this evening. I managed to put the four holes to support the motors on the brackets but I think the large bore has to be reduced in order to have more material between the edge of the bore and the orifices for the bolts.
*Uploaded a new file for the motor brackets with the four holes to attach the motor. Not sure whether that is ok but I put it there just in case.
*I struggle with the constraint of parts in the assembly 2 workbench. I still don't know how to get one part or the other to stay in its place.
*I cannot preview my edits in the Wiki. I always have to save in order to view changes.

Encountered some troubles trying to fit the nut to the bolt. Not familiar with what ISOs are a match between the fasteners. Also, the Screw Hole Calculator says that a M30 screw should fit a hole of 26.5 mm but if I measure the M30 bolt with the ruler it says 29.91 mm approx. I do not know how to understand this discrepancy at the moment.

==Sat Aug 12, 2017==

Another long afternoon in front of the computer with FreeCAD. It has been very frustrating at times. It reminds me of the days in which I wanted to format a letter in MSWord and had no clue on how to do it. Things are intuitive, but not so.
*Learned some characteristics of the Sketcher workbench and how to toggle between workbenches to access the tools needed for differents parts of the job.
*Encountered a problem that I have not been able to solve yet. When I try to sink or stretch my sketch on the face of one of the tubes a dialog box appears saying that ''the shape is not perfect or that it's not closed'' (need to investigate). The program also freezes for a couple of minutes.

*Printed the first set of short idler side parts for the D3D printer. Prints are aesthetically acceptable and the dimensions are accurate. 
*Worked on D3D Australia log.
See [[D3D Australia]] for more details. 
3 Hours

==Fri Feb 09, 2018==

*Printed a few more test models. Prints are of acceptable quality. Dimensions are accurate. Some more refining can be achieved.
*I had to reinstall Cura LulzBot Edition but only managed to find Version 2.6.66 which has a different interface to the version I had become familiar with, although it offers a wider variety of options to tweak the prints.
*Solved issues with squashed bottom layers.
*There is a fair bit of shadow/ripple/ghosting on the printed pieces that need to be reduced. 
See [[D3D Australia]] for more details.

==Fri Feb 02, 2018==

*3d printer assembly. Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for D3D 3D printer.

I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established. 
6 Hours

==Tue Jan 30, 2018==

*Test printing. Changed the steps per millimeter configuration on the z-axis.
*Printed a quick fix to add mechanical strength to the HBP support and keep the sandwich closed tight around the rods.

4 Hours

==Wed Jan 24, 2018==

*First day of test-printing and the machine performs very well considering where we come from. A few details need attention to improve the quality of the prints.
*Solved yesterday's issue with three-point probing. For some reason, the GCode in Cura had changed.
*Worked on D3D Australia log.
See [[D3D Australia]] 
6 Hours

==Tue Jan 23, 2018==

*Worked on Marlin firmware values for probing points, travel limits after homing and extruder offset. I struggled to find a physical reference to match with what the values in the firmware where indication. The imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left. See details on [[D3D Australia]] 
6 Hours

==Mon Jan 22, 2018==

*Worked on Marlin firmware. Half-succeeded at getting the Z-probe to stay within the boundaries of the HBP.
*Set the machine to print a cube in mid-air, without filament. It worked twice, then I had issues that I believe are related to the firmware. I must have accidentally changed something.
*Worked on D3D Australia log and the Troubleshooting section of the Product Manual where I added a table.

*Finished design and printed alternative to cable chain.
*Finished routing wires.
*Watched Devs meeting video from Tuesday, Jan 9.
*Worked on uploading Marlin firmware to Arduino and tried to set up the printer. Issues arose:
**X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
**There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 0.2mm, it actually moves like 5 whole millimeters instead.
**The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time.

Followed guidelines from [http://opensourceecology.org/wiki/D3D_1612_Product_Testing Product Testing] in this wiki.

*Trimmed 2mm from M6x30 SS screws.
*Generated .stl and .gcode files and printed belt pegs.
*Finished the assembly and attached X and Y axes to frame.
Belt tensioning mechanism works great. 

''Issues to resolve''
*With the current configuration, the X axis has a total travel of 191mm (7 1/2 in). Moving the end stop further towards Y2 on the X axis could increase this travel by 12mm (1/2 in).
*At the moment, the Z-axis sits 20mm offset towards Y2 in relation to the center of travel of the carriage on the X-axis' (center of bed on X). 
3 Hours

==Tue Jan 02, 218==
*Affixed stepper motors to axes assemblies.
*Bought the twelve M6x30mm screws that needed to affix the axes to the frame and attached the Z-axis.
*Looked for references on the orientation of the motor terminals. I will go with the Y-axes diagonally down and back, X-axis and Z-axis diagonally up and left (towards Y1).
*Cut belts lengths.
I think that the instructions for the assembly of the axes can be made simpler in writing. Also, I need to work on a checklist for each step of the assembly. 
3 Hours

==Mon Jan 01, 2018==
*Worked on the wiring of the controller. Changed the sequence of the wires on a PHR-4 terminal and soldered the wires of the Dupont connector from the extra end stop to the inductive sensor's wires. Connected the cables for all the axes, end stops, Z probe and extruder motor to the controller,
*Looked for details on setting up the relay module for the HBP.
*Worked on D3D Australia Log.
===Some doubts===
Tried to figure out some details about the wiring of the relay to feed power to the HBP.
After a few hours of watching videos and reading some specifications about relays and MOSFETs, this is part of what I believe is correct:
#What I have is a 2 channel relay module, which is not the same than a MOSFET.
#I will split the positive wire going to the HBP and connect it to one of the relays. Let's say relay 1. I will connect one of the split ends of the wire to the NO1 position and the other one to the COM1. This means that while the coil of the relay is not energized, there will be no power going to the HBP.
#I will connect a pair of wires carrying 12V, coming directly from the PSU, to the DC+ and DC- terminals of the relay module.

'''Questions are:'''
*Where am I getting the signal to activate the relay from? I believe that I have to connect whatever single wire coming in from somewhere to the IN1 terminal of the module. Is that one wire coming from one of the terminals on the D8 position of the controller? Is it the + or - wire? And,
*Do I need to reset the jumpers on S1 and S2. At the moment the configuration is High-Com for both.
*On the extruder motor, the PHR-6 connector: Is the color sequence of the wires the same than for the rest of the stepper motors? 
5 Hours

*Worked on D3D Australia log.
*Worked on the wiring of the controller. 
2 Hours

==Sat Dec 30, 2017==
*Soldered wires to HBP. This took some time since the 25-watt soldering iron that I have was not powerful enough to do the job. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from magnet and nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors.
*Worked on D3D Australia log. 
5 Hours

==Thu Dec 28, 2017==
*Modified the .stl, created .gcode and printed: sensor holder, end stop interfaces and flanges for idler bearings.
*Glued magnets to x-axis carriage and extruder motor interface.
*Worked on some ideas for the HBP. I am not going to be using a second z-axis at this stage. 
3 Hours

==Wed Dec 27, 2017==
*Drilled and redrilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*The bearings for the idlers that I received do not have flanges. I will 3D print a set of washers that will reduce the friction of the belt against the sides of the bearings' receptacle on the short idler side.
*Worked on D3D Australia log. 
4 Hours

==Tue Dec 26, 2017==

==Tue Dec 19, 2017==

The 3D printed parts with the brim are pretty much perfect. Removed brim and assembled two carriages. They slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. Used a ZAP brand clear epoxy. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. Only tack weld it at this point.

Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing. br>
5 Hours

==Thu Dec 14, 2017==

First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process. Revisited some links that relate to the final assembly of the axes and printer. Looked at details for HBP holder.

==Sat Nov 04, 2017==

Looking for local vendors, Australian BOM for D3D Printer. Ordering parts. Due diligence: understanding specifications of parts to order the correct ones from alternative sources. Compromise between prices, shipping costs and shipping times. The paradox of choice. 
5 Hours

==Sun Oct 29, 2017==

As I read through the piled up information related to the D3D printer, I keep drifting away from the main objective of this twelve-weeks plan, this mainly due to the lack of knowledge on the subject. The learning process consumes most of my time at the moment. 
Embedded a copy of the August 12, 2017: RAMPS version of BOM to this log. I haven't yet made changes to it.

==Fri Oct 27, 2017==

Working on finding local vendors in Australia for the parts in the BOM. I think that many of the parts will be sourced from current vendor links since most of these parts are substantially more expensive here. 
4 Hours

==Tue Oct 24, 2017==

Kept at chasing links related to D3D printing development. List of parts, assembly, BOM, etc. Worked on a slide to outline a 12-week plan to put together a prototype here in Australia and evaluate the chances of at least gathering the parts in Argentina to build another machine over there. 
See slides under title: 3D Printer: all links. 
3 Hours

==Sun Oct 22, 2017==

Made an attempt to track all links related to D3D printing spread around OSE Wiki. I found this to be a time-consuming task, in part because I did not participate in the R&D process. Nevertheless, I believe that this information should be better organized to facilitate accessibility to all newcomers and those wanting to learn the basis of each development. This could also be related to my lack of overall familiarity with the way logs are kept. This exercise was still useful to learn several details associated to the D3D printing project. 
2 Hours

==Thu Oct 19, 2017==

Watched some more free CAD tutorials and revisited Roberto's video several times. Phone talk with Marcin. Started putting together a twelve-week plan to build the 16" 3D printer here in Australia.

==Wed Oct 18, 2017==

Went through some more of the meetings and added minutes in a comment for the meeting of Wed Sep 27, 2017. Just by accident learned that YouTube automatically creates links for the time format 00:00:00 so one can create a sort of time index where different topics can be easily found within the video. This was a personal exercise in an attempt to keep track of the topics being discussed, but I think we should look at making it a standard addition to the videos. e.g.

*Watched Aug 29 meeting video once again. Watched Sep 05 meeting video. I'm starting to find my bearings. 
Important information from meetings is easy to overlook when one is not familiar with the details of what is going on and have to deal with many new concepts and tools. 
Going to the supermarket to buy a notepad (handy for when I watch the videos on devices other than my laptop). 
Left the Sep 05 meeting video halfway through thinking that I knew where to go and that it was going to be easy to find, but encountered the same issue as I did many times before: got lost in the Wiki. It reminds me, somehow, to those neighborhoods where the streets are not straight and one ends many times in some cul de sac.
*Added a link to the Tractor Construction Set 2017 and to the Power Cube v17.08 to this log. 
*Started working on the Master CAD file for the Micro Tractor this evening. I managed to put the four holes to support the motors on the brackets but I think the large bore has to be reduced in order to have more material between the edge of the bore and the orifices for the bolts.
*Uploaded a new file for the motor brackets with the four holes to attach the motor. Not sure whether that is ok but I put it there just in case.
*I struggle with the constraint of parts in the assembly 2 workbench. I still don't know how to get one part or the other to stay in its place.
*I cannot preview my edits in the Wiki. I always have to save in order to view changes.

Encountered some troubles trying to fit the nut to the bolt. Not familiar with what ISOs are a match between the fasteners. Also, the Screw Hole Calculator says that a M30 screw should fit a hole of 26.5 mm but if I measure the M30 bolt with the ruler it says 29.91 mm approx. I do not know how to understand this discrepancy at the moment.

==Sat Aug 12, 2017==

Another long afternoon in front of the computer with FreeCAD. It has been very frustrating at times. It reminds me of the days in which I wanted to format a letter in MSWord and had no clue on how to do it. Things are intuitive, but not so.
*Learned some characteristics of the Sketcher workbench and how to toggle between workbenches to access the tools needed for differents parts of the job.
*Encountered a problem that I have not been able to solve yet. When I try to sink or stretch my sketch on the face of one of the tubes a dialog box appears saying that ''the shape is not perfect or that it's not closed'' (need to investigate). The program also freezes for a couple of minutes.

*Printed the first set of short idler side parts for the D3D printer. Prints are aesthetically acceptable and the dimensions are accurate. 
*Worked on D3D Australia log.
See [[D3D Australia]] for more details. 
3 Hours

==Fri Feb 09, 2018==

*Printed a few more test models. Prints are of acceptable quality. Dimensions are accurate. Some more refining can be achieved.
*I had to reinstall Cura LulzBot Edition but only managed to find Version 2.6.66 which has a different interface to the version I had become familiar with, although it offers a wider variety of options to tweak the prints.
*Solved issues with squashed bottom layers.
*There is a fair bit of shadow/ripple/ghosting on the printed pieces that need to be reduced. 
See [[D3D Australia]] for more details.

*3d printer assembly. Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for D3D 3D printer.

I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

4 Hours

==Wed Jan 24, 2018==

*First day of test-printing and the machine performs very well considering where we come from. A few details need attention to improve the quality of the prints.
*Solved yesterday's issue with three-point probing. For some reason, the GCode in Cura had changed.
*Worked on D3D Australia log.
See [[D3D Australia]] 
6 Hours

==Tue Jan 23, 2018==

*Worked on Marlin firmware values for probing points, travel limits after homing and extruder offset. I struggled to find a physical reference to match with what the values in the firmware where indication. The imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left. See details on [[D3D Australia]] 
6 Hours

==Mon Jan 22, 2018==

*Worked on Marlin firmware. Half-succeeded at getting the Z-probe to stay within the boundaries of the HBP.
*Set the machine to print a cube in mid-air, without filament. It worked twice, then I had issues that I believe are related to the firmware. I must have accidentally changed something.
*Worked on D3D Australia log and the Troubleshooting section of the Product Manual where I added a table.

*Finished design and printed alternative to cable chain.
*Finished routing wires.
*Watched Devs meeting video from Tuesday, Jan 9.
*Worked on uploading Marlin firmware to Arduino and tried to set up the printer. Issues arose:
**X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
**There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 0.2mm, it actually moves like 5 whole millimeters instead.
**The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time.

Followed guidelines from [http://opensourceecology.org/wiki/D3D_1612_Product_Testing Product Testing] in this wiki.

*Finished the assembly and attached X and Y axes to frame.
Belt tensioning mechanism works great. 

''Issues to resolve''
*With the current configuration, the X axis has a total travel of 191mm (7 1/2 in). Moving the end stop further towards Y2 on the X axis could increase this travel by 12mm (1/2 in).
*At the moment, the Z-axis sits 20mm offset towards Y2 in relation to the center of travel of the carriage on the X-axis' (center of bed on X). 
3 Hours

==Tue Jan 02, 218==
*Affixed stepper motors to axes assemblies.
*Bought the twelve M6x30mm screws that needed to affix the axes to the frame and attached the Z-axis.
*Looked for references on the orientation of the motor terminals. I will go with the Y-axes diagonally down and back, X-axis and Z-axis diagonally up and left (towards Y1).
*Cut belts lengths.
I think that the instructions for the assembly of the axes can be made simpler in writing. Also, I need to work on a checklist for each step of the assembly. 
3 Hours

*Worked on D3D Australia Log.
===Some doubts===
Tried to figure out some details about the wiring of the relay to feed power to the HBP.
After a few hours of watching videos and reading some specifications about relays and MOSFETs, this is part of what I believe is correct:
#What I have is a 2 channel relay module, which is not the same than a MOSFET.
#I will split the positive wire going to the HBP and connect it to one of the relays. Let's say relay 1. I will connect one of the split ends of the wire to the NO1 position and the other one to the COM1. This means that while the coil of the relay is not energized, there will be no power going to the HBP.
#I will connect a pair of wires carrying 12V, coming directly from the PSU, to the DC+ and DC- terminals of the relay module.

'''Questions are:'''
*Where am I getting the signal to activate the relay from? I believe that I have to connect whatever single wire coming in from somewhere to the IN1 terminal of the module. Is that one wire coming from one of the terminals on the D8 position of the controller? Is it the + or - wire? And,
*Do I need to reset the jumpers on S1 and S2. At the moment the configuration is High-Com for both.
*On the extruder motor, the PHR-6 connector: Is the color sequence of the wires the same than for the rest of the stepper motors?

==Tue Dec 19, 2017==

The 3D printed parts with the brim are pretty much perfect. Removed brim and assembled two carriages. They slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. Used a ZAP brand clear epoxy. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. Only tack weld it at this point.

Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing. br>
5 Hours

==Thu Dec 14, 2017==

First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process. Revisited some links that relate to the final assembly of the axes and printer. Looked at details for HBP holder.

More work on Australian BOM for D3D Printer. Ordering parts. I would like to test the magnets when they arrive to have a precise idea of the weight they can actually carry. Watched developers meeting from Oct 24th. 
4 Hours

==Sat Nov 04, 2017==

Looking for local vendors, Australian BOM for D3D Printer. Ordering parts. Due diligence: understanding specifications of parts to order the correct ones from alternative sources. Compromise between prices, shipping costs and shipping times. The paradox of choice. 
5 Hours

==Sun Oct 29, 2017==

As I read through the piled up information related to the D3D printer, I keep drifting away from the main objective of this twelve-weeks plan, this mainly due to the lack of knowledge on the subject. The learning process consumes most of my time at the moment. 
Embedded a copy of the August 12, 2017: RAMPS version of BOM to this log. I haven't yet made changes to it. 
5 Hours

==Sat Oct 28, 2017==

Twelve-week D3D build plan. 
4 Hours

==Fri Oct 27, 2017==

Working on finding local vendors in Australia for the parts in the BOM. I think that many of the parts will be sourced from current vendor links since most of these parts are substantially more expensive here. 
4 Hours

==Tue Oct 24, 2017==

Kept at chasing links related to D3D printing development. List of parts, assembly, BOM, etc. Worked on a slide to outline a 12-week plan to put together a prototype here in Australia and evaluate the chances of at least gathering the parts in Argentina to build another machine over there. 
See slides under title: 3D Printer: all links. 
3 Hours

==Sun Oct 22, 2017==

Made an attempt to track all links related to D3D printing spread around OSE Wiki. I found this to be a time-consuming task, in part because I did not participate in the R&D process. Nevertheless, I believe that this information should be better organized to facilitate accessibility to all newcomers and those wanting to learn the basis of each development. This could also be related to my lack of overall familiarity with the way logs are kept. This exercise was still useful to learn several details associated to the D3D printing project. 
2 Hours

==Thu Oct 19, 2017==

Watched some more free CAD tutorials and revisited Roberto's video several times. Phone talk with Marcin. Started putting together a twelve-week plan to build the 16" 3D printer here in Australia. 
2 Hours

==Wed Oct 18, 2017==

Went through some more of the meetings and added minutes in a comment for the meeting of Wed Sep 27, 2017. Just by accident learned that YouTube automatically creates links for the time format 00:00:00 so one can create a sort of time index where different topics can be easily found within the video. This was a personal exercise in an attempt to keep track of the topics being discussed, but I think we should look at making it a standard addition to the videos. e.g.

==Fri Sep 08, 2017==

*Watched Aug 29 meeting video once again. Watched Sep 05 meeting video. I'm starting to find my bearings. 
Important information from meetings is easy to overlook when one is not familiar with the details of what is going on and have to deal with many new concepts and tools. 
Going to the supermarket to buy a notepad (handy for when I watch the videos on devices other than my laptop). 
Left the Sep 05 meeting video halfway through thinking that I knew where to go and that it was going to be easy to find, but encountered the same issue as I did many times before: got lost in the Wiki. It reminds me, somehow, to those neighborhoods where the streets are not straight and one ends many times in some cul de sac.
*Added a link to the Tractor Construction Set 2017 and to the Power Cube v17.08 to this log. 
*Started working on the Master CAD file for the Micro Tractor this evening. I managed to put the four holes to support the motors on the brackets but I think the large bore has to be reduced in order to have more material between the edge of the bore and the orifices for the bolts.
*Uploaded a new file for the motor brackets with the four holes to attach the motor. Not sure whether that is ok but I put it there just in case.
*I struggle with the constraint of parts in the assembly 2 workbench. I still don't know how to get one part or the other to stay in its place.
*I cannot preview my edits in the Wiki. I always have to save in order to view changes. 
5 Hours

Encountered some troubles trying to fit the nut to the bolt. Not familiar with what ISOs are a match between the fasteners. Also, the Screw Hole Calculator says that a M30 screw should fit a hole of 26.5 mm but if I measure the M30 bolt with the ruler it says 29.91 mm approx. I do not know how to understand this discrepancy at the moment.

6 Hours

==Sat Aug 12, 2017==

Another long afternoon in front of the computer with FreeCAD. It has been very frustrating at times. It reminds me of the days in which I wanted to format a letter in MSWord and had no clue on how to do it. Things are intuitive, but not so.
*Learned some characteristics of the Sketcher workbench and how to toggle between workbenches to access the tools needed for differents parts of the job.
*Encountered a problem that I have not been able to solve yet. When I try to sink or stretch my sketch on the face of one of the tubes a dialog box appears saying that ''the shape is not perfect or that it's not closed'' (need to investigate). The program also freezes for a couple of minutes.

== '''Bio''' ==
Grew up surrounded by an excellent family and great friends in a relatively healthy little corner of Argentina, but still under the societal constraints of a country with severe social unbalances, unpredictable state policies and a very volatile economy. Spent twelve years of my life subjugated to an education system that I did not like and that today I consider as being harmful to the betterment of any individual and of society as a whole. Then spent another eight years not knowing what to make out of life. Believing that things have to be different in other places, left Argentina in 2008 in an attempt to peer over the wall and catch a glimpse of what there was to see in the world. Found that I knew nothing about anything or about myself. I have spent the last nine years in an effort to catch up and am now trying to figure out whether I can be of assistance to others that are trapped in the constraints of current social paradigms, including myself. I see OSE as one way of paving the path to achieving this goal.

I am at the moment also in the very slow process of putting together a website, in the Spanish language, aimed to stimulate people to start asking themselves questions that could lead them to recognize their important role in creating an equal society, understanding that we are the product of our own making. Human nature is a very, very, very relative term and an easy excuse to keep behaving negligently with one another, the environment and the rest of the species on this planet.

==Sun Feb 11, 2018==

*Printed the first set of short idler side parts for the D3D printer. Prints are aesthetically acceptable and the dimensions are accurate. 
*Worked on D3D Australia log.
See [[D3D Australia]] for more details. 
3 Hours

==Fri Feb 09, 2018==

*Printed a few more test models. Prints are of acceptable quality. Dimensions are accurate. Some more refining can be achieved.
*I had to reinstall Cura LulzBot Edition but only managed to find Version 2.6.66 which has a different interface to the version I had become familiar with, although it offers a wider variety of options to tweak the prints.
*Solved issues with squashed bottom layers.
*There is a fair bit of shadow/ripple/ghosting on the printed pieces that need to be reduced. 
See [[D3D Australia]] for more details. 
6 Hours

==Tue Feb 06, 2018==

*Finished geometry rearrangement on D3D printer.
*Printed test models.
*Worked on resolving some issues. 
See [[D3D Australia]] for more details. 
5 Hours

==Sun Feb 04, 2018==

*Worked on [[D3D Australia]] log. 
2 Hours

==Fri Feb 02, 2018==

*3d printer assembly. Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for D3D 3D printer.

I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established. 
6 Hours

==Tue Jan 30, 2018==

*Test printing. Changed the steps per millimeter configuration on the z-axis.
*Printed a quick fix to add mechanical strength to the HBP support and keep the sandwich closed tight around the rods.
See [[D3D Australia]] 
4 Hours

==Wed Jan 24, 2018==

*First day of test-printing and the machine performs very well considering where we come from. A few details need attention to improve the quality of the prints.
*Solved yesterday's issue with three-point probing. For some reason, the GCode in Cura had changed.
*Worked on D3D Australia log.
See [[D3D Australia]] 
6 Hours

==Tue Jan 23, 2018==

*Worked on Marlin firmware values for probing points, travel limits after homing and extruder offset. I struggled to find a physical reference to match with what the values in the firmware where indication. The imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left. See details on [[D3D Australia]] 
6 Hours

==Mon Jan 22, 2018==

*Worked on Marlin firmware. Half-succeeded at getting the Z-probe to stay within the boundaries of the HBP.
*Set the machine to print a cube in mid-air, without filament. It worked twice, then I had issues that I believe are related to the firmware. I must have accidentally changed something.
*Worked on D3D Australia log and the Troubleshooting section of the Product Manual where I added a table.

*Troubleshooting yesterday's problems. All day.
**Issues getting the motors to move. After exchanging some emails with Roberto and Marcin, and a fair bit of googling, some of these problems where solved. A couple of things remain unresolved. Heating of HBP is one of them. Relay module is on standby but there seems to be an issue with the activation signal from RAMPS.
*Worked on D3D Australia.
Working on the [http://opensourceecology.org/wiki/D3D_1612_Product_Manual#Troubleshooting Troubleshooting] section of the Product Manual page.

==Thu Jan 18, 2018==

*Finished design and printed alternative to cable chain.
*Finished routing wires.
*Watched Devs meeting video from Tuesday, Jan 9.
*Worked on uploading Marlin firmware to Arduino and tried to set up the printer. Issues arose:
**X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
**There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 0.2mm, it actually moves like 5 whole millimeters instead.
**The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time.

Followed guidelines from [http://opensourceecology.org/wiki/D3D_1612_Product_Testing Product Testing] in this wiki. 
6 Hours

==Wed Jan 17, 2018==

*Routing wires in the machine.

==Wed Jan 03, 2018==
*Trimmed 2mm from M6x30 SS screws.
*Generated .stl and .gcode files and printed belt pegs.
*Finished the assembly and attached X and Y axes to frame.
Belt tensioning mechanism works great. 

''Issues to resolve''
*With the current configuration, the X axis has a total travel of 191mm (7 1/2 in). Moving the end stop further towards Y2 on the X axis could increase this travel by 12mm (1/2 in).
*At the moment, the Z-axis sits 20mm offset towards Y2 in relation to the center of travel of the carriage on the X-axis' (center of bed on X). 
3 Hours

==Tue Jan 02, 218==
*Affixed stepper motors to axes assemblies.
*Bought the twelve M6x30mm screws that needed to affix the axes to the frame and attached the Z-axis.
*Looked for references on the orientation of the motor terminals. I will go with the Y-axes diagonally down and back, X-axis and Z-axis diagonally up and left (towards Y1).
*Cut belts lengths.
I think that the instructions for the assembly of the axes can be made simpler in writing. Also, I need to work on a checklist for each step of the assembly. 
3 Hours

==Mon Jan 01, 2018==
*Worked on the wiring of the controller. Changed the sequence of the wires on a PHR-4 terminal and soldered the wires of the Dupont connector from the extra end stop to the inductive sensor's wires. Connected the cables for all the axes, end stops, Z probe and extruder motor to the controller,
*Looked for details on setting up the relay module for the HBP.
*Worked on D3D Australia Log.
===Some doubts===
Tried to figure out some details about the wiring of the relay to feed power to the HBP.
After a few hours of watching videos and reading some specifications about relays and MOSFETs, this is part of what I believe is correct:
#What I have is a 2 channel relay module, which is not the same than a MOSFET.
#I will split the positive wire going to the HBP and connect it to one of the relays. Let's say relay 1. I will connect one of the split ends of the wire to the NO1 position and the other one to the COM1. This means that while the coil of the relay is not energized, there will be no power going to the HBP.
#I will connect a pair of wires carrying 12V, coming directly from the PSU, to the DC+ and DC- terminals of the relay module.

'''Questions are:'''
*Where am I getting the signal to activate the relay from? I believe that I have to connect whatever single wire coming in from somewhere to the IN1 terminal of the module. Is that one wire coming from one of the terminals on the D8 position of the controller? Is it the + or - wire? And,
*Do I need to reset the jumpers on S1 and S2. At the moment the configuration is High-Com for both.
*On the extruder motor, the PHR-6 connector: Is the color sequence of the wires the same than for the rest of the stepper motors?

*Drilled and redrilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*The bearings for the idlers that I received do not have flanges. I will 3D print a set of washers that will reduce the friction of the belt against the sides of the bearings' receptacle on the short idler side.
*Worked on D3D Australia log.

The 3D printed parts with the brim are pretty much perfect. Removed brim and assembled two carriages. They slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. Used a ZAP brand clear epoxy. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. Only tack weld it at this point.

See slides under title: 3D Printer: all links. 
3 Hours

==Sun Oct 22, 2017==

Made an attempt to track all links related to D3D printing spread around OSE Wiki. I found this to be a time-consuming task, in part because I did not participate in the R&D process. Nevertheless, I believe that this information should be better organized to facilitate accessibility to all newcomers and those wanting to learn the basis of each development. This could also be related to my lack of overall familiarity with the way logs are kept. This exercise was still useful to learn several details associated to the D3D printing project.

Went through some more of the meetings and added minutes in a comment for the meeting of Wed Sep 27, 2017. Just by accident learned that YouTube automatically creates links for the time format 00:00:00 so one can create a sort of time index where different topics can be easily found within the video. This was a personal exercise in an attempt to keep track of the topics being discussed, but I think we should look at making it a standard addition to the videos. e.g.

Important information from meetings is easy to overlook when one is not familiar with the details of what is going on and have to deal with many new concepts and tools. 
Going to the supermarket to buy a notepad (handy for when I watch the videos on devices other than my laptop). 
Left the Sep 05 meeting video halfway through thinking that I knew where to go and that it was going to be easy to find, but encountered the same issue as I did many times before: got lost in the Wiki. It reminds me, somehow, to those neighborhoods where the streets are not straight and one ends many times in some cul de sac.
*Added a link to the Tractor Construction Set 2017 and to the Power Cube v17.08 to this log. 
*Started working on the Master CAD file for the Micro Tractor this evening. I managed to put the four holes to support the motors on the brackets but I think the large bore has to be reduced in order to have more material between the edge of the bore and the orifices for the bolts.
*Uploaded a new file for the motor brackets with the four holes to attach the motor. Not sure whether that is ok but I put it there just in case.
*I struggle with the constraint of parts in the assembly 2 workbench. I still don't know how to get one part or the other to stay in its place.

=='''Sun Feb 11, 2018'''==

===Printing===

*Printed the first set of short idler side parts for the D3D printer. Prints are aesthetically acceptable and the dimensions are accurate.

=='''Fri Feb 09, 2018'''==

===Printing===

*Printed four more cubes and one cone. Prints are of acceptable quality. Dimensions are accurate. Some more refining can be achieved.

===Troubleshooting===

* I had to reinstall Cura LulzBot Edition but only managed to find Version 2.6.66 which has a different interface to the version I had become familiar with, although it offers a wider variety of options to tweak the prints.
*I tried several different options to eliminate the issue with the squashed bottom layers. Things I tried and DID NOT work:
#Increasing voltage on stepper motors' drivers.
#Changing steps/mm configuration for the Z-axis. Increased it from 80 to 83 steps/mm. This had an effect in making the irregularities disappear from the lower parts of the prints but increased the overall height of the pice by some 10%.
#Changing computers and OS.
*What DID work:
#Changing acceleration value for Z from 100 to 1000.
#Edditing start G-Code in Cura.

===Notes===
After reinstalling Cura, I decided to go with the start G-Code already written in the software. This script only had a few lines and did not include ABL (auto bed leveling). I printed two cubes in this configuration and noticed that the squashed bottom layers had almost disappeared from the prints. I then added the ABL to the code but left the rest unchanged. Prints where good but it seems that for some reason adding ABL to the code created ripples/shadowing/ghosting in the side of the cubes.

===Issues to resolve===

*There is a fair bit of shadow/ripple/ghosting on the printed pieces.

=='''Tue Feb 06, 2018'''==

===Assembly===

*Finished geometry rearrangement. Extruder nozzle and inductive sensor holder.

===Printing===

*Printed eight test cubes with varying degree of success.

===Issues===

*Ubuntu prompted me to update some software, which I did. In the process, Cura was updated and it changed to the standard version, which was not working on my computer.
*The issue with the squashed bottom layers remain. The printed pieces show rough sides around the lower part and are shorter in height.

=='''Fri Feb 02, 2018'''==

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.
*Changed Z-axis motor in an attempt to fix the issue with the squashed bottom layers.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

=='''Tue Jan 30, 2018'''==

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. <del>But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.</del>

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above. This discrepancy is associated with the difference in the geometry of this machine compared with OSE's standard. The motor on the X-axis should be on the Y1 side.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

===Wiring===

*Routed more wires in the machine.
*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

==Assembly==

*The spacers described under "Printing" are not necessary unless you do not feel like walking to the hardware store for some washers.
*Do not use the holes-template tool described under "Printing".

===Printing===

Printed and test fitted: 
*Template to accurately place holes on metal frame.
*Set of 12 spacers to separate the bolted axes assemblies from the metal frame. Inbuild separation is 2mm.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

=='''Sat Dec 23, 2017'''==

===Assembly===

*Assembled carriages for the four axes (+- 15 min per assembly) and glued the magnets on the x-axis carriage. See notes for more details about this assembly.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

=='''Tue Dec 19, 2017'''==

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm 
Bottom/Top thickness: 1.2mm 
Fill density: 25% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 50 C 
Nozzle size: 0.4mm 
These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

=='''Sun Dec 17, 2017'''==

*Started this log.

===Printing===

Generated .gcode file for [http://opensourceecology.org/wiki/File:Universal_axis_carriage_side.stl Carriage Side] and started the printing process. Estimated printing time for one set of four parts is 11:00:00. Eight of these parts are needed (two sets with current .stl file layout). 
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.6mm 
Bottom/Top thickness: 1.5mm 
Fill density: 25% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 70 C 
Nozzle size: 0.4mm 
These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

=='''Sat Dec 16, 2017'''==

===Assembly===

*Glued the last 16in square to the frame and trimmed excess epoxy (+-1 hour). 

===Printing===

*Printed a second set of Motor Side assembly. Eight of these parts are now ready. Two for X-axis, four for Y-axis and two for Z-axis.
Printer settings for PLA plastic: 
Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

*Short Iddler Side printed successfully. Elapsed time: 09:43:00. Created .gcode file and started printing another set of parts: [http://opensourceecology.org/wiki/File:Universal_axis_motor_side.stl Motor Side] Estimated printing time for one set of four parts is 10:20:00. Eight of these parts are needed (two sets with current .stl file layout). 
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm 
Bottom/Top thickness: 1.2mm 
Fill density: 30% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 60 C 
Nozzle size: 0.4mm 
These settings are, at this time, random approximations based on basic configuration across different machine models for PLA.

=='''Thu Dec 14, 2017'''==

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

===Printing===

*Worked on [[D3D Australia]] log. 
2 Hours

==Fri Feb 02, 2018==

*3d printer assembly. Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for D3D 3D printer.

I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established. 
6 Hours

==Tue Jan 30, 2018==

*Test printing. Changed the steps per millimeter configuration on the z-axis.
*Printed a quick fix to add mechanical strength to the HBP support and keep the sandwich closed tight around the rods.

==Wed Jan 24, 2018==

*First day of test-printing and the machine performs very well considering where we come from. A few details need attention to improve the quality of the prints.
*Solved yesterday's issue with three-point probing. For some reason, the GCode in Cura had changed.
*Worked on D3D Australia log.

==Tue Jan 23, 2018==

*Worked on Marlin firmware values for probing points, travel limits after homing and extruder offset. I struggled to find a physical reference to match with what the values in the firmware where indication. The imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left. See details on [[D3D Australia]]

==Mon Jan 22, 2018==

*Worked on Marlin firmware. Half-succeeded at getting the Z-probe to stay within the boundaries of the HBP.
*Set the machine to print a cube in mid-air, without filament. It worked twice, then I had issues that I believe are related to the firmware. I must have accidentally changed something.
*Worked on D3D Australia log and the Troubleshooting section of the Product Manual where I added a table.

*Troubleshooting yesterday's problems. All day.
**Issues getting the motors to move. After exchanging some emails with Roberto and Marcin, and a fair bit of googling, some of these problems where solved. A couple of things remain unresolved. Heating of HBP is one of them. Relay module is on standby but there seems to be an issue with the activation signal from RAMPS.

*Finished design and printed alternative to cable chain.
*Finished routing wires.
*Watched Devs meeting video from Tuesday, Jan 9.
*Worked on uploading Marlin firmware to Arduino and tried to set up the printer. Issues arose:
**X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
**There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 0.2mm, it actually moves like 5 whole millimeters instead.
**The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time.

Followed guidelines from [http://opensourceecology.org/wiki/D3D_1612_Product_Testing Product Testing] in this wiki.

Belt tensioning mechanism works great. 

''Issues to resolve''
*With the current configuration, the X axis has a total travel of 191mm (7 1/2 in). Moving the end stop further towards Y2 on the X axis could increase this travel by 12mm (1/2 in).
*At the moment, the Z-axis sits 20mm offset towards Y2 in relation to the center of travel of the carriage on the X-axis' (center of bed on X).

*Affixed stepper motors to axes assemblies.
*Bought the twelve M6x30mm screws that needed to affix the axes to the frame and attached the Z-axis.
*Looked for references on the orientation of the motor terminals. I will go with the Y-axes diagonally down and back, X-axis and Z-axis diagonally up and left (towards Y1).
*Cut belts lengths.
I think that the instructions for the assembly of the axes can be made simpler in writing. Also, I need to work on a checklist for each step of the assembly.

*Looked for details on setting up the relay module for the HBP.
*Worked on D3D Australia Log.
===Some doubts===
Tried to figure out some details about the wiring of the relay to feed power to the HBP.
After a few hours of watching videos and reading some specifications about relays and MOSFETs, this is part of what I believe is correct:
#What I have is a 2 channel relay module, which is not the same than a MOSFET.
#I will split the positive wire going to the HBP and connect it to one of the relays. Let's say relay 1. I will connect one of the split ends of the wire to the NO1 position and the other one to the COM1. This means that while the coil of the relay is not energized, there will be no power going to the HBP.
#I will connect a pair of wires carrying 12V, coming directly from the PSU, to the DC+ and DC- terminals of the relay module.

'''Questions are:'''
*Where am I getting the signal to activate the relay from? I believe that I have to connect whatever single wire coming in from somewhere to the IN1 terminal of the module. Is that one wire coming from one of the terminals on the D8 position of the controller? Is it the + or - wire? And,
*Do I need to reset the jumpers on S1 and S2. At the moment the configuration is High-Com for both.
*On the extruder motor, the PHR-6 connector: Is the color sequence of the wires the same than for the rest of the stepper motors?

Tried different positions for each cut frame to see if I could get a reasonable square cube but I am not happy with the gaps along edges. I have returned the cuts to the engineering shop and re-ordered the frames from another place that uses a laser CNC table. Hope to have the parts by next week. I am now a week behind schedule on the 12-week plan. 
3 Hours

==Sun Dec 10, 2017==

Created hole templates to drill 3D printer frames. Made squaring aids with 30mmx30mm square box profile and worked on assembling the 3D printer's frame, but fail to glue the parts together. The cuts made by the plasma CNC machine at the engineering shop had to much angular error and the frames were not square.

==Sat Nov 04, 2017==

Looking for local vendors, Australian BOM for D3D Printer. Ordering parts. Due diligence: understanding specifications of parts to order the correct ones from alternative sources. Compromise between prices, shipping costs and shipping times. The paradox of choice. 
5 Hours

==Sun Oct 29, 2017==

As I read through the piled up information related to the D3D printer, I keep drifting away from the main objective of this twelve-weeks plan, this mainly due to the lack of knowledge on the subject. The learning process consumes most of my time at the moment. 
Embedded a copy of the August 12, 2017: RAMPS version of BOM to this log. I haven't yet made changes to it.

==Fri Oct 27, 2017==

Working on finding local vendors in Australia for the parts in the BOM. I think that many of the parts will be sourced from current vendor links since most of these parts are substantially more expensive here. 
4 Hours

==Tue Oct 24, 2017==

Kept at chasing links related to D3D printing development. List of parts, assembly, BOM, etc. Worked on a slide to outline a 12-week plan to put together a prototype here in Australia and evaluate the chances of at least gathering the parts in Argentina to build another machine over there. 
See slides under title: 3D Printer: all links. 
3 Hours

==Sun Oct 22, 2017==

Made an attempt to track all links related to D3D printing spread around OSE Wiki. I found this to be a time-consuming task, in part because I did not participate in the R&D process. Nevertheless, I believe that this information should be better organized to facilitate accessibility to all newcomers and those wanting to learn the basis of each development. This could also be related to my lack of overall familiarity with the way logs are kept. This exercise was still useful to learn several details associated to the D3D printing project. 
2 Hours

==Thu Oct 19, 2017==

Watched some more free CAD tutorials and revisited Roberto's video several times. Phone talk with Marcin. Started putting together a twelve-week plan to build the 16" 3D printer here in Australia.

==Wed Oct 18, 2017==

Went through some more of the meetings and added minutes in a comment for the meeting of Wed Sep 27, 2017. Just by accident learned that YouTube automatically creates links for the time format 00:00:00 so one can create a sort of time index where different topics can be easily found within the video. This was a personal exercise in an attempt to keep track of the topics being discussed, but I think we should look at making it a standard addition to the videos. e.g.

==Fri Sep 08, 2017==

*Watched Aug 29 meeting video once again. Watched Sep 05 meeting video. I'm starting to find my bearings. 
Important information from meetings is easy to overlook when one is not familiar with the details of what is going on and have to deal with many new concepts and tools. 
Going to the supermarket to buy a notepad (handy for when I watch the videos on devices other than my laptop). 
Left the Sep 05 meeting video halfway through thinking that I knew where to go and that it was going to be easy to find, but encountered the same issue as I did many times before: got lost in the Wiki. It reminds me, somehow, to those neighborhoods where the streets are not straight and one ends many times in some cul de sac.
*Added a link to the Tractor Construction Set 2017 and to the Power Cube v17.08 to this log. 
*Started working on the Master CAD file for the Micro Tractor this evening. I managed to put the four holes to support the motors on the brackets but I think the large bore has to be reduced in order to have more material between the edge of the bore and the orifices for the bolts.
*Uploaded a new file for the motor brackets with the four holes to attach the motor. Not sure whether that is ok but I put it there just in case.
*I struggle with the constraint of parts in the assembly 2 workbench. I still don't know how to get one part or the other to stay in its place.
*I cannot preview my edits in the Wiki. I always have to save in order to view changes.

Encountered some troubles trying to fit the nut to the bolt. Not familiar with what ISOs are a match between the fasteners. Also, the Screw Hole Calculator says that a M30 screw should fit a hole of 26.5 mm but if I measure the M30 bolt with the ruler it says 29.91 mm approx. I do not know how to understand this discrepancy at the moment.

==Sat Aug 12, 2017==

Another long afternoon in front of the computer with FreeCAD. It has been very frustrating at times. It reminds me of the days in which I wanted to format a letter in MSWord and had no clue on how to do it. Things are intuitive, but not so.
*Learned some characteristics of the Sketcher workbench and how to toggle between workbenches to access the tools needed for differents parts of the job.
*Encountered a problem that I have not been able to solve yet. When I try to sink or stretch my sketch on the face of one of the tubes a dialog box appears saying that ''the shape is not perfect or that it's not closed'' (need to investigate). The program also freezes for a couple of minutes.

*Worked on [[D3D Australia]] log. 
2 Hours

==Fri Feb 02, 2018==

*3d printer assembly. Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for D3D 3D printer.

I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established. 
6 Hours

==Tue Jan 30, 2018==

*Test printing. Changed the steps per millimeter configuration on the z-axis.
*Printed a quick fix to add mechanical strength to the HBP support and keep the sandwich closed tight around the rods.
See [[D3D Australia]] 
4 Hours

==Wed Jan 24, 2018==

*First day of test-printing and the machine performs very well considering where we come from. A few details need attention to improve the quality of the prints.
*Solved yesterday's issue with three-point probing. For some reason, the GCode in Cura had changed.
*Worked on D3D Australia log.
See [[D3D Australia]] 
6 Hours

==Tue Jan 23, 2018==

*Worked on Marlin firmware values for probing points, travel limits after homing and extruder offset. I struggled to find a physical reference to match with what the values in the firmware where indication. The imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left. See details on [[D3D Australia]] 
6 Hours

==Mon Jan 22, 2018==

*Worked on Marlin firmware. Half-succeeded at getting the Z-probe to stay within the boundaries of the HBP.
*Set the machine to print a cube in mid-air, without filament. It worked twice, then I had issues that I believe are related to the firmware. I must have accidentally changed something.
*Worked on D3D Australia log and the Troubleshooting section of the Product Manual where I added a table.

*Troubleshooting yesterday's problems. All day.
**Issues getting the motors to move. After exchanging some emails with Roberto and Marcin, and a fair bit of googling, some of these problems where solved. A couple of things remain unresolved. Heating of HBP is one of them. Relay module is on standby but there seems to be an issue with the activation signal from RAMPS.
*Worked on D3D Australia.

*Finished design and printed alternative to cable chain.
*Finished routing wires.
*Watched Devs meeting video from Tuesday, Jan 9.
*Worked on uploading Marlin firmware to Arduino and tried to set up the printer. Issues arose:
**X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
**There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 0.2mm, it actually moves like 5 whole millimeters instead.
**The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time.

Followed guidelines from [http://opensourceecology.org/wiki/D3D_1612_Product_Testing Product Testing] in this wiki.

*Glued heated bed to the holder and attached it to the carriage on the Z-axis.
*Routed HBP power wires to relay module and PSU.
*Wired and installed relay module.
*Designed and printed insulating box for relay module.
*Edited D3D Australia log.

==Wed Jan 03, 2018==
*Trimmed 2mm from M6x30 SS screws.
*Generated .stl and .gcode files and printed belt pegs.
*Finished the assembly and attached X and Y axes to frame.
Belt tensioning mechanism works great. 

''Issues to resolve''
*With the current configuration, the X axis has a total travel of 191mm (7 1/2 in). Moving the end stop further towards Y2 on the X axis could increase this travel by 12mm (1/2 in).
*At the moment, the Z-axis sits 20mm offset towards Y2 in relation to the center of travel of the carriage on the X-axis' (center of bed on X). 
3 Hours

==Tue Jan 02, 218==
*Affixed stepper motors to axes assemblies.
*Bought the twelve M6x30mm screws that needed to affix the axes to the frame and attached the Z-axis.
*Looked for references on the orientation of the motor terminals. I will go with the Y-axes diagonally down and back, X-axis and Z-axis diagonally up and left (towards Y1).
*Cut belts lengths.
I think that the instructions for the assembly of the axes can be made simpler in writing. Also, I need to work on a checklist for each step of the assembly. 
3 Hours

==Mon Jan 01, 2018==
*Worked on the wiring of the controller. Changed the sequence of the wires on a PHR-4 terminal and soldered the wires of the Dupont connector from the extra end stop to the inductive sensor's wires. Connected the cables for all the axes, end stops, Z probe and extruder motor to the controller,
*Looked for details on setting up the relay module for the HBP.
*Worked on D3D Australia Log.
===Some doubts===
Tried to figure out some details about the wiring of the relay to feed power to the HBP.
After a few hours of watching videos and reading some specifications about relays and MOSFETs, this is part of what I believe is correct:
#What I have is a 2 channel relay module, which is not the same than a MOSFET.
#I will split the positive wire going to the HBP and connect it to one of the relays. Let's say relay 1. I will connect one of the split ends of the wire to the NO1 position and the other one to the COM1. This means that while the coil of the relay is not energized, there will be no power going to the HBP.
#I will connect a pair of wires carrying 12V, coming directly from the PSU, to the DC+ and DC- terminals of the relay module.

'''Questions are:'''
*Where am I getting the signal to activate the relay from? I believe that I have to connect whatever single wire coming in from somewhere to the IN1 terminal of the module. Is that one wire coming from one of the terminals on the D8 position of the controller? Is it the + or - wire? And,
*Do I need to reset the jumpers on S1 and S2. At the moment the configuration is High-Com for both.
*On the extruder motor, the PHR-6 connector: Is the color sequence of the wires the same than for the rest of the stepper motors?

*Drilled and redrilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*The bearings for the idlers that I received do not have flanges. I will 3D print a set of washers that will reduce the friction of the belt against the sides of the bearings' receptacle on the short idler side.
*Worked on D3D Australia log.

==Tue Dec 19, 2017==

The 3D printed parts with the brim are pretty much perfect. Removed brim and assembled two carriages. They slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. Used a ZAP brand clear epoxy. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. Only tack weld it at this point.

Short Iddler Side printed successfully. Created .gcode file and started printing another set of parts (Motor Side). Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). Put together some of axes parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing. br>

3 Hours

==Sun Oct 22, 2017==

Made an attempt to track all links related to D3D printing spread around OSE Wiki. I found this to be a time-consuming task, in part because I did not participate in the R&D process. Nevertheless, I believe that this information should be better organized to facilitate accessibility to all newcomers and those wanting to learn the basis of each development. This could also be related to my lack of overall familiarity with the way logs are kept. This exercise was still useful to learn several details associated to the D3D printing project.

Went through some more of the meetings and added minutes in a comment for the meeting of Wed Sep 27, 2017. Just by accident learned that YouTube automatically creates links for the time format 00:00:00 so one can create a sort of time index where different topics can be easily found within the video. This was a personal exercise in an attempt to keep track of the topics being discussed, but I think we should look at making it a standard addition to the videos. e.g.

*Watched Aug 29 meeting video once again. Watched Sep 05 meeting video. I'm starting to find my bearings. 
Important information from meetings is easy to overlook when one is not familiar with the details of what is going on and have to deal with many new concepts and tools. 
Going to the supermarket to buy a notepad (handy for when I watch the videos on devices other than my laptop). 
Left the Sep 05 meeting video halfway through thinking that I knew where to go and that it was going to be easy to find, but encountered the same issue as I did many times before: got lost in the Wiki. It reminds me, somehow, to those neighborhoods where the streets are not straight and one ends many times in some cul de sac.
*Added a link to the Tractor Construction Set 2017 and to the Power Cube v17.08 to this log. 
*Started working on the Master CAD file for the Micro Tractor this evening. I managed to put the four holes to support the motors on the brackets but I think the large bore has to be reduced in order to have more material between the edge of the bore and the orifices for the bolts.
*Uploaded a new file for the motor brackets with the four holes to attach the motor. Not sure whether that is ok but I put it there just in case.
*I struggle with the constraint of parts in the assembly 2 workbench. I still don't know how to get one part or the other to stay in its place.

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. <del>But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.</del>

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above. This discrepancy is associated with the difference in the geometry of this machine compared with OSE's standard. The motor on the X-axis should be on the Y1 side.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

===Wiring===

*Routed more wires in the machine.
*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

===Assembly===

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Assembly===

*Drilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

=='''Sat Dec 23, 2017'''==

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm

These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

=='''Thu Dec 14, 2017'''==

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. <del>But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.</del>

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above. This discrepancy is associated with the difference in the geometry of this machine compared with OSE's standard. The motor on the X-axis should be on the Y1 side.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

===Assembly===

*Glued the last 16in square to the frame and trimmed excess epoxy (+-1 hour). 

===Printing===

*Printed a second set of Motor Side assembly. Eight of these parts are now ready. Two for X-axis, four for Y-axis and two for Z-axis.

Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

*Short Iddler Side printed successfully. Elapsed time: 09:43:00. Created .gcode file and started printing another set of parts: [http://opensourceecology.org/wiki/File:Universal_axis_motor_side.stl Motor Side] Estimated printing time for one set of four parts is 10:20:00. Eight of these parts are needed (two sets with current .stl file layout).

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

=='''Fri Feb 02, 2018'''==

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. <del>But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.</del>

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above. This discrepancy is associated with the difference in the geometry of this machine compared with OSE's standard. The motor on the X-axis should be on the Y1 side.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

*Drilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

=='''Tue Dec 19, 2017'''==

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm

These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

Printer settings for PLA plastic: 
Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

=='''Fri Feb 02, 2018'''==

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. <del>But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.</del>

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above. This discrepancy is associated with the difference in the geometry of this machine compared with OSE's standard. The motor on the X-axis should be on the Y1 side.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

=='''Mon Jan 08, 2018'''==

===Assembly===

*Cut heat-resistant rubber to use as a spacer between heated bed and bed rods.
*Rearranged end stops to shorten the length of travel on Y and lengthen it on X.
*Installed step motor controllers on RAMPS board.
*Adjusted X-axis so it is parallel to frame.

===Notes===

''To be edited:''
*Check squareness on X-Y and X-Z when installing X
*Rubber used is recycled from scrap. Maybe tyre rubber could do the job. The only limitation is temperature.
*End stops modified searching for ideal travel range on X and Y.

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

===Assembly===

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

===Assembly===

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Assembly===

*Drilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

=='''Tue Dec 26, 2017'''==

*The spacers described under "Printing" are not necessary unless you do not feel like walking to the hardware store for some washers.
*Do not use the holes-template tool described under "Printing".

*Template to accurately place holes on metal frame.
*Set of 12 spacers to separate the bolted axes assemblies from the metal frame. Inbuild separation is 2mm.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

=='''Sat Dec 23, 2017'''==

===Assembly===

*Assembled carriages for the four axes (+- 15 min per assembly) and glued the magnets on the x-axis carriage. See notes for more details about this assembly.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm

Fill density: 25% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 50 C

These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

Printer settings for PLA plastic: 
Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

*Short Iddler Side printed successfully. Elapsed time: 09:43:00. Created .gcode file and started printing another set of parts: [http://opensourceecology.org/wiki/File:Universal_axis_motor_side.stl Motor Side] Estimated printing time for one set of four parts is 10:20:00.

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. <del>But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer.

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

===Wiring===

*Routed more wires in the machine.
*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along.

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

===Wiring===

*Routed more wires in the machine.
*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm 
Bottom/Top thickness: 1.2mm 
Fill density: 25% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 50 C 
Nozzle size: 0.4mm 
These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

===Printing===

Generated .gcode file for [http://opensourceecology.org/wiki/File:Universal_axis_carriage_side.stl Carriage Side] and started the printing process. Estimated printing time for one set of four parts is 11:00:00. Eight of these parts are needed (two sets with current .stl file layout).

===Assembly===

*Glued the last 16in square to the frame and trimmed excess epoxy (+-1 hour). 

===Printing===

*Printed a second set of Motor Side assembly. Eight of these parts are now ready. Two for X-axis, four for Y-axis and two for Z-axis.
Printer settings for PLA plastic: 
Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

*Short Iddler Side printed successfully. Elapsed time: 09:43:00. Created .gcode file and started printing another set of parts: [http://opensourceecology.org/wiki/File:Universal_axis_motor_side.stl Motor Side] Estimated printing time for one set of four parts is 10:20:00.

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Printing===

*First day of test-printing and the machine performs very well considering where we come from. I have printed four cubes and three cones as guides to have an idea of the possible modifications needed. A few details need attention.
*Solved yesterday's issue with three point probing. For some reason the GCode in Cura had change. In the following table you can see the lines added to get the probing going once again:

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

===Wiring===

*Routed more wires in the machine.
*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

===Assembly===

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Assembly===

*Drilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

=='''Tue Dec 26, 2017'''==

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

=='''Sat Dec 23, 2017'''==

*Assembled carriages for the four axes (+- 15 min per assembly) and glued the magnets on the x-axis carriage. See notes for more details about this assembly.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

=='''Tue Dec 19, 2017'''==

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm

Fill density: 25% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 50 C

These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

Printer settings for PLA plastic: 
Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

*Short Iddler Side printed successfully. Elapsed time: 09:43:00. Created .gcode file and started printing another set of parts: [http://opensourceecology.org/wiki/File:Universal_axis_motor_side.stl Motor Side] Estimated printing time for one set of four parts is 10:20:00.

=='''Thu Dec 14, 2017'''==

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

=='''Fri Feb 02, 2018'''==

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

===Assembly===

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Assembly===

*Drilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

=='''Tue Dec 26, 2017'''==

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

=='''Sat Dec 23, 2017'''==

*Assembled carriages for the four axes (+- 15 min per assembly) and glued the magnets on the x-axis carriage. See notes for more details about this assembly.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm

Fill density: 25% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 50 C

These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

Printer settings for PLA plastic: 
Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

===Assembly===

*Rearranged X-axis, PSU, HBP and control board to suit OSE's standard geometry for this machine. This involved the drilling of two extra holes on the frame to displace the Z-axis towards Y2 and the removal and regluing of the HBP from its supporting rods. The end stops on both, X and Y-axis needed modifications also. See images.

===Notes===

Having the abovementioned circumstances in consideration and thinking back on the original assembly described in this log, I would recommend placing the installation of the Z-axis and HBP as the absolute last step in the assembly process. This at least until an accurate, standardized, position for the holes on the frame can be established.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)

#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

===Wiring===

*Routed more wires in the machine.
*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per millimeter configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm, although 82 steps/mm could be a better approximation.
*Printed a rectangular frame to fit around the short idler side sandwich that holds the HBP. This frame is a quick fix to add mechanical strenght to the HBP support and keep the sandwich closed tight around the rods.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization (at least for now) that the issues that I was having on the Z-axis (squashed layers) were related to the increments on the movement of the axis being shorter than expected and the nozzle was rubbing on the previously extruded layer of the print and that the fused material of each newly deposited layer was being squeezed to the sides of the nozzle path. See image with test cones' top view (shape of a witch hat).

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

===Wiring===

*Routed more wires in the machine.
*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

===Printing===

*Test printing. Finally managed to get the resolution on the base of the cone (see pictures). I had to change the steps per minutes configuration on the z-axis to achieve this result. I did it by adding an M92 code line in Cura's Start GCode. I changed it from 80 steps/mm to 83 steps/mm. 82 could be a better approximation.

===Notes===

*After printing several test cubes and cones, I did something that I had neglected doing up to that point: measured the dimensions of the prints with the vernier caliper. I came then to the realization that the issues that I was having on the Z

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first ten or so layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

===Wiring===

*Routed more wires in the machine.
*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

=='''Tue Dec 19, 2017'''==

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm

Fill density: 25% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 50 C

These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

===Printing===

Generated .gcode file for [http://opensourceecology.org/wiki/File:Universal_axis_carriage_side.stl Carriage Side] and started the printing process. Estimated printing time for one set of four parts is 11:00:00. Eight of these parts are needed (two sets with current .stl file layout).

===Assembly===

*Glued the last 16in square to the frame and trimmed excess epoxy (+-1 hour). 

===Printing===

*Printed a second set of Motor Side assembly. Eight of these parts are now ready. Two for X-axis, four for Y-axis and two for Z-axis.
Printer settings for PLA plastic: 
Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

*Short Iddler Side printed successfully. Elapsed time: 09:43:00. Created .gcode file and started printing another set of parts: [http://opensourceecology.org/wiki/File:Universal_axis_motor_side.stl Motor Side] Estimated printing time for one set of four parts is 10:20:00.

=='''Thu Dec 14, 2017'''==

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first few layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firmware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

===Wiring===

*Routed more wires in the machine.
*Started designing an alternative to cable chain to route the wiring for the X-axis. The length of the stepper motor cables that I currently have is not enough to use with the cable chain. This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]
*'''Important''': You have 15 jumpers that come whit your RAMPS. They Must be installed under the Pololu drivers, three jumpers under each driver.

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

===Assembly===

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Assembly===

*Drilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

=='''Tue Dec 19, 2017'''==

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm 
Bottom/Top thickness: 1.2mm 
Fill density: 25% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 50 C

These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

=='''Sun Dec 17, 2017'''==

*Glued the last 16in square to the frame and trimmed excess epoxy (+-1 hour). 

===Printing===

*Printed a second set of Motor Side assembly. Eight of these parts are now ready. Two for X-axis, four for Y-axis and two for Z-axis.
Printer settings for PLA plastic: 
Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

=='''Thu Dec 14, 2017'''==

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.

===Issues to resolve===

*There is too much oscillation in the heated bed on the X-axis. This is caused by the momentum generated by the movement of the carriages along the axes. I will work on the HBP attachment to the Z carriage to try to reduce it.
*The first few layers are being squashed by the extruder nozzle.

===Notes===

I have modified the voltage on the Pololu drivers. Raised it from 0.6V to 0.8V.

=='''Tue Jan 23, 2018'''==

===Software===

*Worked on Marlin firmware's values for probing points, travel limits after homing and extruder offset. The order that I consider correct to work on these three points is as follows:

'''Within Arduino IDE --> configuration.h -->'''

'''1-''' ''Travel limits after homing:'' Do this one first to make sure that the X and y axes' carriages stop before overshooting their maximum physical travel limits on the side opposite the end stops. This also defines the limits of your HBP area. The limits set in Cura while setting up the D3D machine profile did not work for me.

// @section machine

// Travel limits after homing (units are in mm)
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Y_MAX_POS 190 //Changed this value from 250 GC
#define X_MAX_POS 200 //Changed this value from 250 GC
#define Z_MAX_POS 200 //Changed this value from 250 GC

'''2-''' ''Auto Bed Leveling (ABL) probing points:'' Once your maximum travel limits (bed area) are set, you guarantee that you cannot accidentally set these probing points outside the bed area in the firmware. If you set up a point that falls outside the bed area, a warning message will be displayed in the Arduino Sketcher when you verify the code. These points are simple cartesian coordinates but it could get tricky if you don't have a clue of where the imaginary origin of the coordinates is on the surface of your bed. In the case of this machine, with the default settings, the origin of coordinates (0,0) is on the front right corner of the machine, opposite the HOME position on Y.

#elif ENABLED(AUTO_BED_LEVELING_3POINT)

// 3 arbitrary points to probe.
// A simple cross-product is used to estimate the plane of the bed.
#define ABL_PROBE_PT_1_X 40 // Changed this value from 40 GC
#define ABL_PROBE_PT_1_Y 20 // Changed this value from 200 GC
#define ABL_PROBE_PT_2_X 105 // Changed this value from 40 GC
#define ABL_PROBE_PT_2_Y 190 // Changed this value from 40 GC
#define ABL_PROBE_PT_3_X 170 // Changed this value from 200 GC
#define ABL_PROBE_PT_3_Y 20 // Changed this value from 40 GC

'''3-''' ''Extruder offset:'' This is the final step to ensure that you can utilize the whole of the printing area right to its boundaries. In this machine the inductive sensor is offset 14mm to the back (towards Z) and 38mm to the left (towards Y1) of the extruder nozzle. With this in consideration, and following the guidelines set by the box drawn on the left, the values to input in the lines under the boxes below should be: X OFFSET -38 and Y OFFSET 14. But note that the boxes below are mirror images and it is the box to the right the one that represents the actual configuration in this printer. As such, the sign for the X offset value remains positive.

// +-- BACK ---+ +-- BACK ---+
// | | | |
// L | (+) P | R <-- probe L | (+) P | R <-- probe
// E | | I E | | I
// F | (-) N (+) | G <-- nozzle F | (+) N (-) | G <-- nozzle
// T | | H T | | H
// | (-) | T | (-) | T
// | | | |
// O-- FRONT --+ +-- FRONT --0
// (0,0)
#define X_PROBE_OFFSET_FROM_EXTRUDER 38 // X offset: -left +right [of the nozzle] Changed from 20 GC
#define Y_PROBE_OFFSET_FROM_EXTRUDER 14 // Y offset: -front +behind [the nozzle] Changed from 10 GC
#define Z_PROBE_OFFSET_FROM_EXTRUDER -0.05

===Notes===

I struggled to find a physical reference to match with what the values in the firmware where indicating. Part of the problem was that the imaginary +X of the cartesian coordinates on the HBP is inverted, that is, it increases in value to the left, as explained above.

'''Attention''': If you decide to modify the firmware and check each one of these steps on the machine before continuing with the following one, keep well in mind that the inductive sensor is offset from the nozzle and you will have to be ready to pull the plug from the wall if you see it falling outside the bed while proving.

===Issues to resolve===

The machine is not probing the three points anymore. I suspect that there could be a hiccup in the Marlin firmware or in the GCode in Cura. This happened suddenly, for no obvious reasons.

=='''Fri Jan 19, 2018'''==

===Troubleshooting===

Worked on yesterday's problems.

*All issues with the axes were resolved after installing the jumpers underneath the Pololu drivers.
*To solve the issue with the HBP, the relay module was left connected to D8- and both trigger jumpers were swapped to trigger on Low. I was getting an error message in Cura that read like this:

< Error:MINTEMP triggered, system stopped! Heater_ID:bed 
< Error:Printer halted. Kill() called!

This message was due to a faulty thermistor installed in the heated bed.

===Notes===

Two temperature values should be displayed automatically on the title bar of Cura's control panel when the printer is connected: one for the bed and the other for the extruder. When the power is off, both values are going to be very similar to each other and close to room temperature. If one or no value is displayed, then there is a problem with the signal from the thermistor and you need to find the fault.

===Issues to resolve===

*Firware. Printing area and Z-probe offset from extruder nozzle.

===Wiring===

*Finished routing wires.

===Software===

*Worked on uploading Marlin firmware to the Arduino board and tried to set up the printer.

===Printing===

Finished design and printed alternative to cable chain.

===Issues to resolve===

*X and Y axes move freely by hand but are not working when powered using the control panel in Cura. The motors receive power but instead of moving one way or another they are locked in place.
*There is a lot of vibration on the belt of the Z-axis on the side where the peg holds the belt to the carriage. One can also hear a noise. This happens while manually operating the axis using the printer control panel in Cura. The interesting thing is that if I use the bed leveling function from the top menu, the noise and vibration disappear. Also, the actual range of movement of the bed is much larger than the indicated values on the screen: if I send a signal to move it by 10mm, it actually moves 160mm millimeters.
*The relay module is being constantly powered by the RAMPS and the heated bed heats up to max temp all the time. I tried swapping the cable to the minus (-) connector on D8 but both terminals (+ and -) seem to be powered all the time (not quite).

This design will use a commercially available plastic spiral wrap to keep the wires out of the way of the moving parts.

===Notes===

*During this stage, it is very important to make sure, to double check, that you are connecting the wires as specified on slides 2, 3 and 4 in this link: [http://opensourceecology.org/wiki/D3D_Controller#Wiring Wiring]

===Assembly===

*Grouped the controller-end of the extruder and heated bed termistors in a single PHR-4 connector. It is a bit harder to remove the wires from this type of connector than from the Dupont ones, but still doable.
*Installed sensor holder on extruder. I recommend you to trim the vanes of the heatsink only to the point where you can fit the sensor holder underneath the cooling fan. By doing so, you are ensuring that there is still a good amount metal in that area to take away the heat from the assembly and to provide separation between the sensor holder and the base of the heatsink. Language agnostic instructionals for this assembly, [http://opensourceecology.org/wiki/3D_Printer_Construction_Set_Workshop_August_12,_2017#Extruder here].
*Marked on the frame the range of movement available on the X and Y axes to have an idea of the printable area size and position.

===Notes===

The current position of the stepper motor on X is towards Y2 and front side. With this configuration, I get a maximum range of travel on X of 7 1/2in (191mm) and of 7 3/8 in (188mm) on Y. The aim is to increase the range to 8in on both axes. Also, the Z-axis will need to be offset towards Y1 to compensate for asymmetry on X-axis configuration.

===Assembly===

*Trimmed 2mm from M6x30 SS screws. These screws were slightly longer than needed and were jacking the nuts against the outer wall of the catchers on the idler and motor side of X and the bed dupport on Z.
*Finished the assembly of the X and Y axes and attached them to frame. A reference for tightening the belt: set the carriage halfway along the its axis and press both sides of the belt with your index finger and your thumb until you feel a noticeable amount of resistance. If the gap is of around about 8 to 10 mm, then it's tight enough

===Printing===

*Printed belt pegs for carriages. I changed the orientation of the pegs on the .stl file and printed them with the shortest leg at the base to avoid bridging along the belt slot.

===Assembly===

*Soldered wires to HBP. Minimum soldering iron power should be 40 Watt, and you need patience. Tested the heated bed by connecting it directly to the power supply. The maximum temperature reached was 105 deg centigrades.
*Deburred some of the 3D printed parts (bridged filaments from nut/screw sockets) and assembled axes y and x.
*Installed pulleys on stepper motors. An easy way to go about this task is to use something like one of the idler bearings as a reference for the placing of the pulleys. I placed the bearing on top of the pulley and lined up the top face of the bearing with the bottom of the chamfer on the motor axle.

''Gluing magnets to x-axis carriage and extruder motor interface''. You will need some tape (stationary type), cyanoacrylate or epoxy glue, a flat steel surface (top of your fridge, for example), something heavy (books), printed carriage and extruder interface parts and magnets. 
Best advisable way to do this is as follows:
#Make sure that the surface in the bottom of the magnet sockets of both parts is going to provide a solid base for the glue. In my parts, I had a first layer of extruded PLA that was not strongly bonded to the next layer so I scraped the bits that were loose with a blade. See pictures.
#Glue the magnets on the carriage side first. It's better if you have the carriage already assembled so any irregularity in the plane shared by the magnets can be corrected by the gluing process. If you are using epoxy, as I did, to glue these magnets in one attempt you will need to use some stationary or packing tape. I recommend you also to practice placing the magnet without glue first to have an idea of their behavior. It will be frustrating at first. Place a drop of epoxy in all the slots, make sure that it will be enough to climb up the sides and fill the gap between the magnet and the wall of the slot. Start placing the magnets in the slots from either the top or bottom side of the carriage and complete one row at a time. There are 5 rows. Skip rows 2 and 4 (single magnet rows) on your first pass to make the job easier. As you finish placing the magnets in one row, use a bit of tape to hold them down and then move to the next row. Make sure that there are no wrinkles on the surface of the tape. Remember that the magnets have to be placed in the same orientation.
#Once all the magnet are placed and hold down by the tape, find your flat metal surface and stick the carriage to it adding a few books on top for pressure. It is better if you find a flat bit of steel that you can sit on top of the carriage to stop the glue from running out of the receptacles.
#Once the glue has cured, remove the tape and scrape any excess glue from the surface of the magnets. Proceed then to stick the motor interface's magnets to the magnets already glued on the carriage side. Place a drop of epoxy in all the slots of the extruder interface and lay it down on top of the carriage. Line up/square the edges of both parts, flip the assembly around and sit it on top of one of the motor assemblies (with the motor on it) to dry. Don't forget to put some books on top. By doing this you are ensuring both, a perfect axial alignment of the poles of all magnets and of all the magnets' surfaces on the plane.

===Assembly===

*Drilled holes in the metal frame.
*Put together one of the axes assemblies and test fitted it to the z-axis and y-axes holes to check for alignment, spacing and freedom of movement of the carriage.
*To mount the axes in this fashion is necessary to replace 12 of the M6x18mm Cap Screws by 12 M6x30mm Hex head screws in the BOM. 12 Washers can also be included.

===Notes===

*After using the 3D printed template to place the marking of the holes, and after drilling the holes, I realized that the carriage sandwich has an overall height that is 8mm larger than the end idler and motor assemblies. This offsets the top and bottom of the carriage by 4mm in relation to the two ends of the axis assembly. I repositioned all the holes down by 6mm and redrilled to accommodate for this hiccup (4mm would have sufficed but I went with 6 to be able to drill next to the other holes)
*After printing the spacers to fit the axis assemblies to the frame, I came to the realization that I had forgotten the existence of the nut catchers in the idler and motor side sandwiches. I am not sure at this stage if I should have aimed to mount the axes using these catchers. Since I had already made my mind about mounting the axes using two of the holes that press the sandwiches together, I decided to continue on that path.

*The spacers described under "Printing" are not necessary unless you do not feel like walking to the hardware store for some washers.
*Do not use the holes-template tool described under "Printing".

*Template to accurately place holes on metal frame.
*Set of 12 spacers to separate the bolted axes assemblies from the metal frame. Inbuild separation is 2mm.

===Notes===
*The creation of these files served as a FreeCAD training exercise to me, and although the result is as I intended, the organization of the different elements inside the FreeCAD files leaves much to be desired.
*The template tool is, as from now, deprecated. The idea is good for a building workshop where many units are being assembled and if you have not gotten the holes cut on the frames. At this stage, nevertheless, the holes need to be repositioned to accommodate for the offset position of the carriage on the axis assemblies.

=='''Sat Dec 23, 2017'''==

*Assembled carriages for the four axes (+- 15 min per assembly) and glued the magnets on the x-axis carriage. See notes for more details about this assembly.

===Printing===

Finished the design an printed a corner template to place marks on the metal frame where the holes that hold the axes in place are meant to be located. This tool provides an accurate way to place the marks for the holes on both the motor side and short idler side of the carriage on any corner of the cube. The file for this template has not been uploaded to the wiki yet since it needs a modification.

===Notes===

While putting the carriages together, one can notice that the linear bearings do not have a snug fit in the sandwiched assembly. I noticed this by shacking the assembly. To fix it, I have wrapped each bearing with two layers (two turns of the bearing) of clear packing tape. This increases the diameter of the bearings to between 15.15mm and 15.20mm. By doing so, one can reduce the amount of oscillation of the carriage during the operation.

===Assembly===

Removed brim from the new set of Carriage Side and assembled them. The carriages slide with no resistance on the shafts. Started cleaning the frame for painting and the epoxy glue started cracking in parts and separating from the frame in others. I am not sure about the reasons but it could be a combination of factors. I disassembled the cube and started from scratch. This time I decided to weld it with a TIG machine. I only tack welded it at this point.

===Notes===

The idea of the metal frame is appealing because of its structural rigidity, and one also needs to consider that it was designed with the use of magnets for the axes in mind. Nevertheless, I found the assembly of the frame to be a rather cumbersome process without a precise way of squaring the corners. I would consider alternatives in a future build. Used a ZAP brand clear epoxy glue for the frame's first assembly, for the record.
The 3D printed parts with the brim are pretty much perfect.

=='''Mon Dec 18, 2017'''==

===Assembly===

Assembled two carriages and checked the alignment of linear bearings on one of the assembled axes' rods. Bearings are slightly misaligned due to warping of printed parts.

===Printing===

Carriage Side parts are fairly warped, in part due to printer settings.
Created a new .gcode file for the Carriage Side to try to reduce the warping on these parts.
Printer settings for PLA plastic: 
Layer height: 0.2mm 
Shell thickness: 1.2mm 
Bottom/Top thickness: 1.2mm 
Fill density: 25% 
Printing Speed: 50mm/s 
Printing temp: 200 C 
Bed temp: 50 C 
Nozzle size: 0.4mm 
These settings are, at this time, random aproximations based on basic configuration across different machine models for PLA.

===Notes===

Brought the printing settings back to default, reduced the HBP temperature to 50 deg C and added a brim in an effort to minimize warping.

*Glued the last 16in square to the frame and trimmed excess epoxy (+-1 hour). 

===Printing===

*Printed a second set of Motor Side assembly. Eight of these parts are now ready. Two for X-axis, four for Y-axis and two for Z-axis.
Printer settings for PLA plastic: 
Same as previous day.

=='''Fri Dec 15, 2017'''==

===Assembly===

*Preparing (straightening bows, sanding of edges, degreasing), squaring and gluing of 16" D3D frame (+-4 hours). As with the first set of squares that I got cut out, all of these squares presented some degree ob bowing due, I believe, to the heat generated by the cutting process on a plate that, at 3mm, is relatively thin. 
*Put together some of the axes' parts to check the squareness of the 8mm rods. Prints are very precise. Rods are parallel across all planes. Assembled HBP support. Possible issues could be sagging of the far end of the heated bed after some use and jittering of bed if Z-axis needs to work too hard for the auto leveling during the printing.

===Printing===

*Short Iddler Side printed successfully. Elapsed time: 09:43:00. Created .gcode file and started printing another set of parts: [http://opensourceecology.org/wiki/File:Universal_axis_motor_side.stl Motor Side] Estimated printing time for one set of four parts is 10:20:00.

=='''Thu Dec 14, 2017'''==

===Printing===

*First set of parts printed with a fault (shift on Y-axis position halfway through the printing process). Replaced end-stop micro switch. Checked motor driver. Swapped X-axis driver with Y-axis driver. The problem seems to be solved. Probably just a bad contact in the driver's connection. Created .gcode file for Extruder Holder. Extruder holder printed successfully. Created .gcode file for Short Idler Side. And started the printing process.
Printer settings for PLA plastic: 
Same as previous day.

===Notes===

Bridging. There are strings of filament that did not anchor to the edges of the magnet's socket-bases and nut's socket-bases. The filament fell into these socket's space during the printing process. Part of the problem is due to gaps in the printed perimeter of the sockets. These gaps are the result of the proximity or intersection between the perimeters of various sockets with each other and with the outer shell of the part.

===Suggestions===

Check .stl and .fcstd files to try to solve this issue.

=='''Wed Dec 13, 2017'''==

I have all the parts required except for the 3D printed parts. I am printing my own parts and I will be learning the basics of the printing process as I move along. For this reason, this log will contain some details concerning printer settings that I will be trying with the different parts necessary for OSE's design. These settings may or may not be of use later on but are, I believe, a good reference point.
