Grabbed the wrong tool offset last night and scrapped a $400 part

I was running a late shift at the shop in Cleveland, tired after about 10 hours, and punched in the wrong tool offset on a Haas VF-2. Instead of checking my G10 line I just hit cycle start on a finished aluminum bracket. Heard that awful grinding sound and realized I cut 0.050 inches too deep into the face. Boss wasn't happy but at least we caught it before the next part went through. Anyone else ever zone out and pay for it like that?

That "awful grinding sound" is the worst alarm clock ever invented.

Oh absolutely, @wells.evan, I swear my car makes that same noise just to ruin my morning too.

Ever try sticking a rubber hose in there and giving it a good shake? I had that same problem with my old truck, turned out a pebble got stuck in the brake dust shield. Took me forever to find it because I kept thinking the transmission was going out. Ended up prying it out with a screwdriver and it never came back. Worth a shot before you pay a mechanic to tell you it's nothing.
