This is from tonight. The video in the link show going from zero to various distances and back to zero. You can see the gauge is within about half a thousands each time...I'm pleased with that. I'm sure my cheap gauge and my farmer clamping system don't add to the accuracy of this set up. The problem is when any pressure is applied to the gantry the gauge is moving. With small pressure +/-0.005 and with a little bit of force +/- about .015-.02. Ran more 1" squares as well and I see the same issues. Some were off by 0.025 to 0.030 inches. Well almost 1am back to work in a few hours.
