4. Embedded Programming

This week we learned how to create an electronic board from its cutting on the CNC PCB to soldering the components and finally programming the blinking of a LED light.

My journey

This was a new skill to learn and I enjoyed it !

I mostly enjoyed the soldering of the components, even though it wasn't so easy.

The pieces are so small, I've lost one by pinching it to hard with the pliers... (and found it a bit later !)

Individual assignment

My assignement was to build a Quentorres board and make it work by programming the blinking of a LED light

Preparing the board

To get the board cut and engraved, we prepared the G-Code files in Mods.

For that, we saved the Quentorres PNG files that are in the Fabcloud (no need to rename the files).

Discovering Mods

The Mods website is simple to use and has a minimalist interface.

To create the G-Code files, you have to right-click on the interface and choose "G-Code > mill 2D PCB". This will open all the parameters you'll need to configure the Quentorres PCB cutting and engraving.

First we worked on the "traces" file by opening it in the "read png" box.

To create the traces, we had to insert the path parameters in the "path to G-code" box.

  • cut speed :
  • plunge speed :
  • jog height :
  • spindle :
  • dwell :
  • tool :
  • coolant :
  • format :

Then we changed the mill raster parameters in the "mill raster 2D" box.

  • tool diameter :
  • cut depth :
  • max depth :
  • offset number :
  • offset stepover :
  • direction :
  • path merge :
  • path order :
  • sort distance :

After entering all the parameters, clicking on "Calculate" (in the bottom of the "mill raster 2D" box) will open the view of the result. This shows where the tool will engrave.
