We run a Brown & Sharp Global Image 5-7-5 CMM with Pc Dimis control and we're having some very strange accuracy issues in Z. The machine will calibrate perfectly, but when we go to measure something we can't get a consistent value in Z. We've tried cleaning everything we possibly can, and still, when measuring a gauge block it will be anywhere from 0.001-0.004" off which is a little mind blowing. Thinking it might be a bad probe body but wanted to see if anyone else has had a simmilar issue.
