McWire CNC controller wont function properly. Suggestions? Answered
I built a McWire CNC controller and it won't function properly. I measured 19 volts at the A//B terminals when I sent a signal to the circuit via KCAM but I measured a constant 1.5 volts at B-/A- regardless of whether or not I sent a signal to it. I am pretty sure that I wired up the circuit correctly. The motor will "stiffen up" when I jog it with KCAM but it won't rotate. Any help would be appreciated because I am at my wits end with this thing. Thanks in advance!
