Addresses

Address	What it does
`X Y Z`	End point if no signal comes
`F`	Feed rate

How it works

Non-modal.

Example program

G00 G54 X0 Y0 Z.5 (ABOVE PART)
G31 Z-.5 F10. (PROBE DOWN)
G00 Z1. (RETRACT)

Example is in inch. Check offsets and clearances first.

Watch out for

Keep the feed low. A probe can break if it overtravels.
Probing on Brother is often done by maker macros. Check what your machine has.
