Just had this happen today. Running along just fine, 2 hours into the job and then the End Mill snaps with about 5 minutes to go. What I would like to do it is:
1.Pause
2.Stop the spindle
3. Jog to a place where I can change the end mill
4.Touch off again to set my Z
5. Resume the job where it left off (or even better back up a few line of G Code)
