M420 - Bed Leveling State

Description

Get and/or set the enabled state of bed leveling compensation, plus Z fade height.

This command has been extended with L to load a mesh for Unified Bed Leveling.

Notes

The “current position” may change in response to M420 Sn.

G28 disables bed leveling. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28.
