I have been reading through the Marlin website about ABL (Auto Bed Leveling) and I see what appears to be conflicting information.
At https://marlinfw.org/docs/features/auto_bed_leveling.html it states that running G28
(Auto Home) will turn off ABL and that to reactivate it you need to insert the code M420 S1
.
However at https://marlinfw.org/docs/gcode/G029-mbl.html it states:
G28
disables bed leveling. Follow withM420 S
to turn leveling on, or useRESTORE_LEVELING_AFTER_G28
to automatically keep leveling on afterG28
The latter is referring mostly to manual bed leveling, but in this section is referring to ABL.
So what is the difference between the S
and the S1
options?
