Stirling, the Z is a little of a red herring as I'm doing that manually at the moment to cut this mount which is for the Z axis.
Cheers Hood, I was doing exactly that, but on my main machine (no mill attached) and expecting everything to line up, tried it on the mill itself and it still looks offset but yep the cut is in the right place
So is it actually meant to line up material/cut on screen?
Thought I'd use pen and paper while I work things out, much cheaper and safer
showed a friend a video of it doing this and got the reply back "oooh, you've invented etcha sketch"....git
Someone should make a tool with a spring laoded pen at the bottom, then you can use it exactly as you would normally testing auto zeroing etc as it's metallic but it would draw rather than cut
