Is there any easy way to tell if the motor is good. When I tried to run them in mach3 they just buzz and can't seem to get the motor tuned?
You will need to include what you are using for motors and drivers. Next would be taking a look at your connections to verify if the motor is wired to step the coils in a TEST MODE. Power supplies. Drag on the slide assembly. Then look into your output pulse data paramters in the software etc. Let the process of elimination lead you from the obvious to the curious. There is a needle there somewhere.
Basically, if it don't work......it aint good, but it may not be the motor. Have you done any other tests to rule out the above?
