I have a G0704 CNC Conversion running with Mach3. I just replaced the Grizzly spindle motor with the subject motor. I can get it to run outside of Mach3 with the controller/keypad that comes with it but, for the life of me, I can't get it to run through Mach3. I tried running it under PWM control (with wiring and setup info provided by A.T. tech support) - nothing. I also tried running under step/direction control with wiring/setup info off the A.T. - website - still nothing.
Is there anyone out there who had a similar experience and who might have suggestions? I'm beginning to think that my control board that came with the unit (portions devoted to Mach3 control) might be faulty.

Thanks.
Greg
