We got a 321GLtp a few months ago, but I'm just now getting a chance to play with its tactile capabilities. I think I have the tool calibrations right, but I'm not sure what to expect.

I did a part alignment with a touch probe then measured the same circle and Z point with both the vision and the touch probe.

The diameter measured exactly the same with both methods. For its center point, the X is the same, the Y is .0002 off and the Z is .0125 off.

Is that an expected error on the XY axis?

Can the Z ever be calibrated to be the same or are there too many variables with lighting to make that possible?
