M500 dont work?
-
Hi there,
i have a problem with leveling my Z.
i do this to level the Z
M561
M208 S1 Z-3
G1 Z1
then move the nozzle 3 steps down
G92 Z0 because it needs more down
move 2 more steps down
then the nozzle is a paper thick from my bed.
M500 to save itthen G30 S-1 to see if it works
and then it goes the same as when i start
i have a config_overide.g but there is no code that related to this only my pid tune
-
M500 only saves parameters that are determined automatically, for example by tuning and auto calibration. It used to save the G31 Z probe trigger height value too, but we removed that by default because it was confusing too many users. So you need to measure the Z probe trigger height and edit that value into the G31 command in config.g using the System Editor page of DWC.

@dc42 the trigger height i already put there, sorry i forgot to say
G31 P25 X-10 Y-50 Z-2.332 ; Z probe trigger value, offset in relation to nozzle.

@mickey30m said in M5000 dont work?:
G31 P25 X-10 Y-50 Z-2.332 ; Z probe trigger value, offset in relation to nozzle.
A trigger height of Z-2.332 doesn't make sense because it means that the probe triggers when the nozzle is 2.332mm below the bed surface.
-
@dc42 so it needs a postive value?

Yes, except for nozzle-to-bed contact sensors.
