Yes... what limit do you think is reasonable? Chris

"When I was using the parallel port, the step and hold were 12000 and 3500. The software maxes this out at 10000 for the 7i92 so I used that instead of 12000. X axis will move, but NOT very smoothly. Y and Z do not move at all. All 3 axis are identical, with the exception of the length of the leadscrew (china cnc3040 machine). Same motor, same leadscrew pitch, same wiring, etc. The motor driver is a TB6560 (not great, but works fine for my tinkering)." After advising the chap to edit the ini file and set the step timing where he needed for his drives. "Ok, I finally have 3 axis working smoothly. Editing the ini file and playing with the step and hold times did the trick. My apologies for being a little cranky, but I was working on it all last week and into the weekend and was just hitting the brick wall. I had assumed that the PncConf was showing the true max limits (step/hold) of the card, so I didn't think there was anything else to be done."
