Good morning. We have a HAAS ST30 lathe where a Z value in the program was changed from +.002" to +26.1265".... The program ran a month ago and was saved back to the hard drive. Only 2 people run this machine, one of which doesn't have the know how to make a change like that. Thankfully this was a positive value and didn't crash the turret into the chuck. Has anyone had a value like this changed due to a power surge or something like that? We can't figure out how in the hell a value was changed so much.
