Found a ghetto way to check tool offsets without a probe
Started using a piece of cigarette paper between the tool and the part to find Z zero, way cheaper than that 3D taster I broke last week. Just jog down until the paper barely drags then add 0.1mm for the paper thickness, been surprisingly consistent on my Haas. Anyone else got janky but reliable ways to set tools when you're in a pinch?

Yeah you tried the feeler gauge trick with a cigarette paper too? I've done the same thing for years on my old Fadal, works way better than you'd think. Just make sure you're consistent with how much drag you feel, I always shoot for that barely-there resistance.

Man, I tried that cigarette paper trick once and ended up with a shredded mess and a feeler gauge stuck sideways in the ways. Took me 20 minutes to fish it out with a pair of tweezers and a lot of bad language. I still do the drag method too, but I've learned to use the old business card trick instead, just fold it over a couple times for a consistent thickness. You ever mark the folds on the card so you know which thickness you used last time?
