I re tuned the drive using DMM Tech's latest software that has autotuning. After this i re tuned in Kmotion and was getting much better results, about .0005" to .0007" of error. Then i done a test feed move at 1IPM of .001" ,the DAC sets at about -40 to -50 after it has moved, its dithering a little, but KMCNC dro does not show any movement. So i tryed another test move of .0005" and measured movement with an indicator is .001"
