I've just jumped on the 3D probe band wagon, spent the evening setting it up and wiring it in, and had a little play with the probing routines in my (slightly older, before the default screenset change) version of UCCNC.

I've managed to figure out the basic probing commands with the help of a few YouTube videos, my final success for the evening being locating the centre of a circle.

I tried some digitising, and it looks like I've got a few spurious XYZ 0,0,0s in there, but otherwise the text file looks alright. I'll throw it into meshlab when I get a chance.

I was wondering if anyone could offer any advice on Z offsets when moving between the probe and a tool - I don't have toolholders so would need to touch off Z against a plate after a toolchange. How do I relate this to the Probe's data if using a surface map? Do I just have to look at the mechanical positions after touching off against the same reference and then do the maths, or are there any handy buttons in UCCNC which will take care of this?
