I just built a MPCNC and am struggling to learn the software and get the machine to run for testing and later
printing parts. I can’t find an instruction manual or someone that has step by step instructions. Do you have any suggestions on sources for operation and use of the MPCNC? I have the reprap screen set and can operate x y z axis but have not been able to send commands to the Arduino from my PC. Are you doing anything similar? Anyhelp would be appreciated.
