If the drive is set to 10000 pulses per inch and you are using software step generation then a typical base-thread rate of 30,000nS should let you move at 3 inches per second. Using hardware pulse generation you should be able to increase this, as long as the drive system can cope. I suspect the confusion comes from the subject line referring to counting rather than pulse generation. The Mesa 5i25 looks like a parallel port card and (in the G540 configuration) you wire it like a parallel port card. It isn't a huge problem to make a custom DB25 cable to adapt the pinouts if required. (In other configurations it can be nothing like a parallel port, and you can hook 384 lines of IO to it, or directly connect 16 30A servo drives) ------------------------------------------------------------------------------ For Developers, A Lot Can Happen In A Second.
