This points very strongly to the problem being the backlash compensation. (which won't be active in pncconf). In fact you have a backlash compensation of 0.05 and an f-error of 0.005. So on every reversal you are _automatically_ out of position by 10x your f-error limit. Your step scale of 314 steps per mm means that you have a resolution of 0.003mm, so your f-error is 1 microstep. That's pretty tight, especially for the high-speed f-error. Try 0.015 for min_ferror and 0.1 for f-error and things should run rather better. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.
