Park the nozzle at a predefined XYZ position.
The park position is defined by NOZZLE_PARK_POINT.
Z axis action
If current Z-pos is lower than Z-park then the nozzle will be raised to reach Z-park height
No matter the current Z-pos, the nozzle will be raised/lowered to reach Z-park height
The nozzle height will be raised by Z-park amount but never going over the machine’s limit of Z_MAX_POS
The most basic example is to use the command without any arguments, which raises Z by the default distance and moves to the parking position.
G27 ; Raise Z if lower
This one is useful as an end script, simply raising Z and parking.
G27 P2 ; Always raise Z
