Hello all.. I am running Mach3 with hobbycnc pro board and Kollmorgen JPT55 Stepper motors. I got the motors spinning in motor tuning and jog mode but in both modes, the stepper will not spin in the direction pressed on the controller with any consistency. Anybody had that problem or know what could cause it? Motor wiring? Software setup? Power? When I ran the driver test in Mach3, the timeline is rather short pulses in groups along a straight line. Would this be considered correct?
Any help is greatly appreciated.
