Warning: checking tool offsets cost me an entire 10 hour shift

Ngl I thought I was being thorough when I loaded a new job on our HAAS VF-2 last Tuesday. Spent 20 minutes double checking the G54 location and the tool lengths felt right. First part ran fine but the second one gouged the side wall by like .030 inches. I spent the next 9 hours chasing a ghost in the machine. Swapped holders, re-cut tools, even called a buddy who runs a shop across town. Finally around 5pm I realized the tool offset page had a DRO value that was off by exactly the radius of a endmill I used on the previous setup. Just a dumb misclick when I hit the measure button. Has anyone else lost a whole day to something that simple?

Man I read something from a tooling engineer last week who said 90% of setup errors come from something that simple, and I've definitely thrown away a shift chasing my tail over a wrong decimal or a forgotten wear offset before.

Yeah same here @taylorc50, I always blamed it on the machine or the material until I actually paid closer attention to my own inputs... definitely made me slow down and double check now.
