Mesh compensation no longer working in RRF3

gamer_013

I use an inductive sensor wired to the e0stop and I used to be able to do mesh compensation and use the bed leveling assistant but now it's giving me the error G30: Z probe 0 not found. It looks like G29/30 can only use probe 0 which look like it should be setup by default from the wiki on M558. Is my "Z probe connected to E0 endstop input" not a z probe? Or how should I perform G29/G32 operations now?

Your issue if you're trying to set the same pin as a z endstop and a z probe.

Just remove the M574 for Z

M574 Z1 S1 P"!e0stop"

replace with
M574 Z1 S2 ; configure Z-probe endstop for low end on Z

Hi,

JOOC why are you not using the Z-probe connector?

Removing this line gives me a "failed to enable endstops" error when trying to home Z.

That did it! I didn't think so try that as the gcode wiki said "The S2 option of M574 is intended for use only when axes other than Z are using the Z probe for homing." Which confused me because I was using my "z probe" to home the z axis so I didn't consider the S2 option. Thank you!

This is carried over from an old config that I used long ago and the example happened to have it setup that way. I may convert it over when I get some time to re-configure my printer.
