Re: Erratic stepper question.

I would like to thank all of you for your suggestions. Today I put a
friction load to one of my steppers by clamping the shaft with a pair
of pliers lined with a paper towel. When I reran the G-code file
that had been giving me problems, everything worked fine.

Thanks,

Jason
