Andy may have a better idea, but I would explore the idea of running a named subroutine that captures the machines current xy position, (so you can run it up the post and return to the saved xy position) moves to the contact pad, starts the spindle slowly in reverse so it doesn't cut the pad, does the g38.2, and uses the results to set the coordinate system Z, probably with an offset from the known height of the pad. I use un-etched pcb material for the pad which is about 1/16" thick. 99% of this, var #numbers etc is in the Documentation.pdf. Okular will be your friend.
