I am useing the FET-3 System from Stepper World, The software that comes with it (VB STEPPER) runs the motors nice and smooth all the way up to the programs top speed, as well as slow (Smooth at any speed). Now I use MACH 3 and no matter what I do I can only get semi smooth results at one speed, about 3/4 of the top speed in VB Stepper very slow, slow, med, fast Everything is jumpy Even seems like its skipping steps, at all speeds.
Thanks for any responce
