I just bought another J325 and I can't get my axis lag to .0000 +-.0002 so the control won't let me run any G0 in position codes,I've adjusted the servo amps and even swapped servo amps out of my other mill that has .0000 axis lag and it stays the same X.0009 Y.0011 Z.0008 axis lag, I've taken the brushes out of all of the servos and blown all of the dust out I had to do this because I was getting a motor overload fault on the control which was a bad brush spring on the Z axis, I'm getting 104 VDC at the bus capacitor and +&-15 vdc and the servo amps, does anyone have any suggestions as to what to check now?
