General Mach Discussion / Re: Question about Mach3 Stepper Motor Tuning. Still a few Rough Spots

McFlyman;
Hmmm, tough one, but then again, I'm no stepper guru.
Are you using a passive or active breakout board? I had a problem with a passive board because the pulses put out by the parallel port were whimpy 3 volt pulses, so I bought an amplified board which completely solved the problem. My symptoms were sort of like yours, but maybe not exactly.
I'll keep thinking, but that's about it for the moment. The only other (im)probable error is all 3 motors hooked up improperly. The phases fighter each other, or something.
Let us know if you solve it and what it took to fix it.
Tom.
