pa2262,

Glad to see you took the initiative to look it up and make the change so quickly.

Yup, sounds like the limit switch or something has changed position and hits the limit switch too soon. You might want to check for chips up there. If it changes back there will be another crash!

Also, check that the carousel is not bent. Go to tool 10 or 11 and see if the height is still good. Sometimes they will get bent, especially with older machine where the aluminum is getting corroded and thin.
