Sorry what I meant was .0005" between multiple parts The machine did not dither or do the jerking with the old Anilam control.Someone said the axis might be drifting then snap back into position, I put an indicator on an axis and it holds position and when it jerks it moves about .002" out of position then back, hard to tell it so fast.
The servo motor is connected to the ball screw with a timing belt and when it jerks it sounds like the belt was snapped like a rubber band, you can also feel and see it in the belt. see: http://sites.google.com/site/bmklawt/ For all the information on my machine I appreciate everyone's help ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
