<br />
- installed OSEdev-WB (incl. OSEdev Backend on Postgres DB) with help from Lex<br />
<br />
<br />
- tested D3D-WB, checking for import-problem, mailed with Stephen<br />
<br />
<br />
<br />
<br />
<br />

<br />
<br />
- tested Web-GL export from FreeCad. There is a rudimentary export-funktion available within Freecad, but it failed with more complex assembled objects. With simple objects it worked, but the result seems to have issues with the line width. Also colours get lost. I was however able to get into the resulting Web-GL/xml-code and setting manually an object-colour and also a bigger stroke-width. So these effects doesnt seem to be a bug, its just that the export script is still quite rudimentary and simple. But maybe a good point to start from. I have listed some basic links to Web-GL onto my discussion page at http://opensourceecology.org/wiki/Talk:Oliver_Log#Wed.2C_Oct.2C25.2C2017<br />
<br />
<br />
- started exploring the WB stuff that Stephen has collected so far. It looks promising.<br />
<br />
<br />

<br />
- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s with MPPT-20A Charge-Controler and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />
<br />
<br />
Solarbox-Specs:<br />
<br />
* 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)<br />
<br />
* suited for about 400Wp Solarpanel-input (or more with minor mods)<br />
<br />
* Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU<br />
<br />
* Solar-Charge-Controler: MPPT, up to 20A<br />
<br />
* dimensions about 44 x 32 x 20 cm<br />
<br />
* Inverter: Victron Phoenix 12/350<br />

- i had some Slack-discussions and testing on the Duniter/Gt1 system with Lex and Josh<br />
<br />
<br />
<br />
<br />

<br />
- attended TorchTable Workshop online for kicad walkthrough TorchHeightCTRL pbc and Shanes kicad tutorial<br />
<br />
<br />
<br />
<br />
= '''Tue Oct 10, 2017''' =<br />
<br />
- Made Video that shows how to deploy the TorchHeightCTRL_V.02 sources from Github [https://github.com/case06/TorchHeightCTRL] on Kicad. <br />
<br />
See on youtube https://www.youtube.com/watch?v=v-nhG5vuZW0<br />
<br />
- installed and tested slack<br />
<br />
<br />
<br />
<br />
<br />
= '''Tue Oct 03, 2017''' =<br />
<br />
<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />
<br />

<br />
- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- today i received an order from a special material filament named "Iglidur I150 Tribo-Filament" from Igus [http://www.igus.de/product/12404]. This is specially suited for 3dprinting sliding parts and is about 50 times less abrasive than ABS.<br />
<br />
I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- Some checkpoints when trying to make the new pcb running:<br />
<br />
<br />
* Start with a testrig (a single D3D-axis), dont mount it immediately to the torchtable without prior testing<br />
<br />
* Check Step-Width, e.g. if the pulley has a different tooth-number and diameter stepwidth can be different, too<br />
<br />
* Check serial data-output for reasonable values before switching on the steppers (by the powersupply; the nano meanwhile can run "dry" by getting power from the USB-datacable). Do this with holding a metal plate in 0mm up to 30mm distance.<br />
<br />
* Dont start the steppers, without having the sensorhead installed and holding a metal-plate in front of it. Other wise it would produce zero-values and when trying to balance the algorithm would add more and more steps for compensation and the stepper would go through the wall.<br />
<br />
* make sure you have have connected the metal plate and as well the testrig-structure to the SHIELD-ground<br />
<br />
* Startposition is with 0mm distance. From this it will take a sample and then goes to 30mm and take another sample for calibration. Then it will go in a loop and trying to balance the distance around 15mm. I am going to upload a new firmware-version where endstop and jogwheel button will be integrated. Then the 0mm-position will be found automatically by homing. The 15mm will act as a default-value, but if you then push the button you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />
<br />
* make sure the power-connector is on 5V and not on 12V (!!!)<br />

THCctrl, TB6600: In some wiring diagrams you find a common +5V line on EN,DIR,PUL (=STEP) in others they have a common ground. It seems that both is possible, see: [https://github.com/Arduinolibrary/TB6600_Stepper_Motor_Driver/raw/master/TB6600%20User%20Guide%20V1.2.pdf], [https://www.dfrobot.com/wiki/index.php/TB6600_Stepper_Motor_Driver_SKU:_DRI0043] and the links in [http://opensourceecology.org/wiki/Chas_log#May_30_2017 Chas' log].<br />
<br />
<br />
<br />
In RAMPS-like configurations it is often seen as common-ground connection [http://www.zyltech.com/tb6600.html] and sometimes with EN left unconnected. I assume its ok to connect EN, because otherwise the state of the stepper cannot be controlled externally. EN means that the stepper is active and draws current even if it doesnt move (and therefore getting warm). But there can be situations where its safe to inactivate that, e.g. wehn a 3Dprinter disables the steppers as soon as the print is finished. So this should be manageable by the controler.<br />

Idea to make a D3D-workshop completely relaxed: Just preproduce a number of printers and calibrate them perfectly. If someone doesnt get its own one ready during the course he can take a readymate one. So the promise "you get out here with a running printer" can be easily fullfilled and the workshop is completely free from any stress and totally relaxed (= best learning conditions)<br />
<br />
An interesting extension to this idea could be to let any class produce the printers for the next class (and take home a printer from the last class). So any printer creator becomes a kind of responsible godfather to someone elses printer (social relation ;)) Dont know whether the attendees really want that (but one could ask them; the surplus bonus is a nicely calibrated and perfectly running printer).<br />

Lesson learned: I tried in Kicad unsuccessfull different ways to import the 3d .wrl-files automatically, eg. by environment path-variable $KISYS3DMOD, but it is however possible to assign manually a 3d-form towards a footprint by editing its parameters (right mouseclick over footprint, then choose the footprint and in its 3d-settings the "add form" button) and let it point towards your local library-path .wrl-file. There you can also correct wrong orientations of the object, e.g. in a diode.<br />

<br />
This is a known problem and theoretically there exists a way to fix it, see [https://rheingoldheavy.com/new-stable-kicad-10-steps-to-import-an-old-kicad-project/ https://rheingoldheavy.com/new-stable-kicad-10-steps-to-import-an-old-kicad-project/], but its way to complicated to go through this procedure. Meaning, since Pauls circuit is not too complicated its probably far less work to simply rebuild it from scratch.<br />

Suggestions for the long axis:<br />
<br />
<br />
- supportet Rails [https://www.dold-mechatronik.de/navi.php?a=45377&lang=eng#&gid=1&pid=1] would be nice for better stiffness and rigidity (see [https://www.youtube.com/watch?v=TSTThLM8s8o] at minute 0:30) . Makes a price difference of about 20,- EUR or less per m .<br />
<br />
* Instead of one 1"-shaft we could use two 1/2"-shafts to resemble the recent unversal axis design as is.<br />
<br />
* Or instead we can use just one 1"-shaft and place the stepper onto the carriage (like shapeoko) <br />
==> simplyfied end-pieces (they are only needed to fix the belt).<br />
<br />
<br />
<br />
<br />
- Universal Controler: Powerlolu as stepperdriver for heavier loads ?<br />

This is a known problem and theoretically there exists a way to fix it, see [https://rheingoldheavy.com/new-stable-kicad-10-steps-to-import-an-old-kicad-project/ https://rheingoldheavy.com/new-stable-kicad-10-steps-to-import-an-old-kicad-project/], but its way to complicated to go through this procedure. Meaning, since Pauls circuit is not too complicated its probably far less work to simply rebuild it from scratch.<br />

<br />
what about mechanical probing ? https://www.indiegogo.com/projects/bltouch-auto-bed-leveling-sensor-for-3d-printers#/<br />
Answer: probably not well suited because of the heat.<br />

Preparation for torchtable-workgroup meeting on 23.05.:<br />
<br />
Suggestions for the long axis:<br />
<br />
<br />
- supportet Rails [https://www.dold-mechatronik.de/navi.php?a=45377&lang=eng#&gid=1&pid=1] would be nice for better stiffness and rigidity (see [https://www.youtube.com/watch?v=TSTThLM8s8o] at minute 0:30) . Makes a price difference of about 20,- EUR or less per m .<br />
<br />
* Instead of one 1"-shaft we could use two 1/2"-shafts to resemble the recent unversal axis design as is.<br />
<br />
* Or instead we can use just one 1"-shaft and place the stepper onto the carriage (like shapeoko) <br />
==> simplyfied end-pieces (they are only needed to fix the belt).<br />
<br />
<br />
<br />
<br />
- Universal Controler: Powerlolu as stepperdriver for heavier loads ?<br />
<br />
* Was already discussed on OSE in 2013, see [http://opensourceecology.org/wiki/Powerlolu]<br />

- tested Web-GL export from FreeCad. There is a rudimentary export-funktion available within Freecad, but it failed with more complex assembled objects. With simple objects it worked, but the result seems to have issues with the line width. Also colours get lost. I was however able to get into the resulting Web-GL/xml-code and setting manually an object-colour and also a bigger stroke-width. So these effects doesnt seem to be a bug, its just that the export script is still quite rudimentary and simple. But maybe a good point to start from. I have listed some basic links to Web-GL onto my discussion page at http://opensourceecology.org/wiki/Talk:Oliver_Log#Wed.2C_Oct.2C25.2C2017<br />

- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s with MPPT-20A Charge-Controler and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />
<br />
<br />
Solarbox-Specs:<br />
<br />
* 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)<br />
<br />
* suited for about 400Wp Solarpanel-input (or more with minor mods)<br />
<br />
* Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU<br />
<br />
* Solar-Charge-Controler: MPPT, up to 20A<br />
<br />
* dimensions about 44 x 32 x 20 cm<br />
<br />
* Inverter: Victron Phoenix 12/350<br />

<br />
<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />

- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- Some checkpoints when trying to make the new pcb running:<br />
<br />
<br />
* Start with a testrig (a single D3D-axis), dont mount it immediately to the torchtable without prior testing<br />
<br />
* Check Step-Width, e.g. if the pulley has a different tooth-number and diameter stepwidth can be different, too<br />
<br />
* Check serial data-output for reasonable values before switching on the steppers (by the powersupply; the nano meanwhile can run "dry" by getting power from the USB-datacable). Do this with holding a metal plate in 0mm up to 30mm distance.<br />
<br />
* Dont start the steppers, without having the sensorhead installed and holding a metal-plate in front of it. Other wise it would produce zero-values and when trying to balance the algorithm would add more and more steps for compensation and the stepper would go through the wall.<br />
<br />
* make sure you have have connected the metal plate and as well the testrig-structure to the SHIELD-ground<br />
<br />
* Startposition is with 0mm distance. From this it will take a sample and then goes to 30mm and take another sample for calibration. Then it will go in a loop and trying to balance the distance around 15mm. I am going to upload a new firmware-version where endstop and jogwheel button will be integrated. Then the 0mm-position will be found automatically by homing. The 15mm will act as a default-value, but if you then push the button you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />
<br />
* make sure the power-connector is on 5V and not on 12V (!!!)<br />

THCctrl, TB6600: In some wiring diagrams you find a common +5V line on EN,DIR,PUL (=STEP) in others they have a common ground. It seems that both is possible, see: [https://github.com/Arduinolibrary/TB6600_Stepper_Motor_Driver/raw/master/TB6600%20User%20Guide%20V1.2.pdf], [https://www.dfrobot.com/wiki/index.php/TB6600_Stepper_Motor_Driver_SKU:_DRI0043] and the links in [http://opensourceecology.org/wiki/Chas_log#May_30_2017 Chas' log].<br />

<br />
<br />
In RAMPS-like configurations it is often seen as common-ground connection [http://www.zyltech.com/tb6600.html] and sometimes with EN left unconnected. I assume its ok to connect EN, because otherwise the state of the stepper cannot be controlled externally. EN means that the stepper is active and draws current even if it doesnt move (and therefore getting warm). But there can be situations where its safe to inactivate that, e.g. wehn a 3Dprinter disables the steppers as soon as the print is finished. So this should be manageable by the controler.<br />

Idea to make a D3D-workshop completely relaxed: Just preproduce a number of printers and calibrate them perfectly. If someone doesnt get its own one ready during the course he can take a readymate one. So the promise "you get out here with a running printer" can be easily fullfilled and the workshop is completely free from any stress and totally relaxed (= best learning conditions)<br />
<br />
An interesting extension to this idea could be to let any class produce the printers for the next class (and take home a printer from the last class). So any printer creator becomes a kind of responsible godfather to someone elses printer (social relation ;)) Dont know whether the attendees really want that (but one could ask them; the surplus bonus is a nicely calibrated and perfectly running printer).<br />

Trying to re-use Pauls KiCad-Files run into the problem of beeing an older Version, what means all links are broken, see all the question marks in<br />
<br />
<gallery widths="360" perrow="1" caption="Reimport-problem on older Kicad files"><br />
Os_log_23.05.2017_reimport_problem.png| All default parts are in the newer Kicad version replaced by smaller ones, so the links are broken<br />
</gallery><br />
<br />
This is a known problem and theoretically there exists a way to fix it, see [https://rheingoldheavy.com/new-stable-kicad-10-steps-to-import-an-old-kicad-project/ https://rheingoldheavy.com/new-stable-kicad-10-steps-to-import-an-old-kicad-project/], but its way to complicated to go through this procedure. Meaning, since Pauls circuit is not too complicated its probably far less work to simply rebuild it from scratch.<br />

what about mechanical probing ? https://www.indiegogo.com/projects/bltouch-auto-bed-leveling-sensor-for-3d-printers#/<br />

Suggestions for the long axis:<br />
<br />
<br />
- supportet Rails [https://www.dold-mechatronik.de/navi.php?a=45377&lang=eng#&gid=1&pid=1] would be nice for better stiffness and rigidity (see [https://www.youtube.com/watch?v=TSTThLM8s8o] at minute 0:30) . Makes a price difference of about 20,- EUR or less per m .<br />
<br />
* Instead of one 1"-shaft we could use two 1/2"-shafts to resemble the recent unversal axis design as is.<br />
<br />
* Or instead we can use just one 1"-shaft and place the stepper onto the carriage (like shapeoko) <br />
==> simplyfied end-pieces (they are only needed to fix the belt).<br />
<br />
<br />
<br />
<br />
- Universal Controler: Powerlolu as stepperdriver for heavier loads ?<br />
<br />
* Was already discussed on OSE in 2013, see [http://opensourceecology.org/wiki/Powerlolu]<br />
<br />

Suggestions for the long axis:<br />
<br />
<br />
- supportet Rails [https://www.dold-mechatronik.de/navi.php?a=45377&lang=eng#&gid=1&pid=1] would be nice for better stiffness and rigidity (see [https://www.youtube.com/watch?v=TSTThLM8s8o] at minute 0:30) . Makes a price difference of about 20,- EUR or less per m .<br />
<br />
* Instead of one 1"-shaft we could use two 1/2"-shafts to resemble the recent unversal axis design as is.<br />
<br />
* Or instead we can use just one 1"-shaft and place the stepper onto the carriage (like shapeoko) <br />
==> simplyfied end-pieces (they are only needed to fix the belt).<br />

<br />
* Check Step-Width, e.g. if the pulley has a different tooth-number and diameter stepwidth can be different, too<br />
<br />
* Check serial data-output for reasonable values before switching on the steppers (by the powersupply; the nano meanwhile can run "dry" by getting power from the USB-datacable). Do this with holding a metal plate in 0mm up to 30mm distance.<br />
<br />
* Dont start the steppers, without having the sensorhead installed and holding a metal-plate in front of it. Other wise it would produce zero-values and when trying to balance the algorithm would add more and more steps for compensation and the stepper would go through the wall.<br />
<br />
* make sure you have have connected the metal plate and as well the testrig-structure to the SHIELD-ground<br />
<br />
* Startposition is with 0mm distance. From this it will take a sample and then goes to 30mm and take another sample for calibration. Then it will go in a loop and trying to balance the distance around 15mm. I am going to upload a new firmware-version where endstop and jogwheel button will be integrated. Then the 0mm-position will be found automatically by homing. The 15mm will act as a default-value, but if you then push the button you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />

THCctrl, TB6600: In some wiring diagrams you find a common +5V line on EN,DIR,PUL (=STEP) in others they have a common ground. It seems that both is possible, see: [https://github.com/Arduinolibrary/TB6600_Stepper_Motor_Driver/raw/master/TB6600%20User%20Guide%20V1.2.pdf], [https://www.dfrobot.com/wiki/index.php/TB6600_Stepper_Motor_Driver_SKU:_DRI0043] and the links in [http://opensourceecology.org/wiki/Chas_log#May_30_2017 Chas' log].<br />
<br />
<br />
<br />
In RAMPS-like configurations it is often seen as common-ground connection [http://www.zyltech.com/tb6600.html] and sometimes with EN left unconnected. I assume its ok to connect EN, because otherwise the state of the stepper cannot be controlled externally. EN means that the stepper is active and draws current even if it doesnt move (and therefore getting warm). But there can be situations where its safe to inactivate that, e.g. wehn a 3Dprinter disables the steppers as soon as the print is finished. So this should be manageable by the controler.<br />

Idea to make a D3D-workshop completely relaxed: Just preproduce a number of printers and calibrate them perfectly. If someone doesnt get its own one ready during the course he can take a readymate one. So the promise "you get out here with a running printer" can be easily fullfilled and the workshop is completely free from any stress and totally relaxed (= best learning conditions)<br />
<br />
An interesting extension to this idea could be to let any class produce the printers for the next class (and take home a printer from the last class). So any printer creator becomes a kind of responsible godfather to someone elses printer (social relation ;)) Dont know whether the attendees really want that (but one could ask them; the surplus bonus is a nicely calibrated and perfectly running printer).<br />

Lesson learned: I tried in Kicad unsuccessfull different ways to import the 3d .wrl-files automatically, eg. by environment path-variable $KISYS3DMOD, but it is however possible to assign manually a 3d-form towards a footprint by editing its parameters (right mouseclick over footprint, then choose the footprint and in its 3d-settings the "add form" button) and let it point towards your local library-path .wrl-file. There you can also correct wrong orientations of the object, e.g. in a diode.<br />

It seems that both is possible, see: [https://github.com/Arduinolibrary/TB6600_Stepper_Motor_Driver/raw/master/TB6600%20User%20Guide%20V1.2.pdf], [https://www.dfrobot.com/wiki/index.php/TB6600_Stepper_Motor_Driver_SKU:_DRI0043] and the links in [http://opensourceecology.org/wiki/Chas_log#May_30_2017 Chas' log].<br />
<br />
<br />
<br />
In RAMPS-like configurations it is often seen as common-ground connection [http://www.zyltech.com/tb6600.html] and sometimes with EN left unconnected. I assume its ok to connect EN, because otherwise the state of the stepper cannot be controlled externally. EN means that the stepper is active and draws current even if it doesnt move (and therefore getting warm). But there can be situations where its safe to inactivate that, e.g. wehn a 3Dprinter disables the steppers as soon as the print is finished. So this should be manageable by the controler.<br />

Idea to make a D3D-workshop completely relaxed: Just preproduce a number of printers and calibrate them perfectly. If someone doesnt get its own one ready during the course he can take a readymate one. So the promise "you get out here with a running printer" can be easily fullfilled and the workshop is completely free from any stress and totally relaxed (= best learning conditions)<br />
<br />
An interesting extension to this idea could be to let any class produce the printers for the next class (and take home a printer from the last class). So any printer creator becomes a kind of responsible godfather to someone elses printer (social relation ;)) Dont know whether the attendees really want that (but one could ask them; the surplus bonus is a nicely calibrated and perfectly running printer).<br />

Lesson learned: I tried in Kicad unsuccessfull different ways to import the 3d .wrl-files automatically, eg. by environment path-variable $KISYS3DMOD, but it is however possible to assign manually a 3d-form towards a footprint by editing its parameters (right mouseclick over footprint, then choose the footprint and in its 3d-settings the "add form" button) and let it point towards your local library-path .wrl-file. There you can also correct wrong orientations of the object, e.g. in a diode.<br />

- Some checkpoints when trying to make the new pcb running:<br />
<br />
<br />
* Start with a testrig (a single D3D-axis), dont mount it immediately to the torchtable without prior testing<br />
<br />
* Check Step-Width, e.g. if the pulley has a different tooth-number and diameter stepwidth can be different, too<br />
<br />
* Check serial data-output for reasonable values before switching on the steppers (by the powersupply; the nano meanwhile can run "dry" by getting power from the USB-datacable). Do this with holding a metal plate in 0mm up to 30mm distance.<br />
<br />
* Dont start the steppers, without having the sensorhead installed and holding a metal-plate in front of it. Other wise it would produce zero-values and when trying to balance the algorithm would add more and more steps for compensation and the stepper would go through the wall.<br />
<br />
* make sure you have have connected the metal plate and as well the testrig-structure to the SHIELD-ground<br />
<br />
* Startposition is with 0mm distance. From this it will take a sample and then goes to 30mm and take another sample for calibration. Then it will go in a loop and trying to balance the distance around 15mm. I am going to upload a new firmware-version where endstop and jogwheel button will be integrated. Then the 0mm-position will be found automatically by homing. The 15mm will act as a default-value, but if you then push the button you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel.

THCctrl, TB6600: In some wiring diagrams you find a common +5V line on EN,DIR,PUL (=STEP) in others they have a common ground. It seems that both is possible, see: [https://github.com/Arduinolibrary/TB6600_Stepper_Motor_Driver/raw/master/TB6600%20User%20Guide%20V1.2.pdf], [https://www.dfrobot.com/wiki/index.php/TB6600_Stepper_Motor_Driver_SKU:_DRI0043] and the links in [http://opensourceecology.org/wiki/Chas_log#May_30_2017 Chas' log].<br />

<br />
<br />
In RAMPS-like configurations it is often seen as common-ground connection [http://www.zyltech.com/tb6600.html] and sometimes with EN left unconnected. I assume its ok to connect EN, because otherwise the state of the stepper cannot be controlled externally. EN means that the stepper is active and draws current even if it doesnt move (and therefore getting warm). But there can be situations where its safe to inactivate that, e.g. wehn a 3Dprinter disables the steppers as soon as the print is finished. So this should be manageable by the controler.<br />

Idea to make a D3D-workshop completely relaxed: Just preproduce a number of printers and calibrate them perfectly. If someone doesnt get its own one ready during the course he can take a readymate one. So the promise "you get out here with a running printer" can be easily fullfilled and the workshop is completely free from any stress and totally relaxed (= best learning conditions)<br />
<br />
An interesting extension to this idea could be to let any class produce the printers for the next class (and take home a printer from the last class). So any printer creator becomes a kind of responsible godfather to someone elses printer (social relation ;)) Dont know whether the attendees really want that (but one could ask them; the surplus bonus is a nicely calibrated and perfectly running printer).<br />

THCctrl, TB6600: In some wiring diagrams you find a common +5V line on EN,DIR,PUL (=STEP) in others they have a common ground. It seems that both is possible, see: [https://github.com/Arduinolibrary/TB6600_Stepper_Motor_Driver/raw/master/TB6600%20User%20Guide%20V1.2.pdf], [https://www.dfrobot.com/wiki/index.php/TB6600_Stepper_Motor_Driver_SKU:_DRI0043] and the links in [http://opensourceecology.org/wiki/Chas_log#May_30_2017 Chas' log].<br />
<br />
<br />
<br />
In RAMPS-like configurations it is often seen as common-ground connection [http://www.zyltech.com/tb6600.html] and sometimes with EN left unconnected. I assume its ok to connect EN, because otherwise the state of the stepper cannot be controlled externally. EN means that the stepper is active and draws current even if it doesnt move (and therefore getting warm). But there can be situations where its safe to inactivate that, e.g. wehn a 3Dprinter disables the steppers as soon as the print is finished. So this should be manageable by the controler.<br />

Idea to make a D3D-workshop completely relaxed: Just preproduce a number of printers and calibrate them perfectly. If someone doesnt get its own one ready during the course he can take a readymate one. So the promise "you get out here with a running printer" can be easily fullfilled and the workshop is completely free from any stress and totally relaxed (= best learning conditions)<br />
<br />
An interesting extension to this idea could be to let any class produce the printers for the next class (and take home a printer from the last class). So any printer creator becomes a kind of responsible godfather to someone elses printer (social relation ;)) Dont know whether the attendees really want that (but one could ask them; the surplus bonus is a nicely calibrated and perfectly running printer).<br />

Lesson learned: I tried in Kicad unsuccessfull different ways to import the 3d .wrl-files automatically, eg. by environment path-variable $KISYS3DMOD, but it is however possible to assign manually a 3d-form towards a footprint by editing its parameters (right mouseclick over footprint, then choose the footprint and in its 3d-settings the "add form" button) and let it point towards your local library-path .wrl-file. There you can also correct wrong orientations of the object, e.g. in a diode.<br />

Trying to re-use Pauls KiCad-Files run into the problem of beeing an older Version, what means all links are broken, see all the question marks in<br />
<br />
<gallery widths="360" perrow="1" caption="Reimport-problem on older Kicad files"><br />
Os_log_23.05.2017_reimport_problem.png| All default parts are in the newer Kicad version replaced by smaller ones, so the links are broken<br />
</gallery><br />
<br />
This is a known problem and theoretically there exists a way to fix it, see [https://rheingoldheavy.com/new-stable-kicad-10-steps-to-import-an-old-kicad-project/ https://rheingoldheavy.com/new-stable-kicad-10-steps-to-import-an-old-kicad-project/], but its way to complicated to go through this procedure. Meaning, since Pauls circuit is not too complicated its probably far less work to simply rebuild it from scratch.<br />
<br />

<br />
what about mechanical probing ? https://www.indiegogo.com/projects/bltouch-auto-bed-leveling-sensor-for-3d-printers#/<br />
Answer: probably not well suited because of the heat.<br />

Suggestions for the long axis:<br />
<br />
<br />
- supportet Rails [https://www.dold-mechatronik.de/navi.php?a=45377&lang=eng#&gid=1&pid=1] would be nice for better stiffness and rigidity (see [https://www.youtube.com/watch?v=TSTThLM8s8o] at minute 0:30) . Makes a price difference of about 20,- EUR or less per m .<br />
<br />
* Instead of one 1"-shaft we could use two 1/2"-shafts to resemble the recent unversal axis design as is.<br />
<br />
* Or instead we can use just one 1"-shaft and place the stepper onto the carriage (like shapeoko) <br />
==> simplyfied end-pieces (they are only needed to fix the belt).<br />
<br />
<br />
<br />
<br />

- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s with MPPT-20A Charge-Controler and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />
<br />
<br />
Solarbox-Specs:<br />
<br />
* 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)<br />
<br />
* suited for about 400Wp Solarpanel-input (or more with minor mods)<br />
<br />
* Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU<br />
<br />
* Solar-Charge-Controler: MPPT, up to 20A<br />
<br />
* dimensions about 44 x 32 x 20 cm<br />
<br />
* Inverter: Victron Phoenix 12/350<br />

<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- today i received an order from a special material filament named "Iglidur I150 Tribo-Filament" from Igus [http://www.igus.de/product/12404]. This is specially suited for 3dprinting sliding parts and is about 50 times less abrasive than ABS.<br />
<br />
I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />
<br />
<br />
Solarbox-Specs:<br />
<br />
* 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)<br />
<br />
* suited for about 400Wp Solarpanel-input (or more with minor mods)<br />
<br />
* Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU<br />
<br />
* Solar-Charge-Controler: MPPT, up to 20A<br />
<br />
* dimensions about 44 x 32 x 20 cm<br />
<br />
* Inverter: Victron Phoenix 12/350<br />

<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />
<br />
<br />
Solarbox-Specs:<br />
<br />
* 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)<br />
<br />
* suited for about 400Wp Solarpanel-input (or more with minor mods)<br />
<br />
* Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU<br />
<br />
* Solar-Charge-Controler: MPPT, up to 20A<br />
<br />
* dimensions about 44 x 32 x 20 cm<br />
<br />
* Inverter: Victron Phoenix 12/350<br />

<br />
<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />
<br />
<br />
Solarbox-Specs:<br />
<br />
* 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)<br />
<br />
* suited for about 400Wp Solarpanel-input (or more with minor mods)<br />
<br />
* Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU<br />
<br />
* Solar-Charge-Controler: MPPT, up to 20A<br />
<br />
* dimensions about 44 x 32 x 20 cm<br />
<br />
* Inverter: Victron Phoenix 12/350<br />

- some Slack-discussions and testing on the Duniter/Gt1 system with Lex and Josh<br />
<br />

<br />
- attended TorchTable Workshop online for kicad walkthrough TorchHeightCTRL pbc and Shanes kicad tutorial<br />
<br />
<br />
<br />
<br />
= '''Tue Oct 10, 2017''' =<br />
<br />
- Made Video that shows how to deploy the TorchHeightCTRL_V.02 sources from Github [https://github.com/case06/TorchHeightCTRL] on Kicad. <br />
<br />
See on youtube https://www.youtube.com/watch?v=v-nhG5vuZW0<br />
<br />
- installed and tested slack<br />
<br />
<br />
<br />
<br />
<br />
= '''Tue Oct 03, 2017''' =<br />
<br />
<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

<br />
I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />
<br />
<br />
Solarbox-Specs:<br />
<br />
* 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)<br />
<br />
* Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU<br />
<br />
* Solar-Charge-Controler: MPPT, up to 20A<br />
<br />
* dimensions about 44 x 32 x 20 cm<br />
<br />
* Inverter: Victron Phoenix 12/350<br />

- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />

I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />

Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />

- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />
<br />
Solarbox-Specs:<br />
<br />
- 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)<br />
<br />
- Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU<br />
<br />
- Solar-Charge-Controler: MPPT, up to 20A<br />
<br />
- dimensions about 44 x 32 x 20 cm<br />
<br />
- Inverter: Victron Phoenix 12/350<br />

<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.<br />
<br />
Solarbox-Specs:<br />
<br />
- 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)<br />
- Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU<br />
- Solar-Charge-Controler: MPPT, up to 20A<br />
- dimensions about 44 x 32 x 20 cm<br />
- Inverter: Victron Phoenix 12/350<br />

<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad<br />
<br />

<br />

<br />
<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

<br />
<br />

<br />
- Made Video that shows how to deploy the TorchHeightCTRL_V.02 sources from Github [https://github.com/case06/TorchHeightCTRL] on Kicad. <br />
<br />
See on youtube https://www.youtube.com/watch?v=v-nhG5vuZW0<br />

<br />
<br />
<br />
= '''Tue Oct 03, 2017''' =<br />
<br />
<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

= Automatic capacitive sensing version of CNC Torch Table Height Controller =<br />
<br />
This is the automatic height levelling version based on the new TorchHeightCTRL_V.02 pcb. (All Sources on GitHub: [[https://github.com/case06/TorchHeightCTRL]])<br />
<br />
<br />
== Design rationale ==<br />
<br />
The new pcb is an all-in-one board, that adds some peripheral interfaces to the application, like for endstop or a future direct user interface (Display).<br />
<br />
In the automated version the 0mm-distance / start-position should be found automatically by homing. <br />
From this it will take a sample and then goes to 30mm height and take another sample for calibration. Then it will go into a loop and trying to balance the distance around a pre-set default-value of 15mm. But if you then push the button of the jogwheel you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />

[[File:Os_THC02_wiringb.png|1024px]]<br />
<br />
<br />
=== Power Supply ===<br />
'''Warning: The phoenix-contact powersupply connector has NOT the same configuration than the connector of the same type on RAMPS-boards !!!'''<br />
<br />
Dont use the plug of a powersupply that was previously configured for use with a RAMPS-board and has 2 x 12V. The TorchHeightCTRL_V02 board has 1 x 5V and 1 x 12V and will be blown immedately if you give 12V to the 5V line !!!<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring PowerSupply"><br />
Os_THC02_wiring_ps5v.png | Connect 5V (red) and GND (black) from a PC-powersupply to the Phoenix Contact connector on the pcb as shown in the picture. Its a 4-pole connector, but leave two pins not connected (these are normally for 12V but its better to connect the TB6600 directly with the 12V)<br />
Os_THC02_wiring_ps12v.png | Use another string from the Powersupply and connect a 12V line directly with the TB6600, with 12V (yellow) to VCC and GND (black) to GND)<br />
</gallery><br />
<br />
<br />
=== TB6600 ===<br />
<br />
The TB6600 gets connected to J3 on the TorchHeightCTRL_V.02 pcb.<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring TB6600"><br />
Os_THC02_wiring_j3.png | Connections from J3 to the TB6600: EN (blue) goes to ENA+(+5V), DIR (yellow) to DIR+(+5V), STEP (green) to PUL+(+5V) and one of the GNDs (orange; third pin from left to right on J3) to PUL-(PUL). <br />
Os_THC02_wiring_tb6600.png | It doesnt matter, which GND-pin you use, but make sure that on TB6600-side the remaining GND-pins are bridged/connected with the GND-pin that connects to J3. Here the pin ENA-(ENA) is bridged to DIR-(DIR) and then a second bridge goes from DIR-(DIR) to PUL-(PUL), which contains also the (orange) wire that connects to one GND on J3.<br />
Os_THC02_tb6600_switches.png | The switches-setup in a configuration for 1/8 microstepping with a 2.0 Ampere steppermotor<br />
</gallery><br />
<br />
<br />
The steppermotor pins on the TB6600 are labeled as B-, B+, A-, A+. I found, that at least for my motor the order must be B-, B+, A+, A-. Otherwise the motor is doing funny things. This may be different on other motors, but you can simply try it by exchanging A+ with A- or B+ with B -. See also the motor diagramm on [http://opensourceecology.org/wiki/File:Os_manthc_stepper_wiring1.png].<br />
<br />
The power lines should be connected directly with a 12V line of the powersuplly, as mentioned above.<br />
<br />
=== Rotary Encoder KY-040 ===<br />
<br />
The Rotary Eccoder pins GND, 5V, DT and CLK get connected with J7 on the pcb. If you turn the pcb that you can read the labl "J7 Jog" in the right orientation the pins on J7 are (from left to right): 5V, GND, DT, CLK.<br />
<br />
There is one more pin on the KY-040, labelled as "SW". This is a button-press-funktion. Unfortunately the pcb-design was initially intended for another type of rotary encoder, which had not this function, so its not incorporated in the original design. But there is however a workaround (without soldering) for now. The SW pin must be connected to one pin of the ICSP-port on top of the Arduino Nano. (Note: This pin is also part of the UEXT-port, which is not used now. But later we should replace it with another free pin, e.g. pin D9.)<br />
<br />

</gallery><br />
<br />
<br />
<br />
=== EndStop ===<br />
<br />
The mechanical EndStop gets connected to J5 on the PCB. The Pinout of J5 is (from left to right): GND, DATA, 5V.<br />
(Note that some commercial EndStops may have a different pinout ! You then have to reconfigure the DuPont-connector.)<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="EndStop"><br />

</gallery><br />
<br />
<br />
<br />
<br />
<br />
=== Capacitance-Sensor-Probe ===<br />
<br />
The SensorHead-Probe gets connected with a coaxial cable with BNC-connector, where the Sensing-Ring is connected to the inner wire. You can get an impression on how the probe is made from the video at [https://www.youtube.com/watch?v=XWiALcJwFw8].<br />
<br />
<br />
For getting reasonable signal quality, its important to connect the metal-plate (your workpiece) and also the metal-parts of the test-rig with the SHIELD-ground from the sensor-probe. This is the internal shield-pin of the AD7747 and this is NOT (!!!) identical with the overall GND of the pcb. Therefore it is connected seperately. (Note: In a possible next generation/iteration of the pcb there should become definitely an extra screw-terminal connector with about 3 or 4 SHIELD-ground pins implemented.)<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring Sensor-Probe"><br />
Os_THC02_wiring_sensor.png | SHIELD-ground can be obtained from the wire mesh shield or from the outer metal-parts of the BNC connector.<br />

<br />
== Firmware ==<br />
<br />
<br />
=== Switching modes ===<br />
<br />
The arduino firmware is kept as small and simple as possible and should therefore be easily adoptable to daily needs - whatever may turnout to be useful in the future practical work with the torchtable. But from here and as a starting point the programm-logic suggest a workflow, that is based on two modi: <br />
<br />
- the manual mode (where the height can be steered manually by turning a jog-wheel)<br />
<br />
- the "auto-balancing" mode (meaning: automatical height-adaption based on capacitance-sensing data)<br />
<br />
See testing-video on youtube [https://www.youtube.com/watch?v=ggtvRYIhge4&t=7s].<br />
<br />
<br />
<br />
<br />
=== Calibration ===<br />
<br />
When the program starts, there is an initiation phase used for the individual calibration of each run, like:<br />
<br />
- do a homing and therefore get your zero-position (using a mechanical endstop)<br />
<br />
- step upwards to a distance of 30mm and get your maximum height position (by counting steps) and measure the according capacitance value.<br />
<br />
- adjust the working-height automatically by counting steps to a default value (lets say 15mm)<br />
<br />
=== Manual mode ===<br />
<br />
Then the Mainloop starts, in the manual mode. Height is not changed, unless you turn the wheel. If you do so, you can re-adjust the working height to a new level, higher or deeper.<br />
<br />
<br />
If you press the Jogwheel down (like a button) you generally switch between the both modes. If you are currently in the manual mode, you will enter the auto-balancing mode (and vice versa).<br />
<br />
<br />
=== Autobalancing-mode ===<br />
<br />
The autobalancing runs in a loop (until the jogwheel will be pressed again):<br />
<br />
- measure capacitance data<br />
<br />
- calculate the deviation from the wanted working height<br />
<br />
- initiate a number of (motor-)steps to produce a correction-move<br />
<br />
<br />
<br />
=== Filters ===<br />
<br />
There are several places in the sourcecode, where filters and algorithms can be applied, either to achieve a better signal-quality, or influence the "behavior" of the overall-workflow, e.g. like the sensivity. You can define a certain range (e.g. plus or minus 2 aF) in which you consider an deviations as artifcats and dont react with a move. Otherwise you would never have a calm position but instead a jitter of doing permanently correction moves, even if the height of the underlying workpiece doesnt have changed. More about this on the discussion page [http://opensourceecology.org/wiki/Talk:CNC_Torch_Table_Z_Height_Control#Specific_Steps_for_Signal_Improving].<br />
<br />
<br />
<br />
=== Communication ===<br />
<br />
Serial output by USB-cable. This can be used for debugging while development, or in normal use transmit current capacitance-data to a host-monitoring programm on your desktop PC, that samples and visualizes graphically the height-levels of the run.<br />
<br />
It is also planned to communicate to a direct user interface (OLED keypad) by (software) I2C.<br />

*Maybe remove the need for a 5V charger? Can the whole circuit run on 12V? (<-- nope. The Atmel Atmega328 cpu needs 1.8 to 5V, see specs at [http://www.microchip.com/wwwproducts/en/ATmega328]. If you would feed the Nano with 12V you would only burn more energy on the 78M05 voltage regulator onboard.)<br />
<br />
<br />
== Kicad pcb layout ==<br />
<br />
See how to load the pcb sources from Github and into Kicad (using OSE Linux (or others)) on this instructional youtube-video: https://www.youtube.com/watch?v=v-nhG5vuZW0<br />
<br />
The single steps are:<br />
<br />
1. Start OSE Linux<br />
<br />
2. open a shell and type: cd /tmp<br />
<br />
3. There type: git clone https://github.com/case06/TorchHeightCTRL<br />
<br />
4. open Kicad and choose from the file menu "open project".<br />
<br />
5. in the upcoming mask go to and open /tmp/TorchHeightCTRL/torchctrl.pro<br />
<br />
6. in the top icon-bar of the project-window press the most left icon "Schematic editor".<br />
<br />
7. Probably a error-msg concerning a "linear.lib" occures, press "ok" and ignore it.<br />
<br />
8. In the upcoming scheme-editor window press on the right side of the top icon bar the second last icon "Start pcb-new"<br />
<br />
9. In the upcoming pcblayout-editor choose "3D-viewer" from the edit-menu.<br />
<br />
<br />
<br />
<br />
<br />
=== Outlook, Next Iteration V.03 ===<br />
<br />
Todo-List:<br />
<br />
- the SW-pin of the rotary encoder for the button-pressed-function should be directly implemented into the pcb. Mounting it on the ICSP-port of the nano was just a workaround because when i first made the design i ommitted it because i had another type of rotary encoder in mind which had no SW-pin. But now it should be integrated in the pcb.<br />
<br />
<br />
- J4 could/should be replaced with a bigger sized version of the phoenix connector. The smaller one was just simply a mistake of me, because it is rated only for a max. of 6A. I mean, we dont use it anyway now because we connect the TB6600 directly with the powersupply, but if we ever want to use it AND if you want to put more than just one Motor onto the driver (or if we simply want to use bigger motors) then 6A may be not sufficient.<br />
<br />
<br />
- add some terminals for shield-ground, for connecting crocodile clamps (very important for reducing electrical noise !!!)<br />
<br />
<br />
- make all J3, J4, J7 larger? They are too small, needs a special screwdriver.<br />
<br />

= Manual adjustable version of CNC Torch Table Height Controller =<br />
<br />
This is a simple POC-version that allows a manual adjustment of the Z height by turning a jog wheel (see demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]). The wheel can be 3d-printed [https://www.thingiverse.com/thing:17404] and is connected to a rotary encoder of type KY-040.<br />
<br />

<br />
- demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]<br />
<br />
<br />
<br />
==Design Rationale==<br />
<br />
With this rig it should be possible to manually operate the torch table height by following its slowly moving and regulate the height personally. This can be useful even if in the full version there is a capacitive sensor doing automatically that task, but one may use it then for setting the starting height or use it in other applications where a frequent manual control is an appreciated option.<br />
<br />
The rotary encoder gives up to 20 pulses per revolution to an Arduino-Mega, which translates it into a number of motor steps and triggers these by a TB6600-based stepper-driver. A RAMPS 1.4 may act as a connection layer on top of the Arduino, but can also be omitted. We will show here which pins to wire on the Arduino and on the Ramps as well.<br />
<br />
The firmware consist only of a few lines of Arduino-code, which makes it easy to extend and modify.<br />

1. Ramps: Connect a 12V/5A-Line to the MSTBA4-Port an the Ramps, by using a phoenix-contact plug. This will provide power for Motor as well as board-power for the Arduino-Mega.<br />
<br />
2. Arduino standalone: The Arduino musst be supplied with 5V to 12V. This can be done by the USB-connection to a desktop-pc or by a standard wall-wart ac/dc-adaptor (5V, 2A) for the Mega.<br />
<br />
<br />
<br />
=== RotaryEncoder to Ramps/Arduino ===<br />
<br />
The KY-040 RotaryEncoder has 5 Lines: GND, +5V, SW, DT, CLK. Connect these either to the AUX2 port of the Ramps, or directly to the corresponding digital I/O ports on the Arduino-Mega. <br />
<br />
GND --> GND<br />
<br />
5V --> 5V<br />
<br />
SW --> D44<br />
<br />
DT --> D42<br />
<br />
CLK --> D40<br />

<br />
=== TB6600 to Ramps/Arduino, Motor and Power ===<br />
<br />
The TB6600 stepper driverhas three phoenix contact like connectors, <br />
<br />
- one 6-pin to the Ramps<br />
<br />
- one 4-pin to the motor<br />
<br />
- one 2 pin to power-supply<br />
<br />

<br />
<br />
<br />
'''The 6-pin connector''' has the lines ENA-, ENA+, DIR-, DIR+, PUL-, PUL+.<br />
<br />
Make a bridge between ENA- and DIR-, together with a second bridge from DIR- to PUL-. The PUL- contains a second cable which goes towards GND on the Ramps Extruder E0 port. So in total there are 4 wires going either to the Ramps or directly to the Arduino-Mega:<br />
<br />
1. Ramps:<br />
<br />
ENA+ --> EN<br />
<br />
DIR+ --> DIR<br />
<br />
PUL+ --> STEP<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />
2. Arduino-Mega:<br />
<br />
ENA+ --> D24<br />
<br />
DIR+ --> D28<br />
<br />
PUL+ --> D26<br />
<br />
PUL- --> GND<br />
<br />

<br />
<br />
<br />
<br />
'''The 4-pin connector''' has the lines A+, A-, B+, B-.<br />
<br />
In the case of a bipolar stepper motor with 4 wires two of them are the ends of one coil. Connect them like this:<br />
<br />

An example for a tested Nema17-stepper with 2A and 59Ncm holding torque is the 17HS19-2004S, see [http://www.omc-stepperonline.com/download/pdf/17HS19-2004S1.pdf], [http://www.omc-stepperonline.com/3d-printer-nema-17-stepper-motor-59ncm84ozin-2a-17hs192004s-p-18.html].<br />
<br />
<br />
<br />
<br />
<br />
'''The 2-pin connector''' has the lines 12V+, 12V-.<br />
<br />
Connect these to a power-supply which can deliver at least 5A. The TB6600 stepper driver is rated for up to 4A and 9-36V DC. That means you can instead of 12V also connect 24V or more towards it.<br />

= Automatic capacitive sensing version of CNC Torch Table Height Controller =<br />
<br />
This is the automatic height levelling version based on the new TorchHeightCTRL_V.02 pcb. (All Sources on GitHub: [[https://github.com/case06/TorchHeightCTRL]])<br />
<br />
<br />
== Design rationale ==<br />
<br />
The new pcb is an all-in-one board, that adds some peripheral interfaces to the application, like for endstop or a future direct user interface (Display).<br />
<br />
In the automated version the 0mm-distance / start-position should be found automatically by homing. <br />
From this it will take a sample and then goes to 30mm height and take another sample for calibration. Then it will go into a loop and trying to balance the distance around a pre-set default-value of 15mm. But if you then push the button of the jogwheel you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />

== Wiring Schema ==<br />

<br />
[[File:Os_THC02_wiringb.png|1024px]]<br />
<br />
<br />
=== Power Supply ===<br />
'''Warning: The phoenix-contact powersupply connector has NOT the same configuration than the connector of the same type on RAMPS-boards !!!'''<br />
<br />
Dont use the plug of a powersupply that was previously configured for use with a RAMPS-board and has 2 x 12V. The TorchHeightCTRL_V02 board has 1 x 5V and 1 x 12V and will be blown immedately if you give 12V to the 5V line !!!<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring PowerSupply"><br />
Os_THC02_wiring_ps5v.png | Connect 5V (red) and GND (black) from a PC-powersupply to the Phoenix Contact connector on the pcb as shown in the picture. Its a 4-pole connector, but leave two pins not connected (these are normally for 12V but its better to connect the TB6600 directly with the 12V)<br />
Os_THC02_wiring_ps12v.png | Use another string from the Powersupply and connect a 12V line directly with the TB6600, with 12V (yellow) to VCC and GND (black) to GND)<br />
</gallery><br />
<br />
<br />
=== TB6600 ===<br />
<br />
The TB6600 gets connected to J3 on the TorchHeightCTRL_V.02 pcb.<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring TB6600"><br />
Os_THC02_wiring_j3.png | Connections from J3 to the TB6600: EN (blue) goes to ENA+(+5V), DIR (yellow) to DIR+(+5V), STEP (green) to PUL+(+5V) and one of the GNDs (orange; third pin from left to right on J3) to PUL-(PUL). <br />
Os_THC02_wiring_tb6600.png | It doesnt matter, which GND-pin you use, but make sure that on TB6600-side the remaining GND-pins are bridged/connected with the GND-pin that connects to J3. Here the pin ENA-(ENA) is bridged to DIR-(DIR) and then a second bridge goes from DIR-(DIR) to PUL-(PUL), which contains also the (orange) wire that connects to one GND on J3.<br />
Os_THC02_tb6600_switches.png | The switches-setup in a configuration for 1/8 microstepping with a 2.0 Ampere steppermotor<br />
</gallery><br />
<br />
<br />
The steppermotor pins on the TB6600 are labeled as B-, B+, A-, A+. I found, that at least for my motor the order must be B-, B+, A+, A-. Otherwise the motor is doing funny things. This may be different on other motors, but you can simply try it by exchanging A+ with A- or B+ with B -. See also the motor diagramm on [http://opensourceecology.org/wiki/File:Os_manthc_stepper_wiring1.png].<br />
<br />
The power lines should be connected directly with a 12V line of the powersuplly, as mentioned above.<br />
<br />
=== Rotary Encoder KY-040 ===<br />
<br />
The Rotary Eccoder pins GND, 5V, DT and CLK get connected with J7 on the pcb. If you turn the pcb that you can read the labl "J7 Jog" in the right orientation the pins on J7 are (from left to right): 5V, GND, DT, CLK.<br />
<br />
There is one more pin on the KY-040, labelled as "SW". This is a button-press-funktion. Unfortunately the pcb-design was initially intended for another type of rotary encoder, which had not this function, so its not incorporated in the original design. But there is however a workaround (without soldering) for now. The SW pin must be connected to one pin of the ICSP-port on top of the Arduino Nano. (Note: This pin is also part of the UEXT-port, which is not used now. But later we should replace it with another free pin, e.g. pin D9.)<br />
<br />

Os_THC02_wiring_nano.png | See the 6-pole ICSP-port on top of the Arduino Nano. The most right pin in the top row, denoted as "18, PB4, pcint4, MISO", has to be connected with the pin SW on the KY-040<br />
</gallery><br />
<br />
<br />
<br />
=== EndStop ===<br />
<br />
The mechanical EndStop gets connected to J5 on the PCB. The Pinout of J5 is (from left to right): GND, DATA, 5V.<br />
(Note that some commercial EndStops may have a different pinout ! You then have to reconfigure the DuPont-connector.)<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="EndStop"><br />

</gallery><br />
<br />
<br />
<br />
<br />
<br />
=== Capacitance-Sensor-Probe ===<br />
<br />
The SensorHead-Probe gets connected with a coaxial cable with BNC-connector, where the Sensing-Ring is connected to the inner wire. You can get an impression on how the probe is made from the video at [https://www.youtube.com/watch?v=XWiALcJwFw8].<br />
<br />
<br />
For getting reasonable signal quality, its important to connect the metal-plate (your workpiece) and also the metal-parts of the test-rig with the SHIELD-ground from the sensor-probe. This is the internal shield-pin of the AD7747 and this is NOT (!!!) identical with the overall GND of the pcb. Therefore it is connected seperately. (Note: In a possible next generation/iteration of the pcb there should become definitely an extra screw-terminal connector with about 3 or 4 SHIELD-ground pins implemented.)<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring Sensor-Probe"><br />
Os_THC02_wiring_sensor.png | SHIELD-ground can be obtained from the wire mesh shield or from the outer metal-parts of the BNC connector.<br />
</gallery><br />
<br />
== Firmware ==<br />
<br />
<br />
=== Switching modes ===<br />
<br />
The arduino firmware is kept as small and simple as possible and should therefore be easily adoptable to daily needs - whatever may turnout to be useful in the future practical work with the torchtable. But from here and as a starting point the programm-logic suggest a workflow, that is based on two modi: <br />
<br />
- the manual mode (where the height can be steered manually by turning a jog-wheel)<br />
<br />
- the "auto-balancing" mode (meaning: automatical height-adaption based on capacitance-sensing data)<br />
<br />
See testing-video on youtube [https://www.youtube.com/watch?v=ggtvRYIhge4&t=7s].<br />
<br />
<br />
<br />
<br />
=== Calibration ===<br />
<br />
When the program starts, there is an initiation phase used for the individual calibration of each run, like:<br />
<br />
- do a homing and therefore get your zero-position (using a mechanical endstop)<br />
<br />
- step upwards to a distance of 30mm and get your maximum height position (by counting steps) and measure the according capacitance value.<br />
<br />
- adjust the working-height automatically by counting steps to a default value (lets say 15mm)<br />
<br />
=== Manual mode ===<br />
<br />
Then the Mainloop starts, in the manual mode. Height is not changed, unless you turn the wheel. If you do so, you can re-adjust the working height to a new level, higher or deeper.<br />
<br />
<br />
If you press the Jogwheel down (like a button) you generally switch between the both modes. If you are currently in the manual mode, you will enter the auto-balancing mode (and vice versa).<br />
<br />
<br />
=== Autobalancing-mode ===<br />
<br />
The autobalancing runs in a loop (until the jogwheel will be pressed again):<br />
<br />
- measure capacitance data<br />
<br />
- calculate the deviation from the wanted working height<br />
<br />
- initiate a number of (motor-)steps to produce a correction-move<br />
<br />
<br />
<br />
=== Filters ===<br />
<br />
There are several places in the sourcecode, where filters and algorithms can be applied, either to achieve a better signal-quality, or influence the "behavior" of the overall-workflow, e.g. like the sensivity. You can define a certain range (e.g. plus or minus 2 aF) in which you consider an deviations as artifcats and dont react with a move. Otherwise you would never have a calm position but instead a jitter of doing permanently correction moves, even if the height of the underlying workpiece doesnt have changed. More about this on the discussion page [http://opensourceecology.org/wiki/Talk:CNC_Torch_Table_Z_Height_Control#Specific_Steps_for_Signal_Improving].<br />
<br />
<br />
<br />
=== Communication ===<br />
<br />
Serial output by USB-cable. This can be used for debugging while development, or in normal use transmit current capacitance-data to a host-monitoring programm on your desktop PC, that samples and visualizes graphically the height-levels of the run.<br />
<br />
It is also planned to communicate to a direct user interface (OLED keypad) by (software) I2C.<br />

*Maybe remove the need for a 5V charger? Can the whole circuit run on 12V? (<-- nope. The Atmel Atmega328 cpu needs 1.8 to 5V, see specs at [http://www.microchip.com/wwwproducts/en/ATmega328]. If you would feed the Nano with 12V you would only burn more energy on the 78M05 voltage regulator onboard.)<br />

<br />
== Kicad pcb layout ==<br />
<br />
See how to load the pcb sources from Github and into Kicad (using OSE Linux (or others)) on this instructional youtube-video: https://www.youtube.com/watch?v=v-nhG5vuZW0<br />
<br />
The single steps are:<br />
<br />
1. Start OSE Linux<br />
<br />
2. open a shell and type: cd /tmp<br />
<br />
3. There type: git clone https://github.com/case06/TorchHeightCTRL<br />
<br />
4. open Kicad and choose from the file menu "open project".<br />
<br />
5. in the upcoming mask go to and open /tmp/TorchHeightCTRL/torchctrl.pro<br />
<br />
6. in the top icon-bar of the project-window press the most left icon "Schematic editor".<br />
<br />
7. Probably a error-msg concerning a "linear.lib" occures, press "ok" and ignore it.<br />
<br />
8. In the upcoming scheme-editor window press on the right side of the top icon bar the second last icon "Start pcb-new"<br />
<br />
9. In the upcoming pcblayout-editor choose "3D-viewer" from the edit-menu.<br />
<br />
<br />
<br />
<br />
<br />
=== Outlook, Next Iteration V.03 ===<br />
<br />
Todo-List:<br />
<br />
- the SW-pin of the rotary encoder for the button-pressed-function should be directly implemented into the pcb. Mounting it on the ICSP-port of the nano was just a workaround because when i first made the design i ommitted it because i had another type of rotary encoder in mind which had no SW-pin. But now it should be integrated in the pcb.<br />
<br />
<br />
- J4 could/should be replaced with a bigger sized version of the phoenix connector. The smaller one was just simply a mistake of me, because it is rated only for a max. of 6A. I mean, we dont use it anyway now because we connect the TB6600 directly with the powersupply, but if we ever want to use it AND if you want to put more than just one Motor onto the driver (or if we simply want to use bigger motors) then 6A may be not sufficient.<br />
<br />
<br />
- add some terminals for shield-ground, for connecting crocodile clamps (very important for reducing electrical noise !!!)<br />
<br />
<br />
- make all J3, J4, J7 larger? They are too small, needs a special screwdriver.<br />

= Manual adjustable version of CNC Torch Table Height Controller =<br />
<br />
This is a simple POC-version that allows a manual adjustment of the Z height by turning a jog wheel (see demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]). The wheel can be 3d-printed [https://www.thingiverse.com/thing:17404] and is connected to a rotary encoder of type KY-040.<br />

<br />
- demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]<br />
<br />
<br />
<br />
==Design Rationale==<br />
<br />
With this rig it should be possible to manually operate the torch table height by following its slowly moving and regulate the height personally. This can be useful even if in the full version there is a capacitive sensor doing automatically that task, but one may use it then for setting the starting height or use it in other applications where a frequent manual control is an appreciated option.<br />
<br />
The rotary encoder gives up to 20 pulses per revolution to an Arduino-Mega, which translates it into a number of motor steps and triggers these by a TB6600-based stepper-driver. A RAMPS 1.4 may act as a connection layer on top of the Arduino, but can also be omitted. We will show here which pins to wire on the Arduino and on the Ramps as well.<br />
<br />
The firmware consist only of a few lines of Arduino-code, which makes it easy to extend and modify.<br />

<br />
<br />
<br />
=== Power-supply to Ramps/Arduino ===<br />
<br />
1. Ramps: Connect a 12V/5A-Line to the MSTBA4-Port an the Ramps, by using a phoenix-contact plug. This will provide power for Motor as well as board-power for the Arduino-Mega.<br />
<br />
2. Arduino standalone: The Arduino musst be supplied with 5V to 12V. This can be done by the USB-connection to a desktop-pc or by a standard wall-wart ac/dc-adaptor (5V, 2A) for the Mega.<br />
<br />
<br />
<br />
=== RotaryEncoder to Ramps/Arduino ===<br />
<br />
The KY-040 RotaryEncoder has 5 Lines: GND, +5V, SW, DT, CLK. Connect these either to the AUX2 port of the Ramps, or directly to the corresponding digital I/O ports on the Arduino-Mega. <br />
<br />
GND --> GND<br />
<br />
5V --> 5V<br />
<br />
SW --> D44<br />
<br />
DT --> D42<br />
<br />
CLK --> D40<br />

<br />
=== TB6600 to Ramps/Arduino, Motor and Power ===<br />
<br />
The TB6600 stepper driverhas three phoenix contact like connectors, <br />
<br />
- one 6-pin to the Ramps<br />
<br />
- one 4-pin to the motor<br />
<br />
- one 2 pin to power-supply<br />
<br />
<br />

</gallery><br />
<br />
<br />
<br />
'''The 6-pin connector''' has the lines ENA-, ENA+, DIR-, DIR+, PUL-, PUL+.<br />
<br />
Make a bridge between ENA- and DIR-, together with a second bridge from DIR- to PUL-. The PUL- contains a second cable which goes towards GND on the Ramps Extruder E0 port. So in total there are 4 wires going either to the Ramps or directly to the Arduino-Mega:<br />
<br />
1. Ramps:<br />
<br />
ENA+ --> EN<br />
<br />
DIR+ --> DIR<br />
<br />
PUL+ --> STEP<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />
2. Arduino-Mega:<br />
<br />
ENA+ --> D24<br />
<br />
DIR+ --> D28<br />
<br />
PUL+ --> D26<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />

</gallery><br />
<br />
<br />
<br />
<br />
'''The 4-pin connector''' has the lines A+, A-, B+, B-.<br />
<br />
In the case of a bipolar stepper motor with 4 wires two of them are the ends of one coil. Connect them like this:<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2"><br />

</gallery><br />
<br />
<br />
An example for a tested Nema17-stepper with 2A and 59Ncm holding torque is the 17HS19-2004S, see [http://www.omc-stepperonline.com/download/pdf/17HS19-2004S1.pdf], [http://www.omc-stepperonline.com/3d-printer-nema-17-stepper-motor-59ncm84ozin-2a-17hs192004s-p-18.html].<br />
<br />
<br />
<br />
<br />
<br />
'''The 2-pin connector''' has the lines 12V+, 12V-.<br />
<br />
Connect these to a power-supply which can deliver at least 5A. The TB6600 stepper driver is rated for up to 4A and 9-36V DC. That means you can instead of 12V also connect 24V or more towards it.<br />

= Automatic capacitive sensing version of CNC Torch Table Height Controller =<br />
<br />
This is the automatic height levelling version based on the new TorchHeightCTRL_V.02 pcb. (All Sources on GitHub: [[https://github.com/case06/TorchHeightCTRL]])<br />
<br />
<br />
== Design rationale ==<br />
<br />
The new pcb is an all-in-one board, that adds some peripheral interfaces to the application, like for endstop or a future direct user interface (Display).<br />
<br />
In the automated version the 0mm-distance / start-position should be found automatically by homing. <br />
From this it will take a sample and then goes to 30mm height and take another sample for calibration. Then it will go into a loop and trying to balance the distance around a pre-set default-value of 15mm. But if you then push the button of the jogwheel you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />

<br />
<br />
=== Power Supply ===<br />
'''Warning: The phoenix-contact powersupply connector has NOT the same configuration than the connector of the same type on RAMPS-boards !!!'''<br />
<br />
Dont use the plug of a powersupply that was previously configured for use with a RAMPS-board and has 2 x 12V. The TorchHeightCTRL_V02 board has 1 x 5V and 1 x 12V and will be blown immedately if you give 12V to the 5V line !!!<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring PowerSupply"><br />
Os_THC02_wiring_ps5v.png | Connect 5V (red) and GND (black) from a PC-powersupply to the Phoenix Contact connector on the pcb as shown in the picture. Its a 4-pole connector, but leave two pins not connected (these are normally for 12V but its better to connect the TB6600 directly with the 12V)<br />
Os_THC02_wiring_ps12v.png | Use another string from the Powersupply and connect a 12V line directly with the TB6600, with 12V (yellow) to VCC and GND (black) to GND)<br />
</gallery><br />
<br />
<br />
=== TB6600 ===<br />
<br />
The TB6600 gets connected to J3 on the TorchHeightCTRL_V.02 pcb.<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring TB6600"><br />
Os_THC02_wiring_j3.png | Connections from J3 to the TB6600: EN (blue) goes to ENA+(+5V), DIR (yellow) to DIR+(+5V), STEP (green) to PUL+(+5V) and one of the GNDs (orange; third pin from left to right on J3) to PUL-(PUL). <br />
Os_THC02_wiring_tb6600.png | It doesnt matter, which GND-pin you use, but make sure that on TB6600-side the remaining GND-pins are bridged/connected with the GND-pin that connects to J3. Here the pin ENA-(ENA) is bridged to DIR-(DIR) and then a second bridge goes from DIR-(DIR) to PUL-(PUL), which contains also the (orange) wire that connects to one GND on J3.<br />
Os_THC02_tb6600_switches.png | The switches-setup in a configuration for 1/8 microstepping with a 2.0 Ampere steppermotor<br />
</gallery><br />
<br />
<br />
The steppermotor pins on the TB6600 are labeled as B-, B+, A-, A+. I found, that at least for my motor the order must be B-, B+, A+, A-. Otherwise the motor is doing funny things. This may be different on other motors, but you can simply try it by exchanging A+ with A- or B+ with B -. See also the motor diagramm on [http://opensourceecology.org/wiki/File:Os_manthc_stepper_wiring1.png].<br />
<br />
The power lines should be connected directly with a 12V line of the powersuplly, as mentioned above.<br />
<br />
=== Rotary Encoder KY-040 ===<br />
<br />
The Rotary Eccoder pins GND, 5V, DT and CLK get connected with J7 on the pcb. If you turn the pcb that you can read the labl "J7 Jog" in the right orientation the pins on J7 are (from left to right): 5V, GND, DT, CLK.<br />
<br />
There is one more pin on the KY-040, labelled as "SW". This is a button-press-funktion. Unfortunately the pcb-design was initially intended for another type of rotary encoder, which had not this function, so its not incorporated in the original design. But there is however a workaround (without soldering) for now. The SW pin must be connected to one pin of the ICSP-port on top of the Arduino Nano. (Note: This pin is also part of the UEXT-port, which is not used now. But later we should replace it with another free pin, e.g. pin D9.)<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring KY-040"><br />
Os_THC02_wiring_j7.png | J7, from left to right: 5V, GND, DT, CLK<br />
Os_THC02_wiring_nano.png | See the 6-pole ICSP-port on top of the Arduino Nano. The most right pin in the top row, denoted as "18, PB4, pcint4, MISO", has to be connected with the pin SW on the KY-040<br />
</gallery><br />
<br />
<br />
<br />
=== EndStop ===<br />
<br />
The mechanical EndStop gets connected to J5 on the PCB. The Pinout of J5 is (from left to right): GND, DATA, 5V.<br />
(Note that some commercial EndStops may have a different pinout ! You then have to reconfigure the DuPont-connector.)<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="EndStop"><br />

</gallery><br />
<br />
<br />
<br />
<br />
<br />
=== Capacitance-Sensor-Probe ===<br />
<br />
The SensorHead-Probe gets connected with a coaxial cable with BNC-connector, where the Sensing-Ring is connected to the inner wire. You can get an impression on how the probe is made from the video at [https://www.youtube.com/watch?v=XWiALcJwFw8].<br />
<br />
<br />
For getting reasonable signal quality, its important to connect the metal-plate (your workpiece) and also the metal-parts of the test-rig with the SHIELD-ground from the sensor-probe. This is the internal shield-pin of the AD7747 and this is NOT (!!!) identical with the overall GND of the pcb. Therefore it is connected seperately. (Note: In a possible next generation/iteration of the pcb there should become definitely an extra screw-terminal connector with about 3 or 4 SHIELD-ground pins implemented.)<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring Sensor-Probe"><br />
Os_THC02_wiring_sensor.png | SHIELD-ground can be obtained from the wire mesh shield or from the outer metal-parts of the BNC connector.<br />
</gallery><br />
<br />
== Firmware ==<br />
<br />
<br />
=== Switching modes ===<br />
<br />
The arduino firmware is kept as small and simple as possible and should therefore be easily adoptable to daily needs - whatever may turnout to be useful in the future practical work with the torchtable. But from here and as a starting point the programm-logic suggest a workflow, that is based on two modi: <br />
<br />
- the manual mode (where the height can be steered manually by turning a jog-wheel)<br />
<br />
- the "auto-balancing" mode (meaning: automatical height-adaption based on capacitance-sensing data)<br />
<br />
See testing-video on youtube [https://www.youtube.com/watch?v=ggtvRYIhge4&t=7s].<br />
<br />
<br />
<br />
<br />
=== Calibration ===<br />
<br />
When the program starts, there is an initiation phase used for the individual calibration of each run, like:<br />
<br />
- do a homing and therefore get your zero-position (using a mechanical endstop)<br />
<br />
- step upwards to a distance of 30mm and get your maximum height position (by counting steps) and measure the according capacitance value.<br />
<br />
- adjust the working-height automatically by counting steps to a default value (lets say 15mm)<br />
<br />
=== Manual mode ===<br />
<br />
Then the Mainloop starts, in the manual mode. Height is not changed, unless you turn the wheel. If you do so, you can re-adjust the working height to a new level, higher or deeper.<br />
<br />
<br />
If you press the Jogwheel down (like a button) you generally switch between the both modes. If you are currently in the manual mode, you will enter the auto-balancing mode (and vice versa).<br />
<br />
<br />
=== Autobalancing-mode ===<br />
<br />
The autobalancing runs in a loop (until the jogwheel will be pressed again):<br />
<br />
- measure capacitance data<br />
<br />
- calculate the deviation from the wanted working height<br />
<br />
- initiate a number of (motor-)steps to produce a correction-move<br />
<br />
<br />
<br />
=== Filters ===<br />
<br />
There are several places in the sourcecode, where filters and algorithms can be applied, either to achieve a better signal-quality, or influence the "behavior" of the overall-workflow, e.g. like the sensivity. You can define a certain range (e.g. plus or minus 2 aF) in which you consider an deviations as artifcats and dont react with a move. Otherwise you would never have a calm position but instead a jitter of doing permanently correction moves, even if the height of the underlying workpiece doesnt have changed. More about this on the discussion page [http://opensourceecology.org/wiki/Talk:CNC_Torch_Table_Z_Height_Control#Specific_Steps_for_Signal_Improving].<br />
<br />
<br />
<br />
=== Communication ===<br />
<br />
Serial output by USB-cable. This can be used for debugging while development, or in normal use transmit current capacitance-data to a host-monitoring programm on your desktop PC, that samples and visualizes graphically the height-levels of the run.<br />
<br />
It is also planned to communicate to a direct user interface (OLED keypad) by (software) I2C.<br />

*Maybe remove the need for a 5V charger? Can the whole circuit run on 12V? (<-- nope. The Atmel Atmega328 cpu needs 1.8 to 5V, see specs at [http://www.microchip.com/wwwproducts/en/ATmega328]. If you would feed the Nano with 12V you would only burn more energy on the 78M05 voltage regulator onboard.)<br />

<br />
See how to load the pcb sources from Github and into Kicad (using OSE Linux (or others)) on this instructional youtube-video: https://www.youtube.com/watch?v=v-nhG5vuZW0<br />
<br />
The single steps are:<br />
<br />
1. Start OSE Linux<br />
<br />
2. open a shell and type: cd /tmp<br />
<br />
3. There type: git clone https://github.com/case06/TorchHeightCTRL<br />
<br />
4. open Kicad and choose from the file menu "open project".<br />
<br />
5. in the upcoming mask go to and open /tmp/TorchHeightCTRL/torchctrl.pro<br />
<br />
6. in the top icon-bar of the project-window press the most left icon "Schematic editor".<br />
<br />
7. Probably a error-msg concerning a "linear.lib" occures, press "ok" and ignore it.<br />
<br />
8. In the upcoming scheme-editor window press on the right side of the top icon bar the second last icon "Start pcb-new"<br />
<br />
9. In the upcoming pcblayout-editor choose "3D-viewer" from the edit-menu.<br />
<br />
<br />
<br />
<br />
<br />
=== Outlook, Next Iteration V.03 ===<br />
<br />
Todo-List:<br />
<br />
- the SW-pin of the rotary encoder for the button-pressed-function should be directly implemented into the pcb. Mounting it on the ICSP-port of the nano was just a workaround because when i first made the design i ommitted it because i had another type of rotary encoder in mind which had no SW-pin. But now it should be integrated in the pcb.<br />
<br />
<br />
- J4 could/should be replaced with a bigger sized version of the phoenix connector. The smaller one was just simply a mistake of me, because it is rated only for a max. of 6A. I mean, we dont use it anyway now because we connect the TB6600 directly with the powersupply, but if we ever want to use it AND if you want to put more than just one Motor onto the driver (or if we simply want to use bigger motors) then 6A may be not sufficient.<br />
<br />
<br />
- one or two other small things that i dont remember yet ;)<br />
<br />
<br />
- make all J3, J4, J7 larger? They are too small, needs a special screwdriver.<br />

= Manual adjustable version of CNC Torch Table Height Controller =<br />
<br />
This is a simple POC-version that allows a manual adjustment of the Z height by turning a jog wheel (see demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]). The wheel can be 3d-printed [https://www.thingiverse.com/thing:17404] and is connected to a rotary encoder of type KY-040.<br />
<br />

<br />
- demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]<br />
<br />
<br />
<br />
==Design Rationale==<br />
<br />
With this rig it should be possible to manually operate the torch table height by following its slowly moving and regulate the height personally. This can be useful even if in the full version there is a capacitive sensor doing automatically that task, but one may use it then for setting the starting height or use it in other applications where a frequent manual control is an appreciated option.<br />
<br />
The rotary encoder gives up to 20 pulses per revolution to an Arduino-Mega, which translates it into a number of motor steps and triggers these by a TB6600-based stepper-driver. A RAMPS 1.4 may act as a connection layer on top of the Arduino, but can also be omitted. We will show here which pins to wire on the Arduino and on the Ramps as well.<br />
<br />
The firmware consist only of a few lines of Arduino-code, which makes it easy to extend and modify.<br />

== Wiring ==<br />
<br />
There are 3 kind of connections:<br />
<br />
- Power-supply to Ramps/Arduino<br />
<br />
- Rotary Encoder to Ramps/Arduino<br />
<br />
- TB6600 to Ramps/Arduino<br />

</gallery><br />
<br />
<br />
<br />
<br />
=== Power-supply to Ramps/Arduino ===<br />
<br />
1. Ramps: Connect a 12V/5A-Line to the MSTBA4-Port an the Ramps, by using a phoenix-contact plug. This will provide power for Motor as well as board-power for the Arduino-Mega.<br />
<br />
2. Arduino standalone: The Arduino musst be supplied with 5V to 12V. This can be done by the USB-connection to a desktop-pc or by a standard wall-wart ac/dc-adaptor (5V, 2A) for the Mega.<br />
<br />
<br />
<br />
=== RotaryEncoder to Ramps/Arduino ===<br />
<br />
The KY-040 RotaryEncoder has 5 Lines: GND, +5V, SW, DT, CLK. Connect these either to the AUX2 port of the Ramps, or directly to the corresponding digital I/O ports on the Arduino-Mega. <br />
<br />
GND --> GND<br />
<br />
5V --> 5V<br />
<br />
SW --> D44<br />
<br />
DT --> D42<br />
<br />
CLK --> D40<br />
<br />

</gallery><br />
<br />
=== TB6600 to Ramps/Arduino, Motor and Power ===<br />
<br />
The TB6600 stepper driverhas three phoenix contact like connectors, <br />
<br />
- one 6-pin to the Ramps<br />
<br />
- one 4-pin to the motor<br />
<br />
- one 2 pin to power-supply<br />
<br />
<br />

</gallery><br />
<br />
<br />
<br />
'''The 6-pin connector''' has the lines ENA-, ENA+, DIR-, DIR+, PUL-, PUL+.<br />
<br />
Make a bridge between ENA- and DIR-, together with a second bridge from DIR- to PUL-. The PUL- contains a second cable which goes towards GND on the Ramps Extruder E0 port. So in total there are 4 wires going either to the Ramps or directly to the Arduino-Mega:<br />
<br />
1. Ramps:<br />
<br />
ENA+ --> EN<br />
<br />
DIR+ --> DIR<br />
<br />
PUL+ --> STEP<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />
2. Arduino-Mega:<br />
<br />
ENA+ --> D24<br />
<br />
DIR+ --> D28<br />
<br />
PUL+ --> D26<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />

</gallery><br />
<br />
<br />
<br />
<br />
'''The 4-pin connector''' has the lines A+, A-, B+, B-.<br />
<br />
In the case of a bipolar stepper motor with 4 wires two of them are the ends of one coil. Connect them like this:<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2"><br />

<br />
<br />
An example for a tested Nema17-stepper with 2A and 59Ncm holding torque is the 17HS19-2004S, see [http://www.omc-stepperonline.com/download/pdf/17HS19-2004S1.pdf], [http://www.omc-stepperonline.com/3d-printer-nema-17-stepper-motor-59ncm84ozin-2a-17hs192004s-p-18.html].<br />
<br />
<br />
<br />
<br />
<br />
'''The 2-pin connector''' has the lines 12V+, 12V-.<br />
<br />
Connect these to a power-supply which can deliver at least 5A. The TB6600 stepper driver is rated for up to 4A and 9-36V DC. That means you can instead of 12V also connect 24V or more towards it.<br />

= Automatic capacitive sensing version of CNC Torch Table Height Controller =<br />
<br />
This is the automatic height levelling version based on the new TorchHeightCTRL_V.02 pcb. (All Sources on GitHub: [[https://github.com/case06/TorchHeightCTRL]])<br />
<br />
<br />
== Design rationale ==<br />
<br />
The new pcb is an all-in-one board, that adds some peripheral interfaces to the application, like for endstop or a future direct user interface (Display).<br />
<br />
In the automated version the 0mm-distance / start-position should be found automatically by homing. <br />
From this it will take a sample and then goes to 30mm height and take another sample for calibration. Then it will go into a loop and trying to balance the distance around a pre-set default-value of 15mm. But if you then push the button of the jogwheel you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />

=== Power Supply ===<br />
'''Warning: The phoenix-contact powersupply connector has NOT the same configuration than the connector of the same type on RAMPS-boards !!!'''<br />
<br />
Dont use the plug of a powersupply that was previously configured for use with a RAMPS-board and has 2 x 12V. The TorchHeightCTRL_V02 board has 1 x 5V and 1 x 12V and will be blown immedately if you give 12V to the 5V line !!!<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring PowerSupply"><br />
Os_THC02_wiring_ps5v.png | Connect 5V (red) and GND (black) from a PC-powersupply to the Phoenix Contact connector on the pcb as shown in the picture. Its a 4-pole connector, but leave two pins not connected (these are normally for 12V but its better to connect the TB6600 directly with the 12V)<br />
Os_THC02_wiring_ps12v.png | Use another string from the Powersupply and connect a 12V line directly with the TB6600, with 12V (yellow) to VCC and GND (black) to GND)<br />
</gallery><br />
<br />
<br />
=== TB6600 ===<br />
<br />
The TB6600 gets connected to J3 on the TorchHeightCTRL_V.02 pcb.<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring TB6600"><br />
Os_THC02_wiring_j3.png | Connections from J3 to the TB6600: EN (blue) goes to ENA+(+5V), DIR (yellow) to DIR+(+5V), STEP (green) to PUL+(+5V) and one of the GNDs (orange; third pin from left to right on J3) to PUL-(PUL). <br />
Os_THC02_wiring_tb6600.png | It doesnt matter, which GND-pin you use, but make sure that on TB6600-side the remaining GND-pins are bridged/connected with the GND-pin that connects to J3. Here the pin ENA-(ENA) is bridged to DIR-(DIR) and then a second bridge goes from DIR-(DIR) to PUL-(PUL), which contains also the (orange) wire that connects to one GND on J3.<br />
Os_THC02_tb6600_switches.png | The switches-setup in a configuration for 1/8 microstepping with a 2.0 Ampere steppermotor<br />
</gallery><br />
<br />
<br />
The steppermotor pins on the TB6600 are labeled as B-, B+, A-, A+. I found, that at least for my motor the order must be B-, B+, A+, A-. Otherwise the motor is doing funny things. This may be different on other motors, but you can simply try it by exchanging A+ with A- or B+ with B -. See also the motor diagramm on [http://opensourceecology.org/wiki/File:Os_manthc_stepper_wiring1.png].<br />
<br />
The power lines should be connected directly with a 12V line of the powersuplly, as mentioned above.<br />
<br />
=== Rotary Encoder KY-040 ===<br />
<br />
The Rotary Eccoder pins GND, 5V, DT and CLK get connected with J7 on the pcb. If you turn the pcb that you can read the labl "J7 Jog" in the right orientation the pins on J7 are (from left to right): 5V, GND, DT, CLK.<br />
<br />
There is one more pin on the KY-040, labelled as "SW". This is a button-press-funktion. Unfortunately the pcb-design was initially intended for another type of rotary encoder, which had not this function, so its not incorporated in the original design. But there is however a workaround (without soldering) for now. The SW pin must be connected to one pin of the ICSP-port on top of the Arduino Nano. (Note: This pin is also part of the UEXT-port, which is not used now. But later we should replace it with another free pin, e.g. pin D9.)<br />
<br />

</gallery><br />
<br />
<br />
<br />
=== EndStop ===<br />
<br />
The mechanical EndStop gets connected to J5 on the PCB. The Pinout of J5 is (from left to right): GND, DATA, 5V.<br />
(Note that some commercial EndStops may have a different pinout ! You then have to reconfigure the DuPont-connector.)<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="EndStop"><br />

</gallery><br />
<br />
<br />
<br />
<br />
<br />
=== Capacitance-Sensor-Probe ===<br />
<br />
The SensorHead-Probe gets connected with a coaxial cable with BNC-connector, where the Sensing-Ring is connected to the inner wire. You can get an impression on how the probe is made from the video at [https://www.youtube.com/watch?v=XWiALcJwFw8].<br />
<br />
<br />
For getting reasonable signal quality, its important to connect the metal-plate (your workpiece) and also the metal-parts of the test-rig with the SHIELD-ground from the sensor-probe. This is the internal shield-pin of the AD7747 and this is NOT (!!!) identical with the overall GND of the pcb. Therefore it is connected seperately. (Note: In a possible next generation/iteration of the pcb there should become definitely an extra screw-terminal connector with about 3 or 4 SHIELD-ground pins implemented.)<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring Sensor-Probe"><br />
Os_THC02_wiring_sensor.png | SHIELD-ground can be obtained from the wire mesh shield or from the outer metal-parts of the BNC connector.<br />

The arduino firmware is kept as small and simple as possible and should therefore be easily adoptable to daily needs - whatever may turnout to be useful in the future practical work with the torchtable. But from here and as a starting point the programm-logic suggest a workflow, that is based on two modi: <br />
<br />
- the manual mode (where the height can be steered manually by turning a jog-wheel)<br />
<br />
- the "auto-balancing" mode (meaning: automatical height-adaption based on capacitance-sensing data)<br />
<br />
See testing-video on youtube [https://www.youtube.com/watch?v=ggtvRYIhge4&t=7s].<br />
<br />
<br />
<br />
<br />
=== Calibration ===<br />
<br />
When the program starts, there is an initiation phase used for the individual calibration of each run, like:<br />
<br />
- do a homing and therefore get your zero-position (using a mechanical endstop)<br />
<br />
- step upwards to a distance of 30mm and get your maximum height position (by counting steps) and measure the according capacitance value.<br />
<br />
- adjust the working-height automatically by counting steps to a default value (lets say 15mm)<br />
<br />
=== Manual mode ===<br />
<br />
Then the Mainloop starts, in the manual mode. Height is not changed, unless you turn the wheel. If you do so, you can re-adjust the working height to a new level, higher or deeper.<br />
<br />
<br />
If you press the Jogwheel down (like a button) you generally switch between the both modes. If you are currently in the manual mode, you will enter the auto-balancing mode (and vice versa).<br />
<br />
<br />
=== Autobalancing-mode ===<br />
<br />
The autobalancing runs in a loop (until the jogwheel will be pressed again):<br />
<br />
- measure capacitance data<br />
<br />
- calculate the deviation from the wanted working height<br />
<br />
- initiate a number of (motor-)steps to produce a correction-move<br />
<br />
<br />
<br />
=== Filters ===<br />
<br />
There are several places in the sourcecode, where filters and algorithms can be applied, either to achieve a better signal-quality, or influence the "behavior" of the overall-workflow, e.g. like the sensivity. You can define a certain range (e.g. plus or minus 2 aF) in which you consider an deviations as artifcats and dont react with a move. Otherwise you would never have a calm position but instead a jitter of doing permanently correction moves, even if the height of the underlying workpiece doesnt have changed. More about this on the discussion page [http://opensourceecology.org/wiki/Talk:CNC_Torch_Table_Z_Height_Control#Specific_Steps_for_Signal_Improving].<br />
<br />
<br />
<br />
=== Communication ===<br />
<br />
Serial output by USB-cable. This can be used for debugging while development, or in normal use transmit current capacitance-data to a host-monitoring programm on your desktop PC, that samples and visualizes graphically the height-levels of the run.<br />
<br />
It is also planned to communicate to a direct user interface (OLED keypad) by (software) I2C.<br />

*Maybe remove the need for a 5V charger? Can the whole circuit run on 12V? (<-- nope. The Atmel Atmega328 cpu needs 1.8 to 5V, see specs at [http://www.microchip.com/wwwproducts/en/ATmega328]. If you would feed the Nano with 12V you would only burn more energy on the 78M05 voltage regulator onboard.)<br />

= Manual adjustable version of CNC Torch Table Height Controller =<br />
<br />
This is a simple POC-version that allows a manual adjustment of the Z height by turning a jog wheel (see demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]). The wheel can be 3d-printed [https://www.thingiverse.com/thing:17404] and is connected to a rotary encoder of type KY-040.<br />

<br />
<br />
==Design Rationale==<br />
<br />
With this rig it should be possible to manually operate the torch table height by following its slowly moving and regulate the height personally. This can be useful even if in the full version there is a capacitive sensor doing automatically that task, but one may use it then for setting the starting height or use it in other applications where a frequent manual control is an appreciated option.<br />
<br />
The rotary encoder gives up to 20 pulses per revolution to an Arduino-Mega, which translates it into a number of motor steps and triggers these by a TB6600-based stepper-driver. A RAMPS 1.4 may act as a connection layer on top of the Arduino, but can also be omitted. We will show here which pins to wire on the Arduino and on the Ramps as well.<br />
<br />
The firmware consist only of a few lines of Arduino-code, which makes it easy to extend and modify.<br />

== Wiring ==<br />
<br />
There are 3 kind of connections:<br />
<br />
- Power-supply to Ramps/Arduino<br />
<br />
- Rotary Encoder to Ramps/Arduino<br />
<br />
- TB6600 to Ramps/Arduino<br />

</gallery><br />
<br />
<br />
<br />
<br />
=== Power-supply to Ramps/Arduino ===<br />
<br />
1. Ramps: Connect a 12V/5A-Line to the MSTBA4-Port an the Ramps, by using a phoenix-contact plug. This will provide power for Motor as well as board-power for the Arduino-Mega.<br />
<br />
2. Arduino standalone: The Arduino musst be supplied with 5V to 12V. This can be done by the USB-connection to a desktop-pc or by a standard wall-wart ac/dc-adaptor (5V, 2A) for the Mega.<br />
<br />
<br />
<br />
=== RotaryEncoder to Ramps/Arduino ===<br />
<br />
The KY-040 RotaryEncoder has 5 Lines: GND, +5V, SW, DT, CLK. Connect these either to the AUX2 port of the Ramps, or directly to the corresponding digital I/O ports on the Arduino-Mega. <br />
<br />
GND --> GND<br />
<br />
5V --> 5V<br />
<br />
SW --> D44<br />
<br />
DT --> D42<br />
<br />
CLK --> D40<br />

</gallery><br />
<br />
=== TB6600 to Ramps/Arduino, Motor and Power ===<br />
<br />
The TB6600 stepper driverhas three phoenix contact like connectors, <br />
<br />
- one 6-pin to the Ramps<br />
<br />
- one 4-pin to the motor<br />
<br />
- one 2 pin to power-supply<br />
<br />
<br />

</gallery><br />
<br />
<br />
<br />
'''The 6-pin connector''' has the lines ENA-, ENA+, DIR-, DIR+, PUL-, PUL+.<br />
<br />
Make a bridge between ENA- and DIR-, together with a second bridge from DIR- to PUL-. The PUL- contains a second cable which goes towards GND on the Ramps Extruder E0 port. So in total there are 4 wires going either to the Ramps or directly to the Arduino-Mega:<br />
<br />
1. Ramps:<br />
<br />
ENA+ --> EN<br />
<br />
DIR+ --> DIR<br />
<br />
PUL+ --> STEP<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />
2. Arduino-Mega:<br />
<br />
ENA+ --> D24<br />
<br />
DIR+ --> D28<br />
<br />
PUL+ --> D26<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />

</gallery><br />
<br />
<br />
<br />
<br />
'''The 4-pin connector''' has the lines A+, A-, B+, B-.<br />
<br />
In the case of a bipolar stepper motor with 4 wires two of them are the ends of one coil. Connect them like this:<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2"><br />

<br />
<br />
An example for a tested Nema17-stepper with 2A and 59Ncm holding torque is the 17HS19-2004S, see [http://www.omc-stepperonline.com/download/pdf/17HS19-2004S1.pdf], [http://www.omc-stepperonline.com/3d-printer-nema-17-stepper-motor-59ncm84ozin-2a-17hs192004s-p-18.html].<br />
<br />
<br />
<br />
<br />
<br />
'''The 2-pin connector''' has the lines 12V+, 12V-.<br />
<br />
Connect these to a power-supply which can deliver at least 5A. The TB6600 stepper driver is rated for up to 4A and 9-36V DC. That means you can instead of 12V also connect 24V or more towards it.<br />

= Automatic capacitive sensing version of CNC Torch Table Height Controller =<br />
<br />
This is the automatic height levelling version based on the new TorchHeightCTRL_V.02 pcb. (All Sources on GitHub: [[https://github.com/case06/TorchHeightCTRL]])<br />
<br />
<br />
== Design rationale ==<br />
<br />
The new pcb is an all-in-one board, that adds some peripheral interfaces to the application, like for endstop or a future direct user interface (Display).<br />
<br />
In the automated version the 0mm-distance / start-position should be found automatically by homing. <br />
From this it will take a sample and then goes to 30mm height and take another sample for calibration. Then it will go into a loop and trying to balance the distance around a pre-set default-value of 15mm. But if you then push the button of the jogwheel you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />

<br />
<br />
The steppermotor pins on the TB6600 are labeled as B-, B+, A-, A+. I found, that at least for my motor the order must be B-, B+, A+, A-. Otherwise the motor is doing funny things. This may be different on other motors, but you can simply try it by exchanging A+ with A- or B+ with B -. See also the motor diagramm on [http://opensourceecology.org/wiki/File:Os_manthc_stepper_wiring1.png].<br />

The Rotary Eccoder pins GND, 5V, DT and CLK get connected with J7 on the pcb. If you turn the pcb that you can read the labl "J7 Jog" in the right orientation the pins on J7 are (from left to right): 5V, GND, DT, CLK.<br />
<br />
There is one more pin on the KY-040, labelled as "SW". This is a button-press-funktion. Unfortunately the pcb-design was initially intended for another type of rotary encoder, which had not this function, so its not incorporated in the original design. But there is however a workaround (without soldering) for now. The SW pin must be connected to one pin of the ICSP-port on top of the Arduino Nano. (Note: This pin is also part of the UEXT-port, which is not used now. But later we should replace it with another free pin, e.g. pin D9.)<br />

<br />
<br />
<br />
=== EndStop ===<br />
<br />
The mechanical EndStop gets connected to J5 on the PCB. The Pinout of J5 is (from left to right): GND, DATA, 5V.<br />
(Note that some commercial EndStops may have a different pinout ! You then have to reconfigure the DuPont-connector.)<br />
<br />

<br />
<br />
<br />
=== Capacitance-Sensor-Probe ===<br />
<br />
The SensorHead-Probe gets connected with a coaxial cable with BNC-connector, where the Sensing-Ring is connected to the inner wire. You can get an impression on how the probe is made from the video at [https://www.youtube.com/watch?v=XWiALcJwFw8].<br />
<br />
<br />
For getting reasonable signal quality, its important to connect the metal-plate (your workpiece) and also the metal-parts of the test-rig with the SHIELD-ground from the sensor-probe. This is the internal shield-pin of the AD7747 and this is NOT (!!!) identical with the overall GND of the pcb. Therefore it is connected seperately. (Note: In a possible next generation/iteration of the pcb there should become definitely an extra screw-terminal connector with about 3 or 4 SHIELD-ground pins implemented.)<br />
<br />
<br />

<br />
== Firmware ==<br />
<br />
<br />
=== Switching modes ===<br />
<br />
The arduino firmware is kept as small and simple as possible and should therefore be easily adoptable to daily needs - whatever may turnout to be useful in the future practical work with the torchtable. But from here and as a starting point the programm-logic suggest a workflow, that is based on two modi: <br />
<br />
- the manual mode (where the height can be steered manually by turning a jog-wheel)<br />
<br />
- the "auto-balancing" mode (meaning: automatical height-adaption based on capacitance-sensing data)<br />
<br />
See testing-video on youtube [https://www.youtube.com/watch?v=ggtvRYIhge4&t=7s].<br />
<br />
<br />
<br />
<br />
=== Calibration ===<br />
<br />
When the program starts, there is an initiation phase used for the individual calibration of each run, like:<br />
<br />
- do a homing and therefore get your zero-position (using a mechanical endstop)<br />
<br />
- step upwards to a distance of 30mm and get your maximum height position (by counting steps) and measure the according capacitance value.<br />
<br />
- adjust the working-height automatically by counting steps to a default value (lets say 15mm)<br />
<br />
=== Manual mode ===<br />
<br />
Then the Mainloop starts, in the manual mode. Height is not changed, unless you turn the wheel. If you do so, you can re-adjust the working height to a new level, higher or deeper.<br />
<br />
<br />
If you press the Jogwheel down (like a button) you generally switch between the both modes. If you are currently in the manual mode, you will enter the auto-balancing mode (and vice versa).<br />
<br />
<br />
=== Autobalancing-mode ===<br />
<br />
The autobalancing runs in a loop (until the jogwheel will be pressed again):<br />
<br />
- measure capacitance data<br />
<br />
- calculate the deviation from the wanted working height<br />
<br />
- initiate a number of (motor-)steps to produce a correction-move<br />
<br />
<br />
<br />
=== Filters ===<br />
<br />
There are several places in the sourcecode, where filters and algorithms can be applied, either to achieve a better signal-quality, or influence the "behavior" of the overall-workflow, e.g. like the sensivity. You can define a certain range (e.g. plus or minus 2 aF) in which you consider an deviations as artifcats and dont react with a move. Otherwise you would never have a calm position but instead a jitter of doing permanently correction moves, even if the height of the underlying workpiece doesnt have changed. More about this on the discussion page [http://opensourceecology.org/wiki/Talk:CNC_Torch_Table_Z_Height_Control#Specific_Steps_for_Signal_Improving].<br />
<br />
<br />
<br />
=== Communication ===<br />
<br />
Serial output by USB-cable. This can be used for debugging while development, or in normal use transmit current capacitance-data to a host-monitoring programm on your desktop PC, that samples and visualizes graphically the height-levels of the run.<br />
<br />
It is also planned to communicate to a direct user interface (OLED keypad) by (software) I2C.<br />
<br />

*Maybe remove the need for a 5V charger? Can the whole circuit run on 12V? (<-- nope. The Atmel Atmega328 cpu needs 1.8 to 5V, see specs at [http://www.microchip.com/wwwproducts/en/ATmega328]. If you would feed the Nano with 12V you would only burn more energy on the 78M05 voltage regulator onboard.)<br />

= Manual adjustable version of CNC Torch Table Height Controller =<br />
<br />
This is a simple POC-version that allows a manual adjustment of the Z height by turning a jog wheel (see demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]). The wheel can be 3d-printed [https://www.thingiverse.com/thing:17404] and is connected to a rotary encoder of type KY-040.<br />

<br />
<br />
<br />
==Design Rationale==<br />
<br />
With this rig it should be possible to manually operate the torch table height by following its slowly moving and regulate the height personally. This can be useful even if in the full version there is a capacitive sensor doing automatically that task, but one may use it then for setting the starting height or use it in other applications where a frequent manual control is an appreciated option.<br />
<br />
The rotary encoder gives up to 20 pulses per revolution to an Arduino-Mega, which translates it into a number of motor steps and triggers these by a TB6600-based stepper-driver. A RAMPS 1.4 may act as a connection layer on top of the Arduino, but can also be omitted. We will show here which pins to wire on the Arduino and on the Ramps as well.<br />
<br />
The firmware consist only of a few lines of Arduino-code, which makes it easy to extend and modify.<br />

== Wiring ==<br />
<br />
There are 3 kind of connections:<br />
<br />
- Power-supply to Ramps/Arduino<br />
<br />
- Rotary Encoder to Ramps/Arduino<br />
<br />
- TB6600 to Ramps/Arduino<br />

</gallery><br />
<br />
<br />
<br />
<br />
=== Power-supply to Ramps/Arduino ===<br />
<br />
1. Ramps: Connect a 12V/5A-Line to the MSTBA4-Port an the Ramps, by using a phoenix-contact plug. This will provide power for Motor as well as board-power for the Arduino-Mega.<br />
<br />
2. Arduino standalone: The Arduino musst be supplied with 5V to 12V. This can be done by the USB-connection to a desktop-pc or by a standard wall-wart ac/dc-adaptor (5V, 2A) for the Mega.<br />
<br />
<br />
<br />
=== RotaryEncoder to Ramps/Arduino ===<br />
<br />
The KY-040 RotaryEncoder has 5 Lines: GND, +5V, SW, DT, CLK. Connect these either to the AUX2 port of the Ramps, or directly to the corresponding digital I/O ports on the Arduino-Mega. <br />
<br />
GND --> GND<br />
<br />
5V --> 5V<br />
<br />
SW --> D44<br />
<br />
DT --> D42<br />
<br />
CLK --> D40<br />
<br />

</gallery><br />
<br />
=== TB6600 to Ramps/Arduino, Motor and Power ===<br />
<br />
The TB6600 stepper driverhas three phoenix contact like connectors, <br />
<br />
- one 6-pin to the Ramps<br />
<br />
- one 4-pin to the motor<br />
<br />
- one 2 pin to power-supply<br />
<br />
<br />

</gallery><br />
<br />
<br />
<br />
'''The 6-pin connector''' has the lines ENA-, ENA+, DIR-, DIR+, PUL-, PUL+.<br />
<br />
Make a bridge between ENA- and DIR-, together with a second bridge from DIR- to PUL-. The PUL- contains a second cable which goes towards GND on the Ramps Extruder E0 port. So in total there are 4 wires going either to the Ramps or directly to the Arduino-Mega:<br />
<br />
1. Ramps:<br />
<br />
ENA+ --> EN<br />
<br />
DIR+ --> DIR<br />
<br />
PUL+ --> STEP<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />
2. Arduino-Mega:<br />
<br />
ENA+ --> D24<br />
<br />
DIR+ --> D28<br />
<br />
PUL+ --> D26<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2"><br />

</gallery><br />
<br />
<br />
<br />
<br />
'''The 4-pin connector''' has the lines A+, A-, B+, B-.<br />
<br />
In the case of a bipolar stepper motor with 4 wires two of them are the ends of one coil. Connect them like this:<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2"><br />
Os_manthc_stepper_wiring1.png | <br />
</gallery><br />
<br />
<br />
An example for a tested Nema17-stepper with 2A and 59Ncm holding torque is the 17HS19-2004S, see [http://www.omc-stepperonline.com/download/pdf/17HS19-2004S1.pdf], [http://www.omc-stepperonline.com/3d-printer-nema-17-stepper-motor-59ncm84ozin-2a-17hs192004s-p-18.html].<br />
<br />
<br />
<br />
<br />
<br />
'''The 2-pin connector''' has the lines 12V+, 12V-.<br />
<br />
Connect these to a power-supply which can deliver at least 5A. The TB6600 stepper driver is rated for up to 4A and 9-36V DC. That means you can instead of 12V also connect 24V or more towards it.<br />

= Automatic capacitive sensing version of CNC Torch Table Height Controller =<br />
<br />
This is the automatic height levelling version based on the new TorchHeightCTRL_V.02 pcb. (All Sources on GitHub: [[https://github.com/case06/TorchHeightCTRL]])<br />
<br />
<br />
== Design rationale ==<br />
<br />
The new pcb is an all-in-one board, that adds some peripheral interfaces to the application, like for endstop or a future direct user interface (Display).<br />
<br />
In the automated version the 0mm-distance / start-position should be found automatically by homing. <br />
From this it will take a sample and then goes to 30mm height and take another sample for calibration. Then it will go into a loop and trying to balance the distance around a pre-set default-value of 15mm. But if you then push the button of the jogwheel you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />

== Wiring Schema ==<br />
<br />
<br />
[[File:Os_THC02_wiringb.png|1024px]]<br />
<br />
<br />
=== Power Supply ===<br />
'''Warning: The phoenix-contact powersupply connector has NOT the same configuration than the connector of the same type on RAMPS-boards !!!'''<br />
<br />
Dont use the plug of a powersupply that was previously configured for use with a RAMPS-board and has 2 x 12V. The TorchHeightCTRL_V02 board has 1 x 5V and 1 x 12V and will be blown immedately if you give 12V to the 5V line !!!<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring PowerSupply"><br />
Os_THC02_wiring_ps5v.png | Connect 5V (red) and GND (black) from a PC-powersupply to the Phoenix Contact connector on the pcb as shown in the picture. Its a 4-pole connector, but leave two pins not connected (these are normally for 12V but its better to connect the TB6600 directly with the 12V)<br />
Os_THC02_wiring_ps12v.png | Use another string from the Powersupply and connect a 12V line directly with the TB6600, with 12V (yellow) to VCC and GND (black) to GND)<br />
</gallery><br />
<br />
<br />
=== TB6600 ===<br />
<br />
The TB6600 gets connected to J3 on the TorchHeightCTRL_V.02 pcb.<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring TB6600"><br />
Os_THC02_wiring_j3.png | Connections from J3 to the TB6600: EN (blue) goes to ENA+(+5V), DIR (yellow) to DIR+(+5V), STEP (green) to PUL+(+5V) and one of the GNDs (orange; third pin from left to right on J3) to PUL-(PUL). <br />
Os_THC02_wiring_tb6600.png | It doesnt matter, which GND-pin you use, but make sure that on TB6600-side the remaining GND-pins are bridged/connected with the GND-pin that connects to J3. Here the pin ENA-(ENA) is bridged to DIR-(DIR) and then a second bridge goes from DIR-(DIR) to PUL-(PUL), which contains also the (orange) wire that connects to one GND on J3.<br />
Os_THC02_tb6600_switches.png | The switches-setup in a configuration for 1/8 microstepping with a 2.0 Ampere steppermotor<br />
</gallery><br />
<br />
<br />
The steppermotor pins on the TB6600 are labeled as B-, B+, A-, A+. I found, that at least for my motor the order must be B-, B+, A+, A-. Otherwise the motor is doing funny things. This may be different on other motors, but you can simply try it by exchanging A+ with A- or B+ with B -. See also the motor diagramm on [http://opensourceecology.org/wiki/File:Os_manthc_stepper_wiring1.png].<br />
<br />
The power lines should be connected directly with a 12V line of the powersuplly, as mentioned above.<br />
<br />
=== Rotary Encoder KY-040 ===<br />
<br />
The Rotary Eccoder pins GND, 5V, DT and CLK get connected with J7 on the pcb. If you turn the pcb that you can read the labl "J7 Jog" in the right orientation the pins on J7 are (from left to right): 5V, GND, DT, CLK.<br />
<br />
There is one more pin on the KY-040, labelled as "SW". This is a button-press-funktion. Unfortunately the pcb-design was initially intended for another type of rotary encoder, which had not this function, so its not incorporated in the original design. But there is however a workaround (without soldering) for now. The SW pin must be connected to one pin of the ICSP-port on top of the Arduino Nano. (Note: This pin is also part of the UEXT-port, which is not used now. But later we should replace it with another free pin, e.g. pin D9.)<br />
<br />

</gallery><br />
<br />
<br />
<br />
=== EndStop ===<br />
<br />
The mechanical EndStop gets connected to J5 on the PCB. The Pinout of J5 is (from left to right): GND, DATA, 5V.<br />
(Note that some commercial EndStops may have a different pinout ! You then have to reconfigure the DuPont-connector.)<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="EndStop"><br />

</gallery><br />
<br />
<br />
<br />
<br />
<br />
=== Capacitance-Sensor-Probe ===<br />
<br />
The SensorHead-Probe gets connected with a coaxial cable with BNC-connector, where the Sensing-Ring is connected to the inner wire. You can get an impression on how the probe is made from the video at [https://www.youtube.com/watch?v=XWiALcJwFw8].<br />
<br />
<br />
For getting reasonable signal quality, its important to connect the metal-plate (your workpiece) and also the metal-parts of the test-rig with the SHIELD-ground from the sensor-probe. This is the internal shield-pin of the AD7747 and this is NOT (!!!) identical with the overall GND of the pcb. Therefore it is connected seperately. (Note: In a possible next generation/iteration of the pcb there should become definitely an extra screw-terminal connector with about 3 or 4 SHIELD-ground pins implemented.)<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring Sensor-Probe"><br />
Os_THC02_wiring_sensor.png | SHIELD-ground can be obtained from the wire mesh shield or from the outer metal-parts of the BNC connector.<br />

<br />
== Firmware ==<br />
<br />
<br />
=== Switching modes ===<br />
<br />
The arduino firmware is kept as small and simple as possible and should therefore be easily adoptable to daily needs - whatever may turnout to be useful in the future practical work with the torchtable. But from here and as a starting point the programm-logic suggest a workflow, that is based on two modi: <br />
<br />
- the manual mode (where the height can be steered manually by turning a jog-wheel)<br />
<br />
- the "auto-balancing" mode (meaning: automatical height-adaption based on capacitance-sensing data)<br />
<br />
See testing-video on youtube [https://www.youtube.com/watch?v=ggtvRYIhge4&t=7s].<br />
<br />
<br />
<br />
<br />
=== Calibration ===<br />
<br />
When the program starts, there is an initiation phase used for the individual calibration of each run, like:<br />
<br />
- do a homing and therefore get your zero-position (using a mechanical endstop)<br />
<br />
- step upwards to a distance of 30mm and get your maximum height position (by counting steps) and measure the according capacitance value.<br />
<br />
- adjust the working-height automatically by counting steps to a default value (lets say 15mm)<br />
<br />
=== Manual mode ===<br />
<br />
Then the Mainloop starts, in the manual mode. Height is not changed, unless you turn the wheel. If you do so, you can re-adjust the working height to a new level, higher or deeper.<br />
<br />
<br />
If you press the Jogwheel down (like a button) you generally switch between the both modes. If you are currently in the manual mode, you will enter the auto-balancing mode (and vice versa).<br />
<br />
<br />
=== Autobalancing-mode ===<br />
<br />
The autobalancing runs in a loop (until the jogwheel will be pressed again):<br />
<br />
- measure capacitance data<br />
<br />
- calculate the deviation from the wanted working height<br />
<br />
- initiate a number of (motor-)steps to produce a correction-move<br />
<br />
<br />
<br />
=== Filters ===<br />
<br />
There are several places in the sourcecode, where filters and algorithms can be applied, either to achieve a better signal-quality, or influence the "behavior" of the overall-workflow, e.g. like the sensivity. You can define a certain range (e.g. plus or minus 2 aF) in which you consider an deviations as artifcats and dont react with a move. Otherwise you would never have a calm position but instead a jitter of doing permanently correction moves, even if the height of the underlying workpiece doesnt have changed. More about this on the discussion page [http://opensourceecology.org/wiki/Talk:CNC_Torch_Table_Z_Height_Control#Specific_Steps_for_Signal_Improving].<br />
<br />
<br />
<br />
=== Communication ===<br />
<br />
Serial output by USB-cable. This can be used for debugging while development, or in normal use transmit current capacitance-data to a host-monitoring programm on your desktop PC, that samples and visualizes graphically the height-levels of the run.<br />
<br />
It is also planned to communicate to a direct user interface (OLED keypad) by (software) I2C.<br />

*Maybe remove the need for a 5V charger? Can the whole circuit run on 12V? (<-- nope. The Atmel Atmega328 cpu needs 1.8 to 5V, see specs at [http://www.microchip.com/wwwproducts/en/ATmega328]. If you would feed the Nano with 12V you would only burn more energy on the 78M05 voltage regulator onboard.)<br />

= Manual adjustable version of CNC Torch Table Height Controller =<br />
<br />
This is a simple POC-version that allows a manual adjustment of the Z height by turning a jog wheel (see demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]). The wheel can be 3d-printed [https://www.thingiverse.com/thing:17404] and is connected to a rotary encoder of type KY-040.<br />

<br />
<br />
<br />
==Design Rationale==<br />
<br />
With this rig it should be possible to manually operate the torch table height by following its slowly moving and regulate the height personally. This can be useful even if in the full version there is a capacitive sensor doing automatically that task, but one may use it then for setting the starting height or use it in other applications where a frequent manual control is an appreciated option.<br />
<br />
The rotary encoder gives up to 20 pulses per revolution to an Arduino-Mega, which translates it into a number of motor steps and triggers these by a TB6600-based stepper-driver. A RAMPS 1.4 may act as a connection layer on top of the Arduino, but can also be omitted. We will show here which pins to wire on the Arduino and on the Ramps as well.<br />
<br />
The firmware consist only of a few lines of Arduino-code, which makes it easy to extend and modify.<br />

<br />
<br />
<br />
<br />
=== Power-supply to Ramps/Arduino ===<br />
<br />
1. Ramps: Connect a 12V/5A-Line to the MSTBA4-Port an the Ramps, by using a phoenix-contact plug. This will provide power for Motor as well as board-power for the Arduino-Mega.<br />
<br />
2. Arduino standalone: The Arduino musst be supplied with 5V to 12V. This can be done by the USB-connection to a desktop-pc or by a standard wall-wart ac/dc-adaptor (5V, 2A) for the Mega.<br />
<br />
<br />
<br />
=== RotaryEncoder to Ramps/Arduino ===<br />
<br />
The KY-040 RotaryEncoder has 5 Lines: GND, +5V, SW, DT, CLK. Connect these either to the AUX2 port of the Ramps, or directly to the corresponding digital I/O ports on the Arduino-Mega. <br />
<br />
GND --> GND<br />
<br />
5V --> 5V<br />
<br />
SW --> D44<br />
<br />
DT --> D42<br />
<br />
CLK --> D40<br />
<br />

<br />
=== TB6600 to Ramps/Arduino, Motor and Power ===<br />
<br />
The TB6600 stepper driverhas three phoenix contact like connectors, <br />
<br />
- one 6-pin to the Ramps<br />
<br />
- one 4-pin to the motor<br />
<br />
- one 2 pin to power-supply<br />
<br />
<br />

</gallery><br />
<br />
<br />
<br />
'''The 6-pin connector''' has the lines ENA-, ENA+, DIR-, DIR+, PUL-, PUL+.<br />
<br />
Make a bridge between ENA- and DIR-, together with a second bridge from DIR- to PUL-. The PUL- contains a second cable which goes towards GND on the Ramps Extruder E0 port. So in total there are 4 wires going either to the Ramps or directly to the Arduino-Mega:<br />
<br />
1. Ramps:<br />
<br />
ENA+ --> EN<br />
<br />
DIR+ --> DIR<br />
<br />
PUL+ --> STEP<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />
2. Arduino-Mega:<br />
<br />
ENA+ --> D24<br />
<br />
DIR+ --> D28<br />
<br />
PUL+ --> D26<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2"><br />

</gallery><br />
<br />
<br />
<br />
<br />
'''The 4-pin connector''' has the lines A+, A-, B+, B-.<br />
<br />
In the case of a bipolar stepper motor with 4 wires two of them are the ends of one coil. Connect them like this:<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2"><br />
Os_manthc_stepper_wiring1.png | <br />
</gallery><br />
<br />
<br />
An example for a tested Nema17-stepper with 2A and 59Ncm holding torque is the 17HS19-2004S, see [http://www.omc-stepperonline.com/download/pdf/17HS19-2004S1.pdf], [http://www.omc-stepperonline.com/3d-printer-nema-17-stepper-motor-59ncm84ozin-2a-17hs192004s-p-18.html].<br />
<br />
<br />
<br />
<br />
<br />
'''The 2-pin connector''' has the lines 12V+, 12V-.<br />
<br />
Connect these to a power-supply which can deliver at least 5A. The TB6600 stepper driver is rated for up to 4A and 9-36V DC. That means you can instead of 12V also connect 24V or more towards it.<br />

= Automatic capacitive sensing version of CNC Torch Table Height Controller =<br />
<br />
This is the automatic height levelling version based on the new TorchHeightCTRL_V.02 pcb. (All Sources on GitHub: [[https://github.com/case06/TorchHeightCTRL]])<br />
<br />
<br />
== Design rationale ==<br />
<br />
The new pcb is an all-in-one board, that adds some peripheral interfaces to the application, like for endstop or a future direct user interface (Display).<br />
<br />
In the automated version the 0mm-distance / start-position should be found automatically by homing. <br />
From this it will take a sample and then goes to 30mm height and take another sample for calibration. Then it will go into a loop and trying to balance the distance around a pre-set default-value of 15mm. But if you then push the button of the jogwheel you switch from autobalancing- into manual-mode and change this 15mm-default-value by turning the jogwheel. Pushing again switches back into autobalancing mode.<br />

== Wiring Schema ==<br />
<br />
<br />
[[File:Os_THC02_wiringb.png|1024px]]<br />
<br />
<br />
=== Power Supply ===<br />
'''Warning: The phoenix-contact powersupply connector has NOT the same configuration than the connector of the same type on RAMPS-boards !!!'''<br />
<br />
Dont use the plug of a powersupply that was previously configured for use with a RAMPS-board and has 2 x 12V. The TorchHeightCTRL_V02 board has 1 x 5V and 1 x 12V and will be blown immedately if you give 12V to the 5V line !!!<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring PowerSupply"><br />
Os_THC02_wiring_ps5v.png | Connect 5V (red) and GND (black) from a PC-powersupply to the Phoenix Contact connector on the pcb as shown in the picture. Its a 4-pole connector, but leave two pins not connected (these are normally for 12V but its better to connect the TB6600 directly with the 12V)<br />
Os_THC02_wiring_ps12v.png | Use another string from the Powersupply and connect a 12V line directly with the TB6600, with 12V (yellow) to VCC and GND (black) to GND)<br />
</gallery><br />
<br />
<br />
=== TB6600 ===<br />
<br />
The TB6600 gets connected to J3 on the TorchHeightCTRL_V.02 pcb.<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring TB6600"><br />
Os_THC02_wiring_j3.png | Connections from J3 to the TB6600: EN (blue) goes to ENA+(+5V), DIR (yellow) to DIR+(+5V), STEP (green) to PUL+(+5V) and one of the GNDs (orange; third pin from left to right on J3) to PUL-(PUL). <br />
Os_THC02_wiring_tb6600.png | It doesnt matter, which GND-pin you use, but make sure that on TB6600-side the remaining GND-pins are bridged/connected with the GND-pin that connects to J3. Here the pin ENA-(ENA) is bridged to DIR-(DIR) and then a second bridge goes from DIR-(DIR) to PUL-(PUL), which contains also the (orange) wire that connects to one GND on J3.<br />
Os_THC02_tb6600_switches.png | The switches-setup in a configuration for 1/8 microstepping with a 2.0 Ampere steppermotor<br />
</gallery><br />
<br />
<br />
The steppermotor pins on the TB6600 are labeled as B-, B+, A-, A+. I found, that at least for my motor the order must be B-, B+, A+, A-. Otherwise the motor is doing funny things. This may be different on other motors, but you can simply try it by exchanging A+ with A- or B+ with B -. See also the motor diagramm on [http://opensourceecology.org/wiki/File:Os_manthc_stepper_wiring1.png].<br />
<br />
The power lines should be connected directly with a 12V line of the powersuplly, as mentioned above.<br />
<br />
=== Rotary Encoder KY-040 ===<br />
<br />
The Rotary Eccoder pins GND, 5V, DT and CLK get connected with J7 on the pcb. If you turn the pcb that you can read the labl "J7 Jog" in the right orientation the pins on J7 are (from left to right): 5V, GND, DT, CLK.<br />
<br />
There is one more pin on the KY-040, labelled as "SW". This is a button-press-funktion. Unfortunately the pcb-design was initially intended for another type of rotary encoder, which had not this function, so its not incorporated in the original design. But there is however a workaround (without soldering) for now. The SW pin must be connected to one pin of the ICSP-port on top of the Arduino Nano. (Note: This pin is also part of the UEXT-port, which is not used now. But later we should replace it with another free pin, e.g. pin D9.)<br />
<br />

Os_THC02_wiring_j7.png | J7, from left to right: 5V, GND, DT, CLK<br />
Os_THC02_wiring_nano.png | See the 6-pole ICSP-port on top of the Arduino Nano. The most right pin in the top row, denoted as "18, PB4, pcint4, MISO", has to be connected with the pin SW on the KY-040<br />
</gallery><br />
<br />
<br />
<br />
=== EndStop ===<br />
<br />
The mechanical EndStop gets connected to J5 on the PCB. The Pinout of J5 is (from left to right): GND, DATA, 5V.<br />
(Note that some commercial EndStops may have a different pinout ! You then have to reconfigure the DuPont-connector.)<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="EndStop"><br />

</gallery><br />
<br />
<br />
<br />
<br />
<br />
=== Capacitance-Sensor-Probe ===<br />
<br />
The SensorHead-Probe gets connected with a coaxial cable with BNC-connector, where the Sensing-Ring is connected to the inner wire. You can get an impression on how the probe is made from the video at [https://www.youtube.com/watch?v=XWiALcJwFw8].<br />
<br />
<br />
For getting reasonable signal quality, its important to connect the metal-plate (your workpiece) and also the metal-parts of the test-rig with the SHIELD-ground from the sensor-probe. This is the internal shield-pin of the AD7747 and this is NOT (!!!) identical with the overall GND of the pcb. Therefore it is connected seperately. (Note: In a possible next generation/iteration of the pcb there should become definitely an extra screw-terminal connector with about 3 or 4 SHIELD-ground pins implemented.)<br />
<br />
<br />
<gallery widths="420" heights="400" perrow="2" caption="Wiring Sensor-Probe"><br />
Os_THC02_wiring_sensor.png | SHIELD-ground can be obtained from the wire mesh shield or from the outer metal-parts of the BNC connector.<br />
</gallery><br />
<br />
== Firmware ==<br />
<br />
<br />
=== Switching modes ===<br />
<br />
The arduino firmware is kept as small and simple as possible and should therefore be easily adoptable to daily needs - whatever may turnout to be useful in the future practical work with the torchtable. But from here and as a starting point the programm-logic suggest a workflow, that is based on two modi: <br />
<br />
- the manual mode (where the height can be steered manually by turning a jog-wheel)<br />
<br />
- the "auto-balancing" mode (meaning: automatical height-adaption based on capacitance-sensing data)<br />
<br />
See testing-video on youtube [https://www.youtube.com/watch?v=ggtvRYIhge4&t=7s].<br />
<br />
<br />
<br />
<br />
=== Calibration ===<br />
<br />
When the program starts, there is an initiation phase used for the individual calibration of each run, like:<br />
<br />
- do a homing and therefore get your zero-position (using a mechanical endstop)<br />
<br />
- step upwards to a distance of 30mm and get your maximum height position (by counting steps) and measure the according capacitance value.<br />
<br />
- adjust the working-height automatically by counting steps to a default value (lets say 15mm)<br />
<br />
=== Manual mode ===<br />
<br />
Then the Mainloop starts, in the manual mode. Height is not changed, unless you turn the wheel. If you do so, you can re-adjust the working height to a new level, higher or deeper.<br />
<br />
<br />
If you press the Jogwheel down (like a button) you generally switch between the both modes. If you are currently in the manual mode, you will enter the auto-balancing mode (and vice versa).<br />
<br />
<br />
=== Autobalancing-mode ===<br />
<br />
The autobalancing runs in a loop (until the jogwheel will be pressed again):<br />
<br />
- measure capacitance data<br />
<br />
- calculate the deviation from the wanted working height<br />
<br />
- initiate a number of (motor-)steps to produce a correction-move<br />
<br />
<br />
<br />
=== Filters ===<br />
<br />
There are several places in the sourcecode, where filters and algorithms can be applied, either to achieve a better signal-quality, or influence the "behavior" of the overall-workflow, e.g. like the sensivity. You can define a certain range (e.g. plus or minus 2 aF) in which you consider an deviations as artifcats and dont react with a move. Otherwise you would never have a calm position but instead a jitter of doing permanently correction moves, even if the height of the underlying workpiece doesnt have changed. More about this on the discussion page [http://opensourceecology.org/wiki/Talk:CNC_Torch_Table_Z_Height_Control#Specific_Steps_for_Signal_Improving].<br />
<br />
<br />
<br />
=== Communication ===<br />
<br />
Serial output by USB-cable. This can be used for debugging while development, or in normal use transmit current capacitance-data to a host-monitoring programm on your desktop PC, that samples and visualizes graphically the height-levels of the run.<br />
<br />
It is also planned to communicate to a direct user interface (OLED keypad) by (software) I2C.<br />

*Maybe remove the need for a 5V charger? Can the whole circuit run on 12V? (<-- nope. The Atmel Atmega328 cpu needs 1.8 to 5V, see specs at [http://www.microchip.com/wwwproducts/en/ATmega328]. If you would feed the Nano with 12V you would only burn more energy on the 78M05 voltage regulator onboard.)<br />

See how to load the pcb sources from Github and into Kicad (using OSE Linux (or others)) on this instructional youtube-video: https://www.youtube.com/watch?v=v-nhG5vuZW0<br />
<br />
The steps are:<br />
<br />
1. Start OSE Linux<br />
2. open a shell and type: cd /tmp<br />
3. There type: git clone https://github.com/case06/TorchHeightCTRL<br />
4. open Kicad and choose from the file menu "open project".<br />
5. in the upcoming mask go to and open /tmp/TorchHeightCTRL/torchctrl.pro<br />
6. in the top icon-bar of the project-window press the most left icon "Schematic editor".<br />
7. Probably a error-msg concerning a "linear.lib" occures, press "ok" and ignore it.<br />
8. In the upcoming scheme-editor window press on the right side of the top icon bar the second last icon "Start pcb-new"<br />
9. In the upcoming pcblayout-editor choose "3D-viewer" from the edit-menu.<br />

= Manual adjustable version of CNC Torch Table Height Controller =<br />
<br />
This is a simple POC-version that allows a manual adjustment of the Z height by turning a jog wheel (see demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]). The wheel can be 3d-printed [https://www.thingiverse.com/thing:17404] and is connected to a rotary encoder of type KY-040.<br />
<br />

<br />
- demonstration video on youtube: [https://www.youtube.com/watch?v=ZJflxWt9qyQ]<br />
<br />
<br />
<br />
==Design Rationale==<br />
<br />
With this rig it should be possible to manually operate the torch table height by following its slowly moving and regulate the height personally. This can be useful even if in the full version there is a capacitive sensor doing automatically that task, but one may use it then for setting the starting height or use it in other applications where a frequent manual control is an appreciated option.<br />
<br />
The rotary encoder gives up to 20 pulses per revolution to an Arduino-Mega, which translates it into a number of motor steps and triggers these by a TB6600-based stepper-driver. A RAMPS 1.4 may act as a connection layer on top of the Arduino, but can also be omitted. We will show here which pins to wire on the Arduino and on the Ramps as well.<br />
<br />
The firmware consist only of a few lines of Arduino-code, which makes it easy to extend and modify.<br />

<br />
<br />
<br />
=== Power-supply to Ramps/Arduino ===<br />
<br />
1. Ramps: Connect a 12V/5A-Line to the MSTBA4-Port an the Ramps, by using a phoenix-contact plug. This will provide power for Motor as well as board-power for the Arduino-Mega.<br />
<br />
2. Arduino standalone: The Arduino musst be supplied with 5V to 12V. This can be done by the USB-connection to a desktop-pc or by a standard wall-wart ac/dc-adaptor (5V, 2A) for the Mega.<br />
<br />
<br />
<br />
=== RotaryEncoder to Ramps/Arduino ===<br />
<br />
The KY-040 RotaryEncoder has 5 Lines: GND, +5V, SW, DT, CLK. Connect these either to the AUX2 port of the Ramps, or directly to the corresponding digital I/O ports on the Arduino-Mega. <br />
<br />
GND --> GND<br />
<br />
5V --> 5V<br />
<br />
SW --> D44<br />
<br />
DT --> D42<br />
<br />
CLK --> D40<br />

<br />
=== TB6600 to Ramps/Arduino, Motor and Power ===<br />
<br />
The TB6600 stepper driverhas three phoenix contact like connectors, <br />
<br />
- one 6-pin to the Ramps<br />
<br />
- one 4-pin to the motor<br />
<br />
- one 2 pin to power-supply<br />
<br />

<br />
<br />
<br />
'''The 6-pin connector''' has the lines ENA-, ENA+, DIR-, DIR+, PUL-, PUL+.<br />
<br />
Make a bridge between ENA- and DIR-, together with a second bridge from DIR- to PUL-. The PUL- contains a second cable which goes towards GND on the Ramps Extruder E0 port. So in total there are 4 wires going either to the Ramps or directly to the Arduino-Mega:<br />
<br />
1. Ramps:<br />
<br />
ENA+ --> EN<br />
<br />
DIR+ --> DIR<br />
<br />
PUL+ --> STEP<br />
<br />
PUL- --> GND<br />
<br />
<br />
<br />
2. Arduino-Mega:<br />
<br />
ENA+ --> D24<br />
<br />
DIR+ --> D28<br />
<br />
PUL+ --> D26<br />
<br />
PUL- --> GND<br />

An example for a tested Nema17-stepper with 2A and 59Ncm holding torque is the 17HS19-2004S, see [http://www.omc-stepperonline.com/download/pdf/17HS19-2004S1.pdf], [http://www.omc-stepperonline.com/3d-printer-nema-17-stepper-motor-59ncm84ozin-2a-17hs192004s-p-18.html].<br />
<br />
<br />
<br />
<br />
<br />
'''The 2-pin connector''' has the lines 12V+, 12V-.<br />
<br />
Connect these to a power-supply which can deliver at least 5A. The TB6600 stepper driver is rated for up to 4A and 9-36V DC. That means you can instead of 12V also connect 24V or more towards it.<br />

<br />
<br />
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />

<br />
I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- today i received an order from a special material filament named "Iglidur I150 Tribo-Filament" from Igus [http://www.igus.de/product/12404]. This is specially suited for 3dprinting sliding parts and is about 50 times less abrasive than ABS.<br />

I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

<br />
I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- today i received an order from a special material filament named "Iglidur I150 Tribo-Filament" from Igus [http://www.igus.de/product/12404]. This is specially suited for 3dprinting sliding parts and is about 50 times less abrasive than ABS.<br />
<br />
I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />
<br />
<br />
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib<br />
<br />
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.<br />
<br />
= '''Thu Aug 31, 2017''' =<br />
<br />
- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources<br />
<br />
<br />
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.<br />
<br />
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.<br />
<br />
Kudos to Christian, who did an excellent job with the OSE-Linux !!!<br />
<br />
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

<br />
I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.<br />
