I finally realized why my tool offsets kept drifting on the Haas

Had a long talk with a retired machinist named Pete from Toledo last weekend at a swap meet. He pointed out that I was clamping my vice jaws way too tight and flexing the whole setup, which threw my Z axis readings off by .003 every time. Made me think back to my second year running a Mori Seiki where I chased a .005 error for three days before giving up. Anybody else ever had a simple clamping pressure issue mess with their offsets?

I used to think clamping harder was always better until I ran into the exact same thing on a Haas VF2. That .003 drift drove me nuts until I realized I was squeezing the life out of the soft jaws. Pete from Toledo knows his stuff, that's for sure.

Yeah, I learned that one the hard way... crushed a part AND my pride.
