Z homing without a Z probe
-
Hi everyone,
I have recently added a new Aero extruder and have removed the inductive Z probe, I didn't use it for bed levelling as the surface is quite true.
I now have an issue where I can't home the bed anymore using the Z endstop microswitch. When I get to the Z level section in homeall I get a prompt for manual bed levelling. I have tried M558 P0 in the config file without success.
Any advice will be greatly appreciated.config.g below

It sounds like your homeall.g and homez.g files are set up to home Z using the Z probe, so you need to change them. See #1 at https://duet3d.com/wiki/Common_problems_and_their_solutions (I appreciate that the symptom you have is different).

Nailed it!
