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 it

then 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.
