Old timer at the shop told me to never trust the auto tool setter

Guy named Pete who's been running CNCs since the 80s warned me that the automatic tool setter can drift after a while. I figured he was just being paranoid, you know, old school stuff. Last Tuesday I ran 30 parts off without checking and every single one had a 0.015 depth issue because the setter was off by a hair. Now I do a quick manual check before any batch over 10 parts. Anyone else had their tool setter lie to them like that?

He's not wrong but 0.015 is a lot for drift alone.

Yeah I've been there. Switch pads and resurface rotors first. Cheap fix.
