Lost a full day on a bad tool offset because I trusted the last guy's notes
Picked up a job on a used Haas VF-2 last month and the previous operator left a handwritten setup sheet. Trusted his tool 3 offset was good, ran 40 parts before checking one with a mic. They were all off by 0.012", scrap cost me about $300 in aluminum and 9 hours of rework. Anyone else learn the hard way to verify every offset after a handoff or do you guys just start fresh every time?

even after verifying you gotta recheck after the machine sits overnight or warms up, thermal drift will bite you every time... i touch off every tool at the start of a shift no matter what the notes say.
