Why does nobody talk about using the machine's own probe to find a vise that's out of square
Last week I was setting up a run of 40 aluminum brackets on the Haas and my first part came out tapered on one side. I checked the vise with a dial indicator and it looked fine, but I bolted it down in a different spot on the table and the same taper showed up. So I stuck the Renishaw probe in the spindle and swept the fixed jaw with it, just running the probe along the face and watching the numbers on the screen. Turned out the whole vise body was twisted about 0.003 over 6 inches and my indicator setup was hiding it because I was only checking one corner. I shimmed the back corner with a piece of .002 shim stock and probed it again until the numbers flattened out. Nobody at my shop ever showed me this, I just got tired of scrapping parts. I know it takes an extra 5 minutes but it beats chasing your tail all day. Has anyone else used the probe for vise setup or do you just trust your indicator?

Man, I always trusted my indicator until I read this and now I'm second guessing everything.
