Probe for corner

I've been using the subroutine and it's great! There are a couple of improvements I would like to suggest:
1. the move after finding the y edge should be on a diagonal rather than first X, then Y.
2. The Z touch off is great, but since tool length compensation(G40) has been toggled off, I have to then load the tool length for the probe (G43) manually.

I'll try to do the edits myself and repost them. Thanks again for setting this up to begin with.

Glad you are having some fun with it. edit, test, improve for a better mouse trap.

I'm unable to get this to work, and I think I'm not understanding something here. FYI, I'm running a Tormach with a touch probe that works properly (I can do g38.x moves in MDI and it works as expected). I have my probe positioned so that the first Y move will make contact with the workpiece. When it does, it halts with an error message "Probe not complete unexpected Y hit on retract." I'm reading the source but it's not clear to me why this is happening. Would also be great if anyone could expand just a tiny bit on the parameters--I am trying to run this using the defaults as they look vaguely right... Thanks!

My SWAG is your retract is not far enough for your probe hysteresis.

Thanks John. I set the retract to an absurdly large value like .25, and I get the same result FWIW, the hysteresis on the probe is visually imperceptible to me.
