Probe G code
Explanation:
G21G91 : metric, relative coordinates
G21G91 : metric, relative moves
G38.2Z-20F100 : probe Z-AXIS Down 20mm @ 100 mmpm
G0Z1 : move up 1 mm (it's in relative, not absolute, mode
G38.2Z-2F0 : probe 2 mm $ 100 mmpm
G9212.35 : probe thickness
G90 : back to absolute mode
G0Z25 : retract off the probe
This assumes that the user would position the probe, then jog the
bit 5 or 10mm above it. With a PDF this could be copied from the
pdf, pasted into Candle, and just the probe thickness changed.
