This is on a 1999 Haas VR-11B. This machine has been great but recently we started seeing the tolerances slipping and then out to the point where it wont make good parts. Most of the parts this machine runs are +/- .010. I think I have checked everything. It repeats this same amount every time. All the tool lengths and pivot lengths are correct and I can take this program from this machine and it will make a good part on my other 2 VR's.
