@Zax Excuse me, and ... thanks.
But, I have already tried and they do not respond, they will be very busy with the Chinese New Year ......
And, have you managed to get this CNC to work at some point? What I am doing now is with Arduino Uno, an expansion shield, and through GBRL, to make it finally! the engines start, run, super thin, I just need to build a plate to accommodate a third motor, the one that raises / lowers, and writes.
I have used all the material of EleksDraw, minus the electronic board, and its software.
So, and I repeat, thank you, greetings.
