Hi guys. I'm pretty new to Klipper/MainSail and have been trying to get my printer (Ender 3 V2, I upgraded with the Creality Direct Drive and CR Touch) up and running

I'm trying to level the bed and when I calibrate it I get this heightmap. I'm not quite sure how to interpret this. Should I be loosening all 4 screws to get it to the same level as the white plane? Did I set my Z offset incorrectly?

Any help is greatly appreciated

A bed mesh is not there that you level your bed according to it. For that you would use BED_SCREWS_ADJUST:

With the log, we can better interpret the results of the mesh

Did you adjust your knobs and made multiple meshes?

#

As tehre are multiple meshes and they are all over the place

#

So ig you just homed once. Then made a mesh, adjusted your screws, made another mesh, adjusted the screws and so on.
So basically your 0 coordinate was made before that first mesh. Therefore all other meshes after that are relative to that homing at the beginning.

#

So you most likely tighten the screws previously without rehoming z and that's why the bed is below 0 now

Okay I think I understand, so what's the best way to correct this?

Either rehome z to get a correct mesh or like I already wrote there: #1225456903610437662 message
