@justus2342 I run G32 and G29 S1 to enable mesh levelling which is not always need if your bed is in good shape and level I dont run G29 everytime as it stores the heightmap I run G29 if something has change ...nozzle, effector but only then Yes you need to make sure the nozzle is clean as it cant account for plastic on the nozzle. You can run G30 S-1 to do a single probe as a minimum for G29 S1 to be effective Hope this helps
