I am trying to build a nice little CNC, and I want to test my computer to stepper connection. At this point I have Mach 3 installed, I have my 4 axis breakout board hooked up, my stepper drivers hooked up and a stepper motor connected to the driver and it is sitting on the work bench. I wish to confirm my wiring is sound. I have tried the jog control, and there is no action at all! Is there a way to be sure my computer is talking to the outside hardware? I have a windows xp box.
