G29 S0 fails with "Must home printer before G29 bed probing"

strips

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.

Is U showing as in unhomed?

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

Yes, it did. That worked perfectly. Thanks!
