==Printer Extruder==<br />
<br />
{{Hint|Note the small extruder gear shown is MK8- we are using an MK7. '''Note''': Supervolcano nozzle has heat transfer issues, so we are using a 3 mm E3D v6 heat break with success (6mm threads on both sides - note that E3D v6 has 6 mm on the nozzle side, 7 mm on the cold side. Can also test Titan Aero v6 1.75 mm - which appears to have 6 mm thread on both sides. 3mm titan aero is definitely 6 mm thread on each side: see [[E3D_Titan_Aero_Extruder#CAD]]}}<br />
<br />
'''Notes''': Still missing from final assembly by MJ: fan, heat sink heat exchanger, MK7 gear, spring. In final CAD of extruder assy, heat break does not stick out of the heat sink. In reality, it sticks out about 3 mm. Where is the discrepancy if the heat break is 25 mm long?<br />

Speculation on reuse of n95 masks: Can you heat treat the masks at 145 degrees for 30 minutes and then reuse them??? In milk production, 145F for 30 minutes basically kills everything. I don't know the heat tolerance of the mask materials, but 150F is not all that hot?<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />

<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Speculation on reuse of n95 masks: Can you heat treat the masks at 145 degrees for 30 minutes and then reuse them??? In milk production, 145F for 30 minutes basically kills everything. I don't know the heat tolerance of the mask materials, but 150F is not all that hot?<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

<br />
== '''February 18, 2020:''' ==<br />
Continued call and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
Finally heard back from Bellingham Makerspace at EOD, I think this is our location... waiting for 100% confirmation... <br />
<br />
== '''February 17, 2020:''' ==<br />
Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />
<br />
D3D-U Extruder jamb for second time today... think its the retract settings, but not really sure.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />
<br />
Started printing corner brackets.<br />
<br />
Reworked CAD for Fablet case. Hope to have something to post and print tomorrow.<br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

<br />
Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />

== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Speculation on reuse of n95 masks: Can you heat treat the masks at 145 degrees for 30 minutes and then reuse them??? In milk production, 145F for 30 minutes basically kills everything. I don't know the heat tolerance of the mask materials, but 150F is not all that hot? <br />

G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />

He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />
<br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

<br />
Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />

<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />

Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

<div>#start a project. You start by editing a diagram, not the physical layout reality. That is called a schematic. the schematic is later converted into a physical layout.<br />
#Drag and drop components into the design<br />
#You must then connect them, and verify the design for connection errors.<br />
#Once you have the schematic, you can add physical reality to it. This consists of moving components around and rotating them in order to make the easiest connections. adding footprints for components and wire thicknesses. The footprints concept is that any component can come in various packages (or size/shape). We must specify exactly which package we are using.<br />

Support should be 2-point for parallelogramming (goes straight down) or 4 point for straight up-down - though 2-point parallelogramming should likewise produce straight up-down. See [[D3D Universal#Plotter]] pen holder design.<br />
<br />
==GcodePlot Extension Install==<br />
#Download .zip file from Github [https://github.com/arpruss/gcodeplot]<br />
##Save to an easy to access location i.e. home/downloads/<br />
#unzip the file in the above location i.e. home/downloads/gcodeplot-master<br />
#Navigate to the directory where the file is unzipped (above example is "home" and right click downloads -> open in terminal. <br />
# Terminal should show "username:~/Downloads$"<br />
#Type the following command in the terminal: <code>sudo cp -rv gcodeplot-master/* /usr/share/inkscape/extensions/</code> Press enter.<br />
##Basic explanation of above code: "sudo" = Super User Do, "cp"=copy command "-rv"=Options flags for the copy(r=recursive v-verbose(show output on screen)), "gcodeplot-master/*"=copy all files within gcodeplot-master, "/usr/share/inkscape/extensions/"=copy the files to this location. (More info easily found by Googling "Linux cp command" or typing "cp --help" in the console)<br />
#Terminal will request sudo password (this is the same password you use to log into OSE linux) - Character entry is not shown, so very carefully enter your password and hit enter.<br />
#You will see several lines appear, indicating that the files have been copied<br />
##The last few lines should look like the following:<br />
<pre>'gcodeplot-master/svgpath/path.py' -> '/usr/share/inkscape/extensions/svgpath/path.py'<br />
'gcodeplot-master/svgpath/shader.py' -> '/usr/share/inkscape/extensions/svgpath/shader.py'<br />
'gcodeplot-master/TODO' -> '/usr/share/inkscape/extensions/TODO'<br />
</pre><br />
#Close Inkscape if open<br />
#Open Inkscape, go to file->Save As, then verify in dropdown filetype selector that "3-axis gcode plotter (*.gcode)" is an option.<br />
#Installation now complete!<br />
<br />
==Instructions==<br />
From Instructable, in pertinent part, after installing extension:<br />
<br />
#Restart or start Inkscape.<br />
#Load the SVG file you want to draw or cut into Inskcape. The lower-left corner of the page in Inkscape corresponds to the minimum X and Y coordinates you measured in the previous step. Make sure your images fit into the print area.<br />
#Convert the drawing to a path: ctrl-A to select everything, then Path | Object to Path.<br />
#Save to gcode:<br />
##File | Save As...<br />
##Select: "3-axis gcode plotter" ... And a massive popup comes out. Should be self-explanatory, outside of:<br />
##'''Make the area SAME in document size as the X and Y in the output settings. Straightforward.'''<br />
<br />
==Exercise==<br />
#Get your hands on SVG files. Since there are more PNG than SVG available in the wild - convert PNG to SVG first with Inkscape - [https://www.dedoimedo.com/computers/convert-png-to-svg.html]<br />
#Take a file such as [[File:OSE_d3d_printer_logo_v1-16a.png|200px]]. But would need to convert it to vectors. Power user material.<br />
#So start with a vector file - [[File:Axis_Idler_LAI_SVGs.zip]]<br />
#Yes! Convert Object to Path in Path menu in inskscape<br />
#Export gcode.<br />
#How do you know g-code is valid? <s>Use [[OpenSCAM]] - see [https://www.norwegiancreations.com/2015/08/an-intro-to-g-code-and-how-to-generate-it-using-inkscape/]. To install a deb package, use a tool called [[gdebi]]. OpenSCAM installs under the name CAMotics. Didn't work on Ubuntu 16.04.</s> <br />
##Use https://ncviewer.com/ instead<br />
<br />
=MJ Notes=<br />
#Installed GcodePlot for Inkscape.<br />
#Drew in inkscape. Set coordinates the same in Save As Gcode and in Document/Settings for the document<br />
#Viewed the file in https://ncviewer.com/. Line I drew showed up, but not the text.<br />
<br />
=Inkscape Notes=<br />
*Work in File -> doc properties<br />
*In inskscape, make sure you have a correct image size<br />
*Work in mm'<br />
*Using a vector file, grab a corner to resize it correctly in mm<br />
*In path menu - select Trace Bitmap<br />
*Save SVG<br />
*Then it's ready for the Inkscape plugin called Gcode Tools<br />
*https://www.lifewire.com/inkscape-to-make-templates-cutting-machines-1701892 - turning letters into gcode with gcodetools - works for us<br />
*Add G29 and eliminate pen park in preprocessing for printing<br />
<br />
<br />
==Gcodeplot Settings==<br />
*Set z working height to 0<br />
*Make sure you are within 150 by 150 mm boundaries <br />
*Copy start gcode. from d3d universal on homing and leveling<br />
*See [[Jessica Log]]<br />
*From [[Don Log]]:<br />
Inkscape has many setting to review when exporting (save as) to gcode. The notable ones as follows:<br />
<br />
[[File:GcodePlotExportSettings.png]]<br />
<br />
- Precision setting should be set to 0.010 to correspond to the 10 microns of accuracy that the D3D printer is designed to achieve. <br />
- The left/right & upper/lower coordinate settings are very relevant to how the plotter arranges itself on the print bed. <br />
- Speed settings could be increased as high as 150 mm/s. NOTE: these speeds over-ride the speed settings which can manually be set on the marlin controller.<br />
<br />
==Sample Files==<br />
<br />
View these with [[NC Viewer]]<br />
*Don - Known good plotter file [[File:d3dUtextPlot.gcode.zip]]<br />
*Jessica - [[File:OESd4dStickpath4.zip]] -<br />
<br />
=Support=<br />
*It appears that the GcodePlot extension is not supported. See thread with some troubleshooting on proper install - [https://forum.inkscapecommunity.com/index.php?topic=1407.0]<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

== '''February 17, 2020:''' ==<br />
Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />
<br />

Started printing Angled Corners for D3D Pro. Learned a bit about removing scaffold and bed adhesion on D3D-U - Good adhesion printing directly onto buildtak on steel plate (preheat steel plate with heater, brim =5. Had to put plate in freezer to get release as large hammer and all the scrapers not effective. Spring steel plate adhesion great, so much so that plate warps = parts warped.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />
<br />
Started printing corner brackets.<br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />

Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

<hr />
<div>=Gcode Plot=<br />
<br />
#Video 1 - [https://www.youtube.com/watch?v=yrxhqW7BCf8]<br />
#GcodePlot extension for inkscape. Inkscape post - [https://inkscape.org/~arpruss/%E2%98%85gcodeplot]. Github - [https://github.com/arpruss/gcodeplot]. Instructable - [https://www.instructables.com/id/Use-3D-Printer-As-a-Plottercutter/]<br />
#Pen holder 3D design - [https://www.thingiverse.com/thing:1873991]. Simplest way - is a flat piece of plastic. Support should be 2-point for parallelogramming (goes straight down) or 4 point for straight up-down - though 2-point parallelogramming should likewise produce straight up-down. See [[D3D Universal#Plotter]] pen holder design.<br />
<br />
==GcodePlot Extension Install==<br />
#Download .zip file from Github [https://github.com/arpruss/gcodeplot]<br />
##Save to an easy to access location i.e. home/downloads/<br />
#unzip the file in the above location i.e. home/downloads/gcodeplot-master<br />
#Navigate to the directory where the file is unzipped (above example is "home" and right click downloads -> open in terminal. <br />
# Terminal should show "username:~/Downloads$"<br />
#Type the following command in the terminal: <code>sudo cp -rv gcodeplot-master/* /usr/share/inkscape/extensions/</code> Press enter.<br />
##Basic explanation of above code: "sudo" = Super User Do, "cp"=copy command "-rv"=Options flags for the copy(r=recursive v-verbose(show output on screen)), "gcodeplot-master/*"=copy all files within gcodeplot-master, "/usr/share/inkscape/extensions/"=copy the files to this location. (More info easily found by Googling "Linux cp command" or typing "cp --help" in the console)<br />
#Terminal will request sudo password (this is the same password you use to log into OSE linux) - Character entry is not shown, so very carefully enter your password and hit enter.<br />
#You will see several lines appear, indicating that the files have been copied<br />
##i.e. <br />
<pre>'gcodeplot-master/svgpath/path.py' -> '/usr/share/inkscape/extensions/svgpath/path.py'<br />
'gcodeplot-master/svgpath/shader.py' -> '/usr/share/inkscape/extensions/svgpath/shader.py'<br />
'gcodeplot-master/TODO' -> '/usr/share/inkscape/extensions/TODO'<br />
</pre><br />
#Close Inkscape if open<br />
#Open Inkscape, go to file->Save As, then verify in dropdown filetype selector that "3-axis gcode plotter (*.gcode)" is an option.<br />
#Installation now complete!<br />
<br />
<br />
<br />
==Instructions==<br />
From Instructable, in pertinent part, after installing extension:<br />
<br />
#Restart or start Inkscape.<br />
#Load the SVG file you want to draw or cut into Inskcape. The lower-left corner of the page in Inkscape corresponds to the minimum X and Y coordinates you measured in the previous step. Make sure your images fit into the print area.<br />
#Convert the drawing to a path: ctrl-A to select everything, then Path | Object to Path.<br />
#Save to gcode:<br />
##File | Save As...<br />
##Select: "3-axis gcode plotter" ... And a massive popup comes out. Should be self-explanatory, outside of:<br />
##'''Make the area SAME in document size as the X and Y in the output settings. Straightforward.'''<br />
<br />
==Exercise==<br />
#Get your hands on SVG files. Since there are more PNG than SVG available in the wild - convert PNG to SVG first with Inkscape - [https://www.dedoimedo.com/computers/convert-png-to-svg.html]<br />
#Take a file such as [[File:OSE_d3d_printer_logo_v1-16a.png|200px]]. But would need to convert it to vectors. Power user material.<br />
#So start with a vector file - [[File:Axis_Idler_LAI_SVGs.zip]]<br />
#Yes! Convert Object to Path in Path menu in inskscape<br />
#Export gcode.<br />
#How do you know g-code is valid? <s>Use [[OpenSCAM]] - see [https://www.norwegiancreations.com/2015/08/an-intro-to-g-code-and-how-to-generate-it-using-inkscape/]. To install a deb package, use a tool called [[gdebi]]. OpenSCAM installs under the name CAMotics. Didn't work on Ubuntu 16.04.</s> <br />
##Use https://ncviewer.com/ instead<br />

=Inkscape Notes=<br />
*Work in File -> doc properties<br />
*In inskscape, make sure you have a correct image size<br />
*Work in mm'<br />
*Using a vector file, grab a corner to resize it correctly in mm<br />
*In path menu - select Trace Bitmap<br />
*Save SVG<br />
*Then it's ready for the Inkscape plugin called Gcode Tools<br />
*https://www.lifewire.com/inkscape-to-make-templates-cutting-machines-1701892 - turning letters into gcode with gcodetools - works for us<br />
*Add G29 and eliminate pen park in preprocessing for printing<br />
<br />
<br />
==Gcodeplot Settings==<br />
*Set z working height to 0<br />
*Make sure you are within 150 by 150 mm boundaries <br />
*Copy start gcode. from d3d universal on homing and leveling<br />
*See [[Jessica Log]]<br />
*From [[Don Log]]:<br />
Inkscape has many setting to review when exporting (save as) to gcode. The notable ones as follows:<br />
<br />
[[File:GcodePlotExportSettings.png]]<br />
<br />
- Precision setting should be set to 0.010 to correspond to the 10 microns of accuracy that the D3D printer is designed to achieve. <br />
- The left/right & upper/lower coordinate settings are very relevant to how the plotter arranges itself on the print bed. <br />
- Speed settings could be increased as high as 150 mm/s. NOTE: these speeds over-ride the speed settings which can manually be set on the marlin controller.<br />
<br />
==Sample Files==<br />

View these with [[NC Viewer]]<br />
*Don - Known good plotter file [[File:d3dUtextPlot.gcode.zip]]<br />
*Jessica - [[File:OESd4dStickpath4.zip]] -<br />

=Support=<br />
*It appears that the GcodePlot extension is not supported. See thread with some troubleshooting on proper install - [https://forum.inkscapecommunity.com/index.php?topic=1407.0]<br />

;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />

<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />

<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />

<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

<br />
=Software=<br />
<br />
== Android options ==<br />
Industrial Android on rPi: https://emteria.com/<br />
Not sure it might be NC, or maybe that's just the service layer they are selling on top of what seems to be mostly a business use case<br />
<br />
Also trying other Android Options:<br />
*LineageOS (formerly Cyanogenmod): https://konstakang.com/devices/rpi3/LineageOS15.1/<br />
*Android for RPi: https://www.makeuseof.com/tag/install-android-raspberry-pi/<br />
<br />
<br />
<br />
== Keyboard options ==<br />
Note: Best touchscreen keyboard application on the Raspbian so far is Florence<br />
<br><br />
> sudo apt-get install florence<br />
<br />
<br><br />
Also trying several other linux on screen keyboard options while building android images to try:<br />
* GOK (GNOME Onscreen Keyboard)<br />
* kvkbd <br />
* onboard<br />
* Florence<br />
<br />
== Raspbian installation ==<br />
Based on the NOOBS install: https://www.raspberrypi.org/downloads/noobs/<br />
<br />
SD card must be FAT formatted, at least 8GB and preferably 16GB:<br />
https://www.raspberrypi.org/documentation/installation/noobs.md<br />
<br />
It's handy to have a usb keyboard and mouse to navigate the install process once the prepared SD card is on the rPi.<br />
<br />
== Cura ==<br />
<br />
I had issues trying to run Cura on the Raspbian, it kept crashing. It seems like someone has compiled a version and posted it in the ultimaker forums that will run on the RPi processor:<br />
https://community.ultimaker.com/topic/28746-experimental-cura-build-for-raspberry-pi-4-now-available/<br />
<br />
Downloads:<br />
https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0<br />
<br />
Install procedure:<br />
Once the appimage file is downloaded (I used Cura-mb-master-armhf-20191209.AppImage), make the file executable<br />
<br><br />
> chmod +x Cura-mb-master-armhf-20191209.AppImage<br />
<br />
Then you just need to run the app image file:<br />
<br><br />
> ./Cura-mb-master-armhf-20191209.AppImage<br />
<br />
== Camera ==<br />
From https://projects.raspberrypi.org/en/projects/getting-started-with-picamera/3<br />
<br />
Once it's plugged in, Camera just needs to be toggled on in the config -> "interfaces"<br />
<br />
Once restarted, you can take a picture like this:<br><br />
> raspistill -o Desktop/image.jpg<br />
<br />
This will activate the camera module and show a view finder, until you hit "Enter" and it saves a picture to the specified location.<br />
<br />
== Screen ==<br />
What resolution works best for the screen? The directions that came with the screen result in unused pixels on left and right side.<br />
<br />
From Product Sheet: <br />
*Native Resolution is 1024 x 600.<br />
*Power Consumption 800mA @ 5v<br />
<br />
Product Sheet instructions for /boot/config.txt:<br />
*In terminal "sudo nano /boot/config.txt"<br />
*Comment out "dtoverlay=vc4-fkms-vd3" and "max_framebuffers=2"<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />
<br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />

G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />
<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />

Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />

<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />

Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

==Printer Extruder==<br />
<br />
{{Hint|Note the small extruder gear shown is MK8- we are using an MK7. '''Note''': Supervolcano nozzle has heat transfer issues, so we are using a 3 mm E3D v6 heat break with success (6mm threads on both sides - note that E3D v6 has 6 mm on the nozzle side, 7 mm on the cold side. Can also test Titan Aero v6 1.75 mm - which appears to have 6 mm thread on both sides. 3mm titan aero is definitely 6 mm thread on each side: see [[E3D_Titan_Aero_Extruder#CAD]]}}<br />
<br />
'''Notes''': Still missing from final assembly by MJ: fan, heat sink heat exchanger, MK7 gear, spring. In final CAD of extruder assy, heat break does not stick out of the heat sink. In reality, it sticks out about 3 mm. Where is the discrepancy if the heat break is 25 mm long?<br />

==Printer Extruder==<br />
<br />
{{Hint|Note the small extruder gear shown is MK8- we are using an MK7. '''Note''': Supervolcano nozzle has heat transfer issues, so we are using a 3 mm E3D v6 heat break with success (6mm threads on both sides - note that E3D v6 has 6 mm on the nozzle side, 7 mm on the cold side. Can also test Titan Aero v6 1.75 mm - which appears to have 6 mm thread on both sides. 3mm titan aero is definitely 6 mm thread on each side: see [[E3D_Titan_Aero_Extruder#CAD]]}}<br />
<br />
'''Notes''': Still missing from final assembly by MJ: fan, heat sink heat exchanger, MK7 gear, spring. In final CAD of extruder assy, heat break does not stick out of the heat sink. In reality, it sticks out about 3 mm. Where is the discrepancy if the heat break is 25 mm long?<br />

Packed tools, parts etc. Notified around 5pm that Adrian cannot make it. Cancelled our event at BMS.<br />
<br />
== '''Thur Mar 12:''' ==<br />
Checked parts and repacked kits. Packing up tools and other items. Continue to print off parts for BMS printer. <br />
<br />
== '''Wed Mar 11:''' ==<br />
Make backup plan for parts for BMS. Print control panel and rest of parts for D3D U. Emails. Moved Curriculum [[March 2020 STEAM Camp]] to OSE March STEAM Camp Curriculum - [https://docs.google.com/presentation/d/1OUiz7H8DRKdV497120-AwlSH81FoyKfu9EV42AuVexw/edit?usp=sharing Working Doc]. Updated PiFablet USB wiring plan and posted photo.<br />
<br />
== '''Tue Mar 10:''' ==<br />
Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />

<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />

Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

<br />
Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />

*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />

Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

==Printer Extruder==<br />
<br />
{{Hint|Note the small extruder gear shown is MK8- we are using an MK7. '''Note''': Supervolcano nozzle has heat transfer issues, so we are using a 3 mm E3D v6 heat break with success (6mm threads on both sides - note that E3D v6 has 6 mm on the nozzle side, 7 mm on the cold side. Can also test Titan Aero v6 1.75 mm - which appears to have 6 mm thread on both sides. 3mm titan aero is definitely 6 mm thread on each side: see [[E3D_Titan_Aero_Extruder#CAD]]}}<br />
<br />
'''Notes''': Still missing from final assembly by MJ: fan, heat sink heat exchanger, MK7 gear, spring. In final CAD of extruder assy, heat break does not stick out of the heat sink. In reality, it sticks out about 3 mm. Where is the discrepancy if the heat break is 25 mm long?<br />

#Create quick attach circuit board holder for D3D-U - to use when milling<br />
#Create "shadow board" graphic for rapid verification of parts kits (ideally generated via a BOM sheet somehow - Research)<br />
<br />
== '''Fri Mar 13:''' ==<br />
<br />
== '''Thur Mar 12:''' ==<br />
Checked parts and repacked kits. Packing up tools and other items. Continue to print off parts for BMS printer. <br />
<br />
== '''Wed Mar 11:''' ==<br />
Make backup plan for parts for BMS. Print control panel and rest of parts for D3D U. Emails. Moved Curriculum [[March 2020 STEAM Camp]] to OSE March STEAM Camp Curriculum - [https://docs.google.com/presentation/d/1OUiz7H8DRKdV497120-AwlSH81FoyKfu9EV42AuVexw/edit?usp=sharing Working Doc]. Updated PiFablet USB wiring plan and posted photo.<br />
<br />
== '''Tue Mar 10:''' ==<br />
Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes. (Perhaps try [[Pica Brand Marking Tools]] expensive but altrafine, and grease pencil may be optimal for etchant protection? - [[User: Eric]])<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

<br />
== '''February 18, 2020:''' ==<br />
Continued call and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
Finally heard back from Bellingham Makerspace at EOD, I think this is our location... waiting for 100% confirmation... <br />
<br />
== '''February 17, 2020:''' ==<br />
Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />
<br />
D3D-U Extruder jamb for second time today... think its the retract settings, but not really sure.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />

M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

<br />
Finally heard back from Bellingham Makerspace at EOD, I think this is our location... waiting for 100% confirmation... <br />
<br />
== '''February 17, 2020:''' ==<br />
Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />

Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

=Narrative=<br />
From website posting, we have a narrative:<br />
<br />
What are the critical tools that we need for effective collaborative design? These tools involve, first and foremost – Collaborative Literacy – a mindset and a practical process – that enables people to work together for the common good. Beyond these soft skills is a set of hard skills and interdisciplinary technical knowledge that enables one to come up with creative and effective design.<br />
<br />
=='''On the first day:'''==<br />
#we provide an introduction to Open Source Ecology and collaborative design – for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to transform the world’s economy from proprietary to collaborative – with an accompanying cascade of positive change throughout the world. 1 hour.<br />
#We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program.<br />
<br />
=='''On the second day – we dive into the design aspect:'''==<br />
#a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you’ll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
#The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them – or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer. <br />
#Generating control code by hand with a super-basic lesson on g-code generation. This is useful whenever you want custom operation, whenever software for the specific task you need is not available, or whenever you are doing something so simple that it's easier to generate code by hand.<br />
#Generate control code using software such as Inkscape, or FreeCAD. These can be used for drawings or to generate tool paths for your plotter or CNC hole drill. <br />
#Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
#Simple exercise - draw something simple in Inkscape, and convert it to a plot while doing Marlin-based auto leveling.This kind of workflow is important because you can use it for many different purposes: a vinyl cutter, a CNC torch table with automatic leveling + operator adjustment.<br />
#Flow of Day 2: start with designing something basic for a 5 minute print job - of a bit holder. Move into Inkscape and plotting, with insights of how to use the plotter for drawing, printing cutting patterns onto a metal substrate, and circuit plotting. The idea here is to master digital control of 2-dimensional motion, which serves as a basic for multiaxis machining - such as with a screw machine<br />
#Last task: set up a print at the end of the day for the CNC Drill Attachment.<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro – using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
=='''On the third day – we move on to electronics'''==<br />
#Aand make more fabrication tools while we are at it! We start with 3D CAD to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. <br />
#Then we will use the CNC pen plotter that we built on Day 2 – to plot circuits on copper-clad board. We can use Inkscape to do this. Or we can use KiCad. Or we can draw the circuit by hand. We will then etch this circuit in a bath...<br />
#and then CNC drill holes in it so we produce a circuit board. <br />
#We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. <br />
#We will then use this controller to switch large loads using a solid state relay...<br />
#...to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device – demonstrating that we have the power to control kilowatts of electrical power automatically – using a microcontroller that we built ourselves – using a 3D printer and plotter that we made together from scratch. <br />
#We will learn how to produce the circuit design in KiCad open source electronics software, <br />
#and how to export files for circuit plotting and drilling from KiCad – so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
Flow of day: learning basics about circuits - why and where they are important - and how to go about making a circuit if you need one in your project. Kicad, Inkscape, and manual generation of files. CNC hole drilling.<br />
<br />
==On the fourth day – we move on to the Pi Fablet==<br />
A computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up – and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die – because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz.

==Narrative Summary==<br />
===Day 1===<br />
<br />
On the first day – we provide an introduction to Open Source Ecology and collaborative design - for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to tranform the world’s economy from proprietary to collaboratve – with an accompanying cascade of positive change throughout the world. We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program. <br />
<br />
===Day 2===<br />
<br />
On the second day, we dive into the design aspect – with a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you'll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
<br />
The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them - or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer – by uploading new software, generating control code by hand, or using software such as Inkscape, KiCad, or FreeCAD to generate tool paths for your plotter or mill. Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro - using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
===Day 3===<br />
On day 3, we move on to electronics - and make more fabrication tools while we are at it! We start with 3D design to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. Then we will use the CNC pen plotter that we built on Day 2 - to plot circuits on copper-clad board. We will then etch this circuit in a bath, and then CNC drill holes in it so we produce a circuit board. We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. We will then use this controller to switch large loads using a solid state relay to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device - demonstrating that we have the power to control kilowatts of electrical power automatically - using a microcontroller that we built ourselves - using a 3D printer and plotter that we made together from scratch. We will learn how to produce the circuit design in KiCad open source electronics software, and how to export files for circuit plotting and drilling from KiCad - so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
===Day 4===<br />
<br />
On the 4th day, we move on to the OSE Pi Fablet - a computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up - and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die - because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill.<br />
<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />
#Day 2: Printer Calibrations: Retraction calibration; filament feed calibration; perpendicular (skew) calibration; alignment of head parallel to bed and data point collection; how to modify menu to say My Name D3D Universal. <br />
#Day 3: KiCad lesson: KiCad Arduino stripboard - make a proper PCB - plot and drill.<br />
<br />
##KiCad workflow overview. Setup of project and KiCad interface. What version of KiCad to use for OSE and how to install it.<br />
##How to draw a schematic by starting with a voltage source, wire connections, an SSR, and a load such as a lightbulb.<br />
##How to insert more complex components - the 328p chip example<br />
##How to add through holes that will be turned into a drilling file<br />
##How to export a schematic<br />
##How to produce and export a layout<br />
##How to produce and export a CAM file (gerber). Is there any other alternatives here?<br />
##How to import the design into FreeCAD<br />
##How to generate toolpath for Marlin, either via FreeCAD or FlatCam.<br />

<br />
=Narrative=<br />
From website posting, we have a narrative:<br />
<br />
What are the critical tools that we need for effective collaborative design? These tools involve, first and foremost – Collaborative Literacy – a mindset and a practical process – that enables people to work together for the common good. Beyond these soft skills is a set of hard skills and interdisciplinary technical knowledge that enables one to come up with creative and effective design.<br />
<br />
=='''On the first day:'''==<br />
#we provide an introduction to Open Source Ecology and collaborative design – for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to transform the world’s economy from proprietary to collaborative – with an accompanying cascade of positive change throughout the world. 1 hour.<br />
#We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program.<br />
<br />
=='''On the second day – we dive into the design aspect:'''==<br />
#a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you’ll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
#The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them – or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer. <br />
#Generating control code by hand with a super-basic lesson on g-code generation. This is useful whenever you want custom operation, whenever software for the specific task you need is not available, or whenever you are doing something so simple that it's easier to generate code by hand.<br />
#Generate control code using software such as Inkscape, or FreeCAD. These can be used for drawings or to generate tool paths for your plotter or CNC hole drill. <br />
#Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
#Simple exercise - draw something simple in Inkscape, and convert it to a plot while doing Marlin-based auto leveling.This kind of workflow is important because you can use it for many different purposes: a vinyl cutter, a CNC torch table with automatic leveling + operator adjustment.<br />
#Flow of Day 2: start with designing something basic for a 5 minute print job - of a bit holder. Move into Inkscape and plotting, with insights of how to use the plotter for drawing, printing cutting patterns onto a metal substrate, and circuit plotting. The idea here is to master digital control of 2-dimensional motion, which serves as a basic for multiaxis machining - such as with a screw machine<br />
#Last task: set up a print at the end of the day for the CNC Drill Attachment.<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro – using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
=='''On the third day – we move on to electronics'''==<br />
#Aand make more fabrication tools while we are at it! We start with 3D CAD to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. <br />
#Then we will use the CNC pen plotter that we built on Day 2 – to plot circuits on copper-clad board. We can use Inkscape to do this. Or we can use KiCad. Or we can draw the circuit by hand. We will then etch this circuit in a bath...<br />
#and then CNC drill holes in it so we produce a circuit board. <br />
#We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. <br />
#We will then use this controller to switch large loads using a solid state relay...<br />
#...to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device – demonstrating that we have the power to control kilowatts of electrical power automatically – using a microcontroller that we built ourselves – using a 3D printer and plotter that we made together from scratch. <br />
#We will learn how to produce the circuit design in KiCad open source electronics software, <br />
#and how to export files for circuit plotting and drilling from KiCad – so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
Flow of day: learning basics about circuits - why and where they are important - and how to go about making a circuit if you need one in your project. Kicad, Inkscape, and manual generation of files. CNC hole drilling.<br />
<br />
==On the fourth day – we move on to the Pi Fablet==<br />
A computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up – and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die – because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill. We will use a Raspberry Pi 4B quad core 1.5 ghz wuth 4GB RAM – a powerful base for a practical tablet. We are including a 7″ touch screen, a Camera v2 8 megapixel module capable of 4000 pixel horizontal resolution (4K) to work with, and a battery pack. These parts are all included in the STEAM Camp admission.<br />

The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro - using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
===Day 3===<br />
On day 3, we move on to electronics - and make more fabrication tools while we are at it! We start with 3D design to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. Then we will use the CNC pen plotter that we built on Day 2 - to plot circuits on copper-clad board. We will then etch this circuit in a bath, and then CNC drill holes in it so we produce a circuit board. We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. We will then use this controller to switch large loads using a solid state relay to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device - demonstrating that we have the power to control kilowatts of electrical power automatically - using a microcontroller that we built ourselves - using a 3D printer and plotter that we made together from scratch. We will learn how to produce the circuit design in KiCad open source electronics software, and how to export files for circuit plotting and drilling from KiCad - so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
===Day 4===<br />
<br />
On the 4th day, we move on to the OSE Pi Fablet - a computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up - and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die - because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill.<br />
<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />
#Day 2: Printer Calibrations: Retraction calibration; filament feed calibration; perpendicular (skew) calibration; alignment of head parallel to bed and data point collection; how to modify menu to say My Name D3D Universal. <br />
#Day 3: KiCad lesson: KiCad Arduino stripboard - make a proper PCB - plot and drill.<br />

==Day 4:== <br />
Raspberry Pi Tablet - Build of Fablet with camera + 3D Printed Case +[[Off The Shelf Bat Pack]]. Programming lesson for a Camera App.<br />
<br />
=Narrative=<br />
From website posting, we have a narrative:<br />
<br />
What are the critical tools that we need for effective collaborative design? These tools involve, first and foremost – Collaborative Literacy – a mindset and a practical process – that enables people to work together for the common good. Beyond these soft skills is a set of hard skills and interdisciplinary technical knowledge that enables one to come up with creative and effective design.<br />
<br />
=='''On the first day:'''==<br />
#we provide an introduction to Open Source Ecology and collaborative design – for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to transform the world’s economy from proprietary to collaborative – with an accompanying cascade of positive change throughout the world. 1 hour.<br />
#We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program.<br />
<br />
=='''On the second day – we dive into the design aspect:'''==<br />
#a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you’ll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
#The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them – or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer. <br />
#Generating control code by hand with a super-basic lesson on g-code generation. This is useful whenever you want custom operation, whenever software for the specific task you need is not available, or whenever you are doing something so simple that it's easier to generate code by hand.<br />
#Generate control code using software such as Inkscape, or FreeCAD. These can be used for drawings or to generate tool paths for your plotter or CNC hole drill. <br />
#Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
#Simple exercise - draw something simple in Inkscape, and convert it to a plot while doing Marlin-based auto leveling.This kind of workflow is important because you can use it for many different purposes: a vinyl cutter, a CNC torch table with automatic leveling + operator adjustment.<br />
#Flow of Day 2: start with designing something basic for a 5 minute print job - of a bit holder. Move into Inkscape and plotting, with insights of how to use the plotter for drawing, printing cutting patterns onto a metal substrate, and circuit plotting. The idea here is to master digital control of 2-dimensional motion, which serves as a basic for multiaxis machining - such as with a screw machine<br />
#Last task: set up a print at the end of the day for the CNC Drill Attachment.<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro – using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
=='''On the third day – we move on to electronics'''==<br />
#Aand make more fabrication tools while we are at it! We start with 3D CAD to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. <br />
#Then we will use the CNC pen plotter that we built on Day 2 – to plot circuits on copper-clad board. We can use Inkscape to do this. Or we can use KiCad. Or we can draw the circuit by hand. We will then etch this circuit in a bath...<br />
#and then CNC drill holes in it so we produce a circuit board. <br />
#We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. <br />
#We will then use this controller to switch large loads using a solid state relay...<br />
#...to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device – demonstrating that we have the power to control kilowatts of electrical power automatically – using a microcontroller that we built ourselves – using a 3D printer and plotter that we made together from scratch. <br />
#We will learn how to produce the circuit design in KiCad open source electronics software, <br />
#and how to export files for circuit plotting and drilling from KiCad – so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
Flow of day: learning basics about circuits - why and where they are important - and how to go about making a circuit if you need one in your project. Kicad, Inkscape, and manual generation of files. CNC hole drilling.<br />
<br />
==On the fourth day – we move on to the Pi Fablet==<br />
A computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up – and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die – because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill. We will use a Raspberry Pi 4B quad core 1.5 ghz wuth 4GB RAM – a powerful base for a practical tablet. We are including a 7″ touch screen, a Camera v2 8 megapixel module capable of 4000 pixel horizontal resolution (4K) to work with, and a battery pack. These parts are all included in the STEAM Camp admission.<br />
<br />

==Narrative Summary==<br />
===Day 1===<br />
<br />
On the first day – we provide an introduction to Open Source Ecology and collaborative design - for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to tranform the world’s economy from proprietary to collaboratve – with an accompanying cascade of positive change throughout the world. We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch.

This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill.<br />
<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />

<br />
<br />
=Narrative=<br />
From website posting, we have a narrative:<br />
<br />
What are the critical tools that we need for effective collaborative design? These tools involve, first and foremost – Collaborative Literacy – a mindset and a practical process – that enables people to work together for the common good. Beyond these soft skills is a set of hard skills and interdisciplinary technical knowledge that enables one to come up with creative and effective design.<br />
<br />
=='''On the first day:'''==<br />
#we provide an introduction to Open Source Ecology and collaborative design – for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to transform the world’s economy from proprietary to collaborative – with an accompanying cascade of positive change throughout the world. 1 hour.<br />
#We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program.<br />
<br />
=='''On the second day – we dive into the design aspect:'''==<br />
#a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you’ll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
#The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them – or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer. <br />
#Generating control code by hand with a super-basic lesson on g-code generation. This is useful whenever you want custom operation, whenever software for the specific task you need is not available, or whenever you are doing something so simple that it's easier to generate code by hand.<br />
#Generate control code using software such as Inkscape, or FreeCAD. These can be used for drawings or to generate tool paths for your plotter or CNC hole drill. <br />
#Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
#Simple exercise - draw something simple in Inkscape, and convert it to a plot while doing Marlin-based auto leveling.This kind of workflow is important because you can use it for many different purposes: a vinyl cutter, a CNC torch table with automatic leveling + operator adjustment.<br />
#Flow of Day 2: start with designing something basic for a 5 minute print job - of a bit holder. Move into Inkscape and plotting, with insights of how to use the plotter for drawing, printing cutting patterns onto a metal substrate, and circuit plotting. The idea here is to master digital control of 2-dimensional motion, which serves as a basic for multiaxis machining - such as with a screw machine<br />
#Last task: set up a print at the end of the day for the CNC Drill Attachment.<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro – using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
=='''On the third day – we move on to electronics'''==<br />
#Aand make more fabrication tools while we are at it! We start with 3D CAD to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. <br />
#Then we will use the CNC pen plotter that we built on Day 2 – to plot circuits on copper-clad board. We can use Inkscape to do this. Or we can use KiCad. Or we can draw the circuit by hand. We will then etch this circuit in a bath...<br />
#and then CNC drill holes in it so we produce a circuit board. <br />
#We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. <br />
#We will then use this controller to switch large loads using a solid state relay...<br />
#...to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device – demonstrating that we have the power to control kilowatts of electrical power automatically – using a microcontroller that we built ourselves – using a 3D printer and plotter that we made together from scratch. <br />
#We will learn how to produce the circuit design in KiCad open source electronics software, <br />
#and how to export files for circuit plotting and drilling from KiCad – so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
Flow of day: learning basics about circuits - why and where they are important - and how to go about making a circuit if you need one in your project. Kicad, Inkscape, and manual generation of files. CNC hole drilling.<br />
<br />
==On the fourth day – we move on to the Pi Fablet==<br />
A computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up – and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die – because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill. We will use a Raspberry Pi 4B quad core 1.5 ghz wuth 4GB RAM – a powerful base for a practical tablet. We are including a 7″ touch screen, a Camera v2 8 megapixel module capable of 4000 pixel horizontal resolution (4K) to work with, and a battery pack. These parts are all included in the STEAM Camp admission.<br />
<br />
<br />

===Day 1===<br />
<br />
On the first day – we provide an introduction to Open Source Ecology and collaborative design - for a transparent and inclusive economy of abundance.

This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill.<br />
<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />
#Day 2: Printer Calibrations: Retraction calibration; filament feed calibration; perpendicular (skew) calibration; alignment of head parallel to bed and data point collection; how to modify menu to say My Name D3D Universal. <br />
#Day 3: KiCad lesson: KiCad Arduino stripboard - make a proper PCB - plot and drill.<br />
<br />
##KiCad workflow overview. Setup of project and KiCad interface. What version of KiCad to use for OSE and how to install it.<br />
##How to draw a schematic by starting with a voltage source, wire connections, an SSR, and a load such as a lightbulb.<br />
##How to insert more complex components - the 328p chip example<br />
##How to add through holes that will be turned into a drilling file<br />
##How to export a schematic<br />
##How to produce and export a layout<br />
##How to produce and export a CAM file (gerber). Is there any other alternatives here?<br />
##How to import the design into FreeCAD<br />
##How to generate toolpath for Marlin, either via FreeCAD or FlatCam.<br />

Raspberry Pi Tablet - Build of Fablet with camera + 3D Printed Case +[[Off The Shelf Bat Pack]]. Programming lesson for a Camera App. <br />
<br />
<br />
=Narrative=<br />
From website posting, we have a narrative:<br />
<br />
What are the critical tools that we need for effective collaborative design? These tools involve, first and foremost – Collaborative Literacy – a mindset and a practical process – that enables people to work together for the common good. Beyond these soft skills is a set of hard skills and interdisciplinary technical knowledge that enables one to come up with creative and effective design.<br />
<br />
=='''On the first day:'''==<br />
#we provide an introduction to Open Source Ecology and collaborative design – for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to transform the world’s economy from proprietary to collaborative – with an accompanying cascade of positive change throughout the world. 1 hour.<br />
#We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program.<br />
<br />
=='''On the second day – we dive into the design aspect:'''==<br />
#a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you’ll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
#The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them – or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer. <br />
#Generating control code by hand with a super-basic lesson on g-code generation. This is useful whenever you want custom operation, whenever software for the specific task you need is not available, or whenever you are doing something so simple that it's easier to generate code by hand.<br />
#Generate control code using software such as Inkscape, or FreeCAD. These can be used for drawings or to generate tool paths for your plotter or CNC hole drill. <br />
#Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
#Simple exercise - draw something simple in Inkscape, and convert it to a plot while doing Marlin-based auto leveling.This kind of workflow is important because you can use it for many different purposes: a vinyl cutter, a CNC torch table with automatic leveling + operator adjustment.<br />
#Flow of Day 2: start with designing something basic for a 5 minute print job - of a bit holder. Move into Inkscape and plotting, with insights of how to use the plotter for drawing, printing cutting patterns onto a metal substrate, and circuit plotting. The idea here is to master digital control of 2-dimensional motion, which serves as a basic for multiaxis machining - such as with a screw machine<br />
#Last task: set up a print at the end of the day for the CNC Drill Attachment.<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro – using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
=='''On the third day – we move on to electronics'''==<br />
#Aand make more fabrication tools while we are at it! We start with 3D CAD to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. <br />
#Then we will use the CNC pen plotter that we built on Day 2 – to plot circuits on copper-clad board. We can use Inkscape to do this. Or we can use KiCad. Or we can draw the circuit by hand. We will then etch this circuit in a bath...<br />
#and then CNC drill holes in it so we produce a circuit board. <br />
#We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. <br />
#We will then use this controller to switch large loads using a solid state relay...<br />
#...to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device – demonstrating that we have the power to control kilowatts of electrical power automatically – using a microcontroller that we built ourselves – using a 3D printer and plotter that we made together from scratch. <br />
#We will learn how to produce the circuit design in KiCad open source electronics software, <br />
#and how to export files for circuit plotting and drilling from KiCad – so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
Flow of day: learning basics about circuits - why and where they are important - and how to go about making a circuit if you need one in your project. Kicad, Inkscape, and manual generation of files. CNC hole drilling.<br />
<br />
==On the fourth day – we move on to the Pi Fablet==<br />
A computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up – and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die – because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill. We will use a Raspberry Pi 4B quad core 1.5 ghz wuth 4GB RAM – a powerful base for a practical tablet. We are including a 7″ touch screen, a Camera v2 8 megapixel module capable of 4000 pixel horizontal resolution (4K) to work with, and a battery pack. These parts are all included in the STEAM Camp admission.<br />
<br />
<br />

==Narrative Summary==<br />
===Day 1===<br />
<br />
On the first day – we provide an introduction to Open Source Ecology and collaborative design - for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to tranform the world’s economy from proprietary to collaboratve – with an accompanying cascade of positive change throughout the world. We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program. <br />

The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them - or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer – by uploading new software, generating control code by hand, or using software such as Inkscape, KiCad, or FreeCAD to generate tool paths for your plotter or mill. Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />

<br />
===Day 4===<br />
<br />
On the 4th day, we move on to the OSE Pi Fablet - a computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up - and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world.

This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill.<br />
<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />
#Day 2: Printer Calibrations: Retraction calibration; filament feed calibration; perpendicular (skew) calibration; alignment of head parallel to bed and data point collection; how to modify menu to say My Name D3D Universal. <br />
#Day 3: KiCad lesson: KiCad Arduino stripboard - make a proper PCB - plot and drill.<br />
<br />
##KiCad workflow overview. Setup of project and KiCad interface. What version of KiCad to use for OSE and how to install it.<br />
##How to draw a schematic by starting with a voltage source, wire connections, an SSR, and a load such as a lightbulb.<br />
##How to insert more complex components - the 328p chip example<br />
##How to add through holes that will be turned into a drilling file<br />
##How to export a schematic<br />
##How to produce and export a layout<br />
##How to produce and export a CAM file (gerber). Is there any other alternatives here?<br />
##How to import the design into FreeCAD<br />
##How to generate toolpath for Marlin, either via FreeCAD or FlatCam.<br />

#The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them – or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer. <br />
#Generating control code by hand with a super-basic lesson on g-code generation. This is useful whenever you want custom operation, whenever software for the specific task you need is not available, or whenever you are doing something so simple that it's easier to generate code by hand.<br />
#Generate control code using software such as Inkscape, or FreeCAD. These can be used for drawings or to generate tool paths for your plotter or CNC hole drill. <br />
#Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
#Simple exercise - draw something simple in Inkscape, and convert it to a plot while doing Marlin-based auto leveling.This kind of workflow is important because you can use it for many different purposes: a vinyl cutter, a CNC torch table with automatic leveling + operator adjustment.<br />
#Flow of Day 2: start with designing something basic for a 5 minute print job - of a bit holder. Move into Inkscape and plotting, with insights of how to use the plotter for drawing, printing cutting patterns onto a metal substrate, and circuit plotting. The idea here is to master digital control of 2-dimensional motion, which serves as a basic for multiaxis machining - such as with a screw machine<br />
#Last task: set up a print at the end of the day for the CNC Drill Attachment.<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro – using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
=='''On the third day – we move on to electronics'''==<br />
#Aand make more fabrication tools while we are at it! We start with 3D CAD to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. <br />
#Then we will use the CNC pen plotter that we built on Day 2 – to plot circuits on copper-clad board. We can use Inkscape to do this. Or we can use KiCad. Or we can draw the circuit by hand. We will then etch this circuit in a bath...<br />
#and then CNC drill holes in it so we produce a circuit board. <br />
#We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. <br />
#We will then use this controller to switch large loads using a solid state relay...<br />
#...to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device – demonstrating that we have the power to control kilowatts of electrical power automatically – using a microcontroller that we built ourselves – using a 3D printer and plotter that we made together from scratch. <br />
#We will learn how to produce the circuit design in KiCad open source electronics software, <br />
#and how to export files for circuit plotting and drilling from KiCad – so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
Flow of day: learning basics about circuits - why and where they are important - and how to go about making a circuit if you need one in your project. Kicad, Inkscape, and manual generation of files. CNC hole drilling.<br />
<br />
==On the fourth day – we move on to the Pi Fablet==<br />
A computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up – and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die – because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill. We will use a Raspberry Pi 4B quad core 1.5 ghz wuth 4GB RAM – a powerful base for a practical tablet. We are including a 7″ touch screen, a Camera v2 8 megapixel module capable of 4000 pixel horizontal resolution (4K) to work with, and a battery pack. These parts are all included in the STEAM Camp admission.<br />

==Narrative==<br />
===Day 1===<br />
<br />
On the first day – we provide an introduction to Open Source Ecology and collaborative design - for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to tranform the world’s economy from proprietary to collaboratve – with an accompanying cascade of positive change throughout the world. We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program. <br />
<br />
===Day 2===<br />
<br />
On the second day, we dive into the design aspect – with a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you'll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
<br />
The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them - or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer – by uploading new software, generating control code by hand, or using software such as Inkscape, KiCad, or FreeCAD to generate tool paths for your plotter or mill. Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines.

Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
===Day 3===<br />
On day 3, we move on to electronics - and make more fabrication tools while we are at it! We start with 3D design to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. Then we will use the CNC pen plotter that we built on Day 2 - to plot circuits on copper-clad board. We will then etch this circuit in a bath, and then CNC drill holes in it so we produce a circuit board. We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. We will then use this controller to switch large loads using a solid state relay to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device - demonstrating that we have the power to control kilowatts of electrical power automatically - using a microcontroller that we built ourselves - using a 3D printer and plotter that we made together from scratch. We will learn how to produce the circuit design in KiCad open source electronics software, and how to export files for circuit plotting and drilling from KiCad - so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
===Day 4===<br />
<br />
On the 4th day, we move on to the OSE Pi Fablet - a computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up - and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die - because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill.<br />
<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />
#Day 2: Printer Calibrations: Retraction calibration; filament feed calibration; perpendicular (skew) calibration; alignment of head parallel to bed and data point collection; how to modify menu to say My Name D3D Universal. <br />
#Day 3: KiCad lesson: KiCad Arduino stripboard - make a proper PCB - plot and drill.<br />
<br />
##KiCad workflow overview. Setup of project and KiCad interface. What version of KiCad to use for OSE and how to install it.<br />
##How to draw a schematic by starting with a voltage source, wire connections, an SSR, and a load such as a lightbulb.<br />
##How to insert more complex components - the 328p chip example<br />
##How to add through holes that will be turned into a drilling file<br />
##How to export a schematic<br />
##How to produce and export a layout<br />
##How to produce and export a CAM file (gerber). Is there any other alternatives here?<br />
##How to import the design into FreeCAD<br />
##How to generate toolpath for Marlin, either via FreeCAD or FlatCam.<br />

=Narrative=<br />
From website posting, we have a narrative:<br />
<br />
What are the critical tools that we need for effective collaborative design? These tools involve, first and foremost – Collaborative Literacy – a mindset and a practical process – that enables people to work together for the common good. Beyond these soft skills is a set of hard skills and interdisciplinary technical knowledge that enables one to come up with creative and effective design.<br />
<br />

==Day 4:== <br />
Raspberry Pi Tablet - Build of Fablet with camera + 3D Printed Case +[[Off The Shelf Bat Pack]]. Programming lesson for a Camera App. <br />
<br />
==Narrative==<br />
===Day 1===<br />
<br />
On the first day – we provide an introduction to Open Source Ecology and collaborative design - for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to tranform the world’s economy from proprietary to collaboratve – with an accompanying cascade of positive change throughout the world. We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program. <br />
<br />
===Day 2===<br />
<br />
On the second day, we dive into the design aspect – with a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you'll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
<br />
The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them - or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer – by uploading new software, generating control code by hand, or using software such as Inkscape, KiCad, or FreeCAD to generate tool paths for your plotter or mill. Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro - using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
===Day 3===<br />
On day 3, we move on to electronics - and make more fabrication tools while we are at it! We start with 3D design to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. Then we will use the CNC pen plotter that we built on Day 2 - to plot circuits on copper-clad board. We will then etch this circuit in a bath, and then CNC drill holes in it so we produce a circuit board. We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. We will then use this controller to switch large loads using a solid state relay to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device - demonstrating that we have the power to control kilowatts of electrical power automatically - using a microcontroller that we built ourselves - using a 3D printer and plotter that we made together from scratch. We will learn how to produce the circuit design in KiCad open source electronics software, and how to export files for circuit plotting and drilling from KiCad - so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
===Day 4===<br />
<br />
On the 4th day, we move on to the OSE Pi Fablet - a computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up - and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die - because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill.<br />
<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />
#Day 2: Printer Calibrations: Retraction calibration; filament feed calibration; perpendicular (skew) calibration; alignment of head parallel to bed and data point collection; how to modify menu to say My Name D3D Universal. <br />
#Day 3: KiCad lesson: KiCad Arduino stripboard - make a proper PCB - plot and drill.<br />
<br />
##KiCad workflow overview. Setup of project and KiCad interface. What version of KiCad to use for OSE and how to install it.<br />
##How to draw a schematic by starting with a voltage source, wire connections, an SSR, and a load such as a lightbulb.<br />
##How to insert more complex components - the 328p chip example<br />
##How to add through holes that will be turned into a drilling file<br />
##How to export a schematic<br />
##How to produce and export a layout<br />
##How to produce and export a CAM file (gerber). Is there any other alternatives here?<br />
##How to import the design into FreeCAD<br />
##How to generate toolpath for Marlin, either via FreeCAD or FlatCam.<br />

Plotting and drilling all afternoon. [https://photos.app.goo.gl/JzLqMwhbBLKJ2FAA7 Photos of plotting and drilling]. Fine point marker leaving large lines, will try ultra fine. Current Plan: Draw traces and pads with ultra fine tip, change offset and mill out holes.<br />
<br />
== '''Mon Mar 09:''' ==<br />
Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />
<br />
D3D-U Extruder jamb for second time today... think its the retract settings, but not really sure.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

<br />
Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />

G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />

G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

Started printing Angled Corners for D3D Pro. Learned a bit about removing scaffold and bed adhesion on D3D-U - Good adhesion printing directly onto buildtak on steel plate (preheat steel plate with heater, brim =5. Had to put plate in freezer to get release as large hammer and all the scrapers not effective. Spring steel plate adhesion great, so much so that plate warps = parts warped.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />
<br />
Started printing corner brackets.<br />
<br />
Reworked CAD for Fablet case. Hope to have something to post and print tomorrow.<br />
<br />
== '''February 7, 2020:''' ==<br />
Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

<br />
Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />

G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

D3D Pro bed modifications. Instructor planning call. Followup with venues... trying to secure a backup location.<br />
<br />
== '''February 18, 2020:''' ==<br />
Continued call and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
Finally heard back from Bellingham Makerspace at EOD, I think this is our location... waiting for 100% confirmation... <br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />
<br />
D3D-U Extruder jamb for second time today... think its the retract settings, but not really sure.<br />

Started printing Angled Corners for D3D Pro. Learned a bit about removing scaffold and bed adhesion on D3D-U - Good adhesion printing directly onto buildtak on steel plate (preheat steel plate with heater, brim =5. Had to put plate in freezer to get release as large hammer and all the scrapers not effective. Spring steel plate adhesion great, so much so that plate warps = parts warped.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />
<br />
Started printing corner brackets.<br />
<br />
Reworked CAD for Fablet case. Hope to have something to post and print tomorrow.<br />
<br />
== '''February 7, 2020:''' ==<br />
Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Drafted a [https://wiki.opensourceecology.org/wiki/File:TabletScreenBezel.fcstd bezel for testing screen fit]. Updated size and fit for [https://wiki.opensourceecology.org/wiki/File:PiboardandMount.fcstd Piholder piece].

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

<br />
Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />

Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />

<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

From website posting, we have a narrative:<br />
<br />
What are the critical tools that we need for effective collaborative design? These tools involve, first and foremost – Collaborative Literacy – a mindset and a practical process – that enables people to work together for the common good. Beyond these soft skills is a set of hard skills and interdisciplinary technical knowledge that enables one to come up with creative and effective design.<br />
<br />
'''On the first day:'''<br />
#we provide an introduction to Open Source Ecology and collaborative design – for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to transform the world’s economy from proprietary to collaborative – with an accompanying cascade of positive change throughout the world. 1 hour.<br />
#We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program.<br />
<br />
'''On the second day – we dive into the design aspect:'''<br />
#a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you’ll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
#The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them – or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer. <br />
#Generating control code by hand with a super-basic lesson on g-code generation. This is useful whenever you want custom operation, whenever software for the specific task you need is not available, or whenever you are doing something so simple that it's easier to generate code by hand.<br />
#Generate control code using software such as Inkscape, KiCad, or FreeCAD. These can be used for drawings or to generate tool paths for your plotter or CNC hole drill. <br />
#Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
#Simple exercise - draw something simple in Inkscape, and convert it to a plot while doing Marlin-based auto leveling.This kind of workflow is important because you can use it for many different purposes: a vinyl cutter, a CNC torch table with automatic leveling + operator adjustment.<br />
#Flow of Day 2: start with designing something basic for a 5 minute print job - of a bit holder. Move into Inkscape and plotting, with insights of how to use the plotter for drawing, printing cutting patterns onto a metal substrate, and circuit plotting. The idea here is to master digital control of 2-dimensional motion, which serves as a basic for multiaxis machining - such as with a screw machine<br />
#Last task: set up a print at the end of the day for the CNC Drill Attachment.<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro – using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
'''On the third day – we move on to electronics'''<br />
#Aand make more fabrication tools while we are at it! We start with 3D CAD to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. <br />
#Then we will use the CNC pen plotter that we built on Day 2 – to plot circuits on copper-clad board. We will then etch this circuit in a bath...<br />
#and then CNC drill holes in it so we produce a circuit board. <br />
#We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. <br />
#We will then use this controller to switch large loads using a solid state relay...<br />
#...to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device – demonstrating that we have the power to control kilowatts of electrical power automatically – using a microcontroller that we built ourselves – using a 3D printer and plotter that we made together from scratch. <br />
#We will learn how to produce the circuit design in KiCad open source electronics software, <br />
#and how to export files for circuit plotting and drilling from KiCad – so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
On the fourth day – we move on to the Pi Fablet – a computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up – and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die – because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill. We will use a Raspberry Pi 4B quad core 1.5 ghz wuth 4GB RAM – a powerful base for a practical tablet. We are including a 7″ touch screen, a Camera v2 8 megapixel module capable of 4000 pixel horizontal resolution (4K) to work with, and a battery pack. These parts are all included in the STEAM Camp admission.<br />
<br />
<br />

===Day 1===<br />
<br />
On the first day – we provide an introduction to Open Source Ecology and collaborative design - for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to tranform the world’s economy from proprietary to collaboratve – with an accompanying cascade of positive change throughout the world. We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch.

<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />
#Day 2: Printer Calibrations: Retraction calibration; filament feed calibration; perpendicular (skew) calibration; alignment of head parallel to bed and data point collection; how to modify menu to say My Name D3D Universal. <br />
#Day 3: KiCad lesson: KiCad Arduino stripboard - make a proper PCB - plot and drill.<br />
<br />
##KiCad workflow overview. Setup of project and KiCad interface. What version of KiCad to use for OSE and how to install it.<br />
##How to draw a schematic by starting with a voltage source, wire connections, an SSR, and a load such as a lightbulb.<br />
##How to insert more complex components - the 328p chip example<br />
##How to add through holes that will be turned into a drilling file<br />
##How to export a schematic<br />
##How to produce and export a layout<br />
##How to produce and export a CAM file (gerber). Is there any other alternatives here?<br />
##How to import the design into FreeCAD<br />
##How to generate toolpath for Marlin, either via FreeCAD or FlatCam.<br />

==Day 4:== <br />
Raspberry Pi Tablet - Build of Fablet with camera + 3D Printed Case +[[Off The Shelf Bat Pack]]. Programming lesson for a Camera App. <br />
<br />
==Narrative==<br />
===Day 1===<br />
<br />
On the first day – we provide an introduction to Open Source Ecology and collaborative design - for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to tranform the world’s economy from proprietary to collaboratve – with an accompanying cascade of positive change throughout the world. We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program. <br />
<br />
===Day 2===<br />
<br />
On the second day, we dive into the design aspect – with a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you'll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
<br />
The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them - or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer – by uploading new software, generating control code by hand, or using software such as Inkscape, KiCad, or FreeCAD to generate tool paths for your plotter or mill. Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro - using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
===Day 3===<br />
On day 3, we move on to electronics - and make more fabrication tools while we are at it! We start with 3D design to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. Then we will use the CNC pen plotter that we built on Day 2 - to plot circuits on copper-clad board. We will then etch this circuit in a bath, and then CNC drill holes in it so we produce a circuit board. We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. We will then use this controller to switch large loads using a solid state relay to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device - demonstrating that we have the power to control kilowatts of electrical power automatically - using a microcontroller that we built ourselves - using a 3D printer and plotter that we made together from scratch. We will learn how to produce the circuit design in KiCad open source electronics software, and how to export files for circuit plotting and drilling from KiCad - so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
===Day 4===<br />
<br />
On the 4th day, we move on to the OSE Pi Fablet - a computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up - and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die - because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill.<br />
<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />
#Day 2: Printer Calibrations: Retraction calibration; filament feed calibration; perpendicular (skew) calibration; alignment of head parallel to bed and data point collection; how to modify menu to say My Name D3D Universal. <br />

Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill [[File:RouterToolhead.FCStd]]. Export gcode from Inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M0; Pause after 0,0 for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G92 Z0 ;z- set 4.00 to now be 0 to keep drill out of work area.<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M0 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M0; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
G92 Z0 ;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the xy zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />
</pre><br />
Save the file then load in CURA - Activate control window - M0 Pauses allow stops/resumes and injection of manual gcode via cmd line via CURA. (also get nice progress bar to help pass the waiting)<br />

Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

Started printing Angled Corners for D3D Pro. Learned a bit about removing scaffold and bed adhesion on D3D-U - Good adhesion printing directly onto buildtak on steel plate (preheat steel plate with heater, brim =5. Had to put plate in freezer to get release as large hammer and all the scrapers not effective. Spring steel plate adhesion great, so much so that plate warps = parts warped.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />
<br />
Started printing corner brackets.<br />
<br />
Reworked CAD for Fablet case. Hope to have something to post and print tomorrow.<br />
<br />
== '''February 7, 2020:''' ==<br />
Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

<br />
Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />
<br />
== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />
[[File:JeremyCarriageBracket.png|200px]]<br />
<br />
Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

<br />
Finally heard back from Bellingham Makerspace at EOD, I think this is our location... waiting for 100% confirmation... <br />
<br />
== '''February 17, 2020:''' ==<br />
Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />
[[File:PiFullCaseMockUp.png|100px]]<br />
<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />

== '''February 1, 2020:''' ==<br />
Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />
[[File:PiBootedWithOnly1Power.png|200px]] [[File:PiBootedWithOnly1PowerCloseUp.png|200px]]<br />
<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />

Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />

=Curriculum=<br />
<br />
From website posting, we have a narrative:<br />
<br />
What are the critical tools that we need for effective collaborative design? These tools involve, first and foremost – Collaborative Literacy – a mindset and a practical process – that enables people to work together for the common good. Beyond these soft skills is a set of hard skills and interdisciplinary technical knowledge that enables one to come up with creative and effective design.<br />
<br />
'''On the first day:'''<br />
#we provide an introduction to Open Source Ecology and collaborative design – for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to transform the world’s economy from proprietary to collaborative – with an accompanying cascade of positive change throughout the world. 1 hour.<br />
#We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program.<br />
<br />
'''On the second day – we dive into the design aspect:'''<br />
#a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you’ll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
#The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them – or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer. <br />
#Generating control code by hand with a super-basic lesson on g-code generation. This is useful whenever you want custom operation, whenever software for the specific task you need is not available, or whenever you are doing something so simple that it's easier to generate code by hand.<br />
#Generate control code using software such as Inkscape, KiCad, or FreeCAD. These can be used for drawings or to generate tool paths for your plotter or CNC hole drill. <br />
#Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
#Simple exercise - draw something simple in Inkscape, and convert it to a plot while doing Marlin-based auto leveling.This kind of workflow is important because you can use it for many different purposes: a vinyl cutter, a CNC torch table with automatic leveling + operator adjustment.<br />
#Flow of Day 2: start with designing something basic for a 5 minute print job - of a bit holder. Move into Inkscape and plotting, with insights of how to use the plotter for drawing, printing cutting patterns onto a metal substrate, and circuit plotting. The idea here is to master digital control of 2-dimensional motion, which serves as a basic for multiaxis machining - such as with a screw machine<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro – using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
On the third day – we move on to electronics – and make more fabrication tools while we are at it! We start with 3D design to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. Then we will use the CNC pen plotter that we built on Day 2 – to plot circuits on copper-clad board. We will then etch this circuit in a bath, and then CNC drill holes in it so we produce a circuit board. We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. We will then use this controller to switch large loads using a solid state relay to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device – demonstrating that we have the power to control kilowatts of electrical power automatically – using a microcontroller that we built ourselves – using a 3D printer and plotter that we made together from scratch. We will learn how to produce the circuit design in KiCad open source electronics software, and how to export files for circuit plotting and drilling from KiCad – so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
<br />
<br />
On the fourth day – we move on to the Pi Fablet – a computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up – and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die – because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill. We will use a Raspberry Pi 4B quad core 1.5 ghz wuth 4GB RAM – a powerful base for a practical tablet. We are including a 7″ touch screen, a Camera v2 8 megapixel module capable of 4000 pixel horizontal resolution (4K) to work with, and a battery pack. These parts are all included in the STEAM Camp admission.<br />
<br />
<br />

==Day 4:== <br />
Raspberry Pi Tablet - Build of Fablet with camera + 3D Printed Case +[[Off The Shelf Bat Pack]]. Programming lesson for a Camera App. <br />
<br />
==Narrative==<br />
===Day 1===<br />
<br />
On the first day – we provide an introduction to Open Source Ecology and collaborative design - for a transparent and inclusive economy of abundance. We discuss the potential of open source, collaborative design to tranform the world’s economy from proprietary to collaboratve – with an accompanying cascade of positive change throughout the world. We dive right in from the theory to creating industrial productivity on a small scale: building our own 3D printers from scratch. Each person builds a rapid prototyping 3D printer from scratch, and runs a first print on the same day. The 3D Printer is called D3D Universal – a 3-axis machine with quick-connect tool heads. This is the machine that we will use to build 2 more tool heads throughout the rest of the program. <br />
<br />
===Day 2===<br />
<br />
On the second day, we dive into the design aspect – with a crash course on FreeCAD – an open source computer-aided design (CAD) tool. In one hour, we will teach you how to go from an idea in your head – to a basic design workflow – and end up with an object that you can print readily on your own 3D printer that you just built. Throughout the program, you'll be able to practice your CAD design skills with other simple designs in FreeCAD as you build your skills. All the things you design will be practical tools tools or parts that you then print and use – and upload online so anyone can benefit from them or improve them.<br />
<br />
The practical designs of the second day is pen plotter. You can either print out existing designs that we have provided – or you can modify them - or you can create your own. The pen holder turns your D3D Universal into a CNC pen plotter for drawing pictures or circuits. You will learn how to control these machines with the same Universal Controller as the 3D printer – by uploading new software, generating control code by hand, or using software such as Inkscape, KiCad, or FreeCAD to generate tool paths for your plotter or mill. Because D3D Universal has a height sensor, you will learn how to level the workpiece automatically for plotting.<br />
<br />
<br />
The intent of these exercises is to learn how these machines work, to the point that you can design and build a modified, larger, or more robust version that can be used in production. While the tools built are entry level and focused on education, they have a clear path of extensibility and scalability that allows them to become workhorse machines. With the tools and skills gained, and a support community to help – we encourage people to start open source microfactories that contribute to a circular economy based on global, collaborative design. For example, you can print our professional grade printer – D3D Pro - using the D3D Universal – so that you can bootstrap readily to real production. Or, you can even print parts for a CNC Torch table for cutting metal parts. In fact, our build techniques can be applied readily to make heavy CNC machines for milling steel.<br />
<br />
===Day 3===<br />
On day 3, we move on to electronics - and make more fabrication tools while we are at it! We start with 3D design to design or modify a CNC drill attachment, which we will then print and add to our toolchest of open source CNC tools. Then we will use the CNC pen plotter that we built on Day 2 - to plot circuits on copper-clad board. We will then etch this circuit in a bath, and then CNC drill holes in it so we produce a circuit board. We then add components to this board and make a functional, minimalist Arduino Uno microcontroller. We will then use this controller to switch large loads using a solid state relay to deomonstrate that this self-made microcontroller actually works and does what you program it to do. We will program the arduino using simple programming code to switch on a wall light or fan or any other electrical device - demonstrating that we have the power to control kilowatts of electrical power automatically - using a microcontroller that we built ourselves - using a 3D printer and plotter that we made together from scratch. We will learn how to produce the circuit design in KiCad open source electronics software, and how to export files for circuit plotting and drilling from KiCad - so we can plot and drill anything we want on the D3D Universal machine.<br />
<br />
===Day 4===<br />
<br />
On the 4th day, we move on to the OSE Pi Fablet - a computer tablet based on the Raspberry Pi 4B+ microcomputer. We will design and print the enclosure, add a camera lens and touch-screen display, wire it all up - and make a functional, practical touch-screen tablet intended for every-day use. We will even learn to program a simple camera app by the end of the 4th day! The intent is to have this become part of a continuing and collaborative effort to make a practical product that can be produced anywhere in the world. The advantage of open source design is that the Fablet will never die - because you can modify it for ever, replace parts, and create new functionality using its powerful 64-bit quad core processor running at 1.5GHz. This is an example of eco-friendly design, where lifetime design can keeps this product from ending up in a landfill.<br />
<br />
==Expected Outcomes==<br />
#Day 1: '''Good overview of OSE's vision''' (summarized in [[Vision]], collaborative design process, roadmap for enterprise scaling of 2020 from STEAM -> Summer X -> The World's First Collaborative Incentive Challenge. Not trying to be haughty here - we emphasize how the Challenge is different from any other to date. That is NOT an overstatement, and we should make that clear: the distinction between a challenge where people compete, vs collaborate. From FIRST to HeroX - everything that at least I know of is competitive (not collaborative), undocumented (but could be collaborative, such as inside a corporation), or both, and I would love to hear of examples to the contrary. '''Successful print on the first try'''. We have a well-defined checklist and quality control procedure (need to improve documentation of it) - and we can do a final dry quality control for the electronics prior to making all the connections prior to final install and wiring of control panel. We can take all the components, and verify in a 5-30 minute procedure (including part replacements if needed) that all components are working. All electronics are tested prior to shipping kits, and we can verify that nothing was damaged in transport using a [[Final Five Minute Control Panel Test]]. Then when we wire everything up, correcting direction of axis motion only takes a few minutes. Once motion on 4 axes is verified (includes check of extruder direction via control panel) - the first print is guaranteed to succeed. Period. This is a procedure that all instructors need to master to provide a seamless experience, and to teach the process to participants.<br />
#Day 2: Printer Calibrations: Retraction calibration; filament feed calibration; perpendicular (skew) calibration; alignment of head parallel to bed and data point collection; how to modify menu to say My Name D3D Universal. <br />
#Day 3: KiCad lesson: KiCad Arduino stripboard - make a proper PCB - plot and drill.<br />

Emails and planning for upcoming events. Review Plotter and mill Curriculum - Collated links and learnings at [[STEAM_Camp_9_Day_Curriculum]]. Modified [[File:RouterToolhead.FCStd]] with additional pen holder, hoping to plot and then drill without tool change (was suggested by Belgium group I think?). Working price quote for shredder teeth.<br />
<br />
Plot and Drill Plan:<br />
Use combined plotter/mill. Export gcode from inkscape and open for manually editing.<br />
Edit:<br />
<pre><br />
;load gcode file into CURA - for access to gcode command-line during pauses<br />
M226; Pause after first home for inserting pen<br />
;move z zero up to avoid hitting mill bit on work surface - <br />
;G00 F300.0 Z4.000; z down<br />
;Insert pen then zero z here<br />
G90 z- set absolute positioning<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
G00 F300.0 Z0.000; pen down !!Zwork<br />
G00 F300.0 Z5.000; pen up !!Zup<br />
M226 ;pause - verify correct marks at home zero - will use these to adjust offset of mill bit later.<br />
Do plotting gcode<br />
;At end of file - back to x0,y0<br />
G00 F2400.0 Y0.000; !!Ybottom<br />
G00 F2400.0 X0.000; !!Xleft<br />
G00 F300.0 Z20.000; pen up !!<br />
M226; Pause - remove/lift pen and add or adjust height of mill be sure NOT TO BUMP the bed.<br />
;line up drill manually<br />
;manually drill the alignment hole very slowly<br />
;set z zero once hole is sufficiently deep<br />
;commence drilling - insert hole punching gcode following<br />
;suggest drilling code have a higher z clearance - more vertical movement between x y moves<br />
;the goal is to use one gcode file to plot all the traces, then adjust the zero so that the drill can hit the correct positions. Not removing the PCB during this operation should assure everything is aligned correctly.<br />
;TODO-determine the X Y offset between pen and drill on a test plot of wood/cardboard, hard code into gcode file with pauses for verify and power up drill.<br />

Finally heard back from Bellingham Makerspace at EOD, I think this is our location... waiting for 100% confirmation... <br />
<br />
== '''February 17, 2020:''' ==<br />
Called and emailed for a Bellingham/Seattle Venue - All day.<br />
<br />
== '''February 16, 2020:''' ==<br />
Compiled list of local career councilor email addresses. Spent time looking for a venue for the upcoming class. Contacted several local teachers I know re:workshop. Prepared emails scripts for sending once venue secured. Joined several Facebook groups where I can publicize the workshop. Started process of renewing my WWU system credentials to post events in WWU bulletin board system. Posted event in [[https://www.whatcomtalk.com/ WhatcomTalk page]]. Looked up several "influencers" on Youtube, planning to ask them to plug us in the next week or two (we could even send them a kit and ask for a review!). Emailed two addresses associated with Adam Savage (wouldn't it be great if he started plugging for OSE). <br />
<br />
Consulted friend who manages online marketing, for some very large companies, in regards to best strategies for drumming up workshop participants. <br />
<br />
* If we have paid budget use it on FB or Twitter. If the event is in Bellingham, do a geo targeting around the area as I would assume most people that can fly would attend the other in person events as they seem to be larger. You should also look into LinkedIn. <br />
*For free stuff, look to join groups and post mercilessly. Groups would be on Facebook and LinkedIn. <br />
*In a general sense, see if you can find "influencers" in this area and ask if they would be willing to help promote. So look for people on YouTube, Twitter, Facebook, LinkedIn, etc who have larger or engaged audiences who focus on this kind of stuff and send them a note. It never hurts to ask!<br />
*Lastly, going to high schools and colleges is not a bad idea at all. Specifically schools with technical clubs or programs. "<br />
<br />
He offered to help out with our marketing in his spare time if he can have a printer... I offered to order everything at cost and help build. I think he'll help us out once his super busy next couple months blow by. Finally, I asked him to come to a workshop as a documenter, to get a feel for it and help with capturing what we do for instructionals and future marketing.<br />

D3D Pro Parts Ordering and Research. Planning to put together in the next few weeks. Ordering components from aliexpress, planning to pull parts from universal if they don't arrive in time. Walked thru wiring, current instructions, crossreference for D3D-U to D3D Pro to D3D 19.06 and hopefully have a complete list of what we need to order, print, and what we can steal from the D3D-U that we have on site. <br />

Work on Pi tablet design and assembly concept mockup. See Parts Library [https://wiki.opensourceecology.org/wiki/Part_Library_for_the_Raspberry_Pi_Tablet] or design Google Doc. These need to be redrawn to fit/scale exactly with Pi and screen. This served as a quick way to visualize how to print this in layers, hopefully will help others as well. The bezel needs to have screen mounting loops inset. Hoping to hold the entire case together with 6 or 8 screws externally. <br />
<br />

<br />
Camera??? Also, where/how do we put the camera on? I thought it would nice to have it on a pivot/hinge at the "top", so it can be used for conferencing and as a hand held camera easily? Pivot up over the "top" to point at the user, pivot back and tuck into back side of screen for hand held camera mode. Need to come up with a printable hinge that a ribbon cable can run through.<br />

Power and USB alternate input to display on Pi Fablet attempted and verified. New Minor Problem: When Pi is shutdown from OS, Pin 4 still have 5v, so screen stays on until USB is powered off or disconnected.

Uploaded a CAD mock-up for [https://wiki.opensourceecology.org/wiki/File:FabTabLayout.fcstd PiCase] with notches/inset rear slots so that the important connectors can be accessed on the Pi. Mock-up includes an area for the forth coming OSE battery pack. Notes/thoughts in [https://docs.google.com/presentation/d/1su4L4bdFBVHVab2EqahNznJyknjIvKCZ4lwFrV8P7lg/edit#slide=id.g76c4c99b0e_6_3 dev working document].<br />

Worked on Pi Power issues. Discovered that screen (powered from Pi via USB) and Pi (powered from wall) would not load or power up. If they are each powered from a wall adapter, they boot normally. Tried using power from the 5v (pin 4)on the GPIO rail to run screen. Made USB cable (only power wires) to 2 pin connector (stole connector off old GPU fan). Routed this to pins 4 and 6. Both Pi and screen boot up right away. This seems the only way to power the screen from the Pi and reduce the incoming power cables from wall to case to 1. <br />
<br />
NOTE: The USB cannot power the screen during BOOT, but was able to power the screen if the USB to screen was switched to Pi after BOOT. <br />
<br />
Could also use a battery pack like [[https://www.amazon.com/26800mAh-Portable-Charger-Battery-Nintendo/dp/B073FJ9X2J Battery Bank]] and leave the charging port exposed and then use normal USB wires inside the case to power screen and Pi. Might be possible to modify Pi boot up to keep the USB off until OS is loaded, would not rely on a hardware hack to complete. <br />
<br />

<br />
'''TL;DR:''' Found workaround for power issues, will reduce case size as well.<br />
<br />
*TODO: Explore sending power directly from GPIO pin 4 to the 5v solder pad/test point on back of screen. This could eliminate all need for a USB power Line.<br />
*TODO: Explore/Test USB solder pad to USB connector, may provide touch screen interface and power without using any USB ports on PI, making it easy to leave them at the edge of case and accessible. (this would require soldering these lines directly to the underside of the PiBoard on the correct pins, and may be a more involved solution than we are looking for, but still worth investigating)<br />
<br />
Installed raspbian OS. Had some issues getting correct resolution on display. Manually set resolution in /boot/config.txt to 1088 x 600 (its 600x something odd... don't remember exactly). Very odd, but the stated native resolution left back side bars.<br />
<br />
Printed of "L" carriage bracket for z-axis on D3D-U. The initial bracket not square. Planning to try to straighten, but wanted spare on hand.<br />
<br />

Ran multi-meter on solder pads(factory test locations?) on back of Pi display we have been working on. Confirmed that labels on board correspond to the correct pins on the USB circuit. <br />

'''D3D Issue-O-Day:'''<br />
<br />
Started printing plotter attachment and y-axis movement issues. Spend to long on troubleshoot. Ended up tweaking alignment of rails, and tracking down idler bearing not spinning freely. Also learned that the nozzle heat break fan is really good for ruining adhesion on the side of the bed its aimed at. Thinking future versions should move the air upwards, or possibly turn the fan off for the first few layers. Can we find a passive cooling solution?<br />
<br />
Experiencing slight nozzle drag on nozzle moves. Is this an axis alignment issue, carriage free movement, or steps/mm? Read up on OS install to Pi, played with Pi parts like giant Legos... how best to fit together to achieve thin form factor.<br />
