Here's a routine I use that probes the "lower left" corner
of a part.
So, the probe is on the -X -Y corner.
It backs away a little in -X and then quickly probes in the
+X direction,
then backs off and repeats at a much slower speed, and then
sets #1001
to the offset between the probed position

Unless I am missing something, it should be a move back to the exact
point where the probe tripped?

Is G10 L20 any help here?
