Read a post on another forum about a guy who crashed a $40k Haas after fat-fingering a tool offset during a midnight shift

He said he hit the wrong key because the DRO font was too small and he was running on 4 hours of sleep, which makes me wonder how many of us are running machines half-awake with bad interfaces and no backup check, has anyone else nearly scrapped a part from a simple typo?

Had a guy at my last shop who ran a whole pallet of titanium parts with a face mill that was .015 off. He'd set the tool offset, then bumped the handwheel by accident walking past the control. Didn't notice until inspection flagged every single part for thickness. Boss tried to blame the DRO layout but we all knew he just got in a hurry.

But what I really wonder is, how many shops actually have a second set of eyes on critical offsets before you hit the green button? I've seen guys run a whole production shift on a bad tool length because they were too proud to ask someone to double check. Is it just a culture thing where everyone's expected to never make mistakes, or are there actual systems that work?
