      Hi,

      I want to enable mesh bed leveling with IR probe but get this Error: Must home printer before G29 bed probing

      I have a suspicion this might have to do with my dual Z and U axis.

      Firmware Version: 1.18.1 (2017-04-09)

        Is U showing as in unhomed?

        If you do G92 U0 and then try to mesh level does it work?
