I have contributed a board that was from a 3d MELZI v3 printer that I had in the house. and looking for the codes (finware CORE XY) to upload to the board. once downloaded the code we tried to load the program or finware so that it understands that it is a corexy machine but it did not work because the same board has n short.
We tried to use an arduino as isp to load the new finware but it was never achieved and we chose to use the same milling board that was not functional (mechanically) and it was much easier to use that board since it was an arduino with a shiel cnc
I have connected the motors to Arduino with their CNC shield and power supply. helping a little Matthew in getting the CORE XY code and make the program to make the draw, I could upload the finware and of the microcontroller.
basically we have made a square in illustrator and generate the G code in FabModule to load the machine and draw. part that Peter was responsible for.
