Spent 4 hours chasing a tool offset issue that was just a loose screw...

I was running a part in a HAAS VF-2 last Tuesday and the Z height kept drifting by like .003 every cycle. Spent two whole afternoons re-checking my program, re-setting offsets, even called a buddy for help. Turns out the set screw on the tool holder was just a little loose from a crash 2 months ago. Anybody else ever spend way too long on something that stupid simple?

Bet the crash sent a vibration that slowly walked that screw loose over time.

Whoa, so the crash might've actually tightened something it shouldn't have (kind of backwards, but I see it).

That "slowly walked that screw loose over time" idea is interesting, @brooke_murray, but I wonder if the real story is what didn't get shaken off. What if the crash actually seated something that should have been loose, and that hidden tightness is what caused the whole chain of events later?
