Thanks Jonathan,

Reason for the question is I am zeroing by jogging up to the work piece on each side and setting that axis to zero and wanted to jog by 2.5mm afterwards in x/y to take account of my 5mm end mill, but I guess I should be using the tool offset for this.

I have also seen people using lasers (collet mounted and offset mounted) and web cams (with cross hairs) for zeroing and of course the more "pro" ruby tipped probes - any idea who might sell the probes and/or lasers? I have the aspiration to try probe scanning at some point as well, so the latter might suit me more than the laser technique.

Gotta love being on the learning curve.....its half the fun.
