Hi Joe
Hi All

Below two images of a test of 0.25mm in 0.01mm steps.

The Dial indicator used was a Mitutoyo 0.01mm resolution unit. Ideally I should have used a higher resolution unit. I have one but I would need to make a mounting base for it. This would reduce the Measurement error slightly. Having said that the residuals look pretty reasonable. I guess I am splitting hairs here.
