Command John is correct! most of the time the backlash IS in the thrust bearings. If you have anything over .0015 of backlash, you can't comp for it, and make your cut perfect, so say the hardcore mold cutters! put an indicator on the end of your ball screw and see if its moving, while you jog back and forth, that will tell you where the bear **** in the buckwheat....MY GOD, i'v been hanging out with old people to much! |
