Mesh Bed Compensation Does Not Seem to Work

Arakahn

I will be referring to a previous thread, as I have the exact same issue and it was marked as Solved without an actual resolution posted:

So basically the probing works fine (sorta, need to tweak my piezo probing). The height map is there and quite uneven.

My start gcode seems to be ok:

G91 ; relative positioning
G1 H2 Z5 F6000 ; lift Z relative to current position
G90 ; absolute positioning
;G1 X70.5 Y-11 F6000 ; go to first probe point
;G30 ; home Z by probing the bed
G29 S1
M376 H10

When sending an M122 I can see that bed compensation is on and using the heightmap, but physically no compensation is happening (the Z axes are not moving at all during the print outside changing layers).

I am attaching my config and homing files. Any insight would be super appreciated

Is Z jerk 0 correct?

Can you show a screenshot of the heightmap display?

M376 H10

Have you tried turning off the taper? M376 H0?

Wow... talk about not seeing the forest from the trees.

I went over my settings 5 times, tried a bunch of things, and not ONCE did I even notice that. Probably changed my jerk and accidentally deleted the 5 from the 50 without noticing.

Thank you @Phaedrux!

If you don't mind I'll go get some rum and go feel stupid in my corner now.
