I have a Harrison 1400 S lathe that uses a Fanuc 21iT control.. It has worked fine for about 4 years--now I am having a problem that I previously had with a Romi 17 with same control. We 32 tools set up with z and X info. Up until 2 weeks ago--they had been repeatable. Now sometimes after machine has been down and is started up--the X value for all 32 tools will have shifted between .006 and 0.015 inches.

I haev a friend in Scotland that is having the exact same problem.

Can anyone help?
