Electronics for 3-axis CNC


All the parts needed to drive the three supplied stepper motors. High performance drivers for high speed operation. Intended to work with Mach3 software (free demo version). Can be run from USB if you don’t have a printer port. I recommend the UC100. It is gray plastic. There is a fake one that is chrome looking with a short cable. I haven’t gotten the one I bought to work.
