RevF-Version-4
NOTE: If using on a dual-extruder model (such as the Metal Plus Dual), note that the hex file published below was built in error -- and uses an older copy of pins.h that does not support the second extruder. Use RevF-Version-5 or later.
Adjusts G29 probing points if the X or Y offset (M212) is greater than 10mm in either direction. This prevents Metal Plus from probing off-bed and thereafter gouging the build plate. Change requested by PBHQ.
