I can't get my motors to startThey are not hotand I think they are wired properly.There may be something in Mach3 that I'm not doing rigjht

I will need to know a bit more about your setup: What controller are you using? What driver are you using? What motor are you using? What wires do you have the motor connected to the driver? Is the driver wired to a power supply? What is the voltage of the power supply? How do you have the controller wired to the driver for step/direction/5v/gnd? What voltage and current is the power supply rated? What is the max voltage is the driver rated?
