I regularly do in-process probing to set x offsets on parts. I usually put the part or parts in the vise or a fixture close to where they need to be, hit the "go" button and the probe touches off on the part to give me an accurate x offset for the rest of the program to run off of.
Today I had two parts in a fixture, one gets the x-axis set in G54 and the other in G55. This has worked for hundreds of parts flawlessly. This time I had a "non-standard" part in my G55 location, so I jogged the probe in place manually for the G55 setting. Instead of letting the program run from the start, I just ran it from where the G55 gets probed. Yup, you guessed it, program failed to pick up the z offset for the probe and proceeded to rapid my probe right into the fixture and vise. The machine z-axis alarmed out after completely shattering the probe, knocking my fixture out of the vise (ruining it), and destroying my parts. Expensive mistake today. Hopefully I didn't knock anything out of alignment on the VF-2, or brinnel the spindle bearings. Ouch! I may have uttered a few choice words.
I'll talk to my insurance guy tomorrow. When I got my insurance originally back in 2008 I had crash coverage. Hopefully I still do.
Learn from my mistake!
