Bed Levening Ennder3 BL-Touch not level
-
I am able to
- Home all
- "run mesh compensation G29"
- "True bed leveling G32"
however only one side of the bed is leveled the other the head will scrape the surface.
By the way it works perfectly if I:
- home all
- manual level
What have I done wrong?

@john345463563, you should run true bed levelling (G32) before you run mesh bed compensation (G29). Otherwise the mesh will compensate for the bed as it was before you ran G32 to level it.
The order in which you have defined Z motors in M584 must be the same as the order in which you have defined leadscrew positions in M671. Try running G32 more than once and look at the reported corrections. They should reduce with each run. If they increase instead, you have defined those two sets of parameters in different orders.
