In the last G30 I've changed S6 with S-1 and I get:
G32 bed probe heights: -0.634 -0.719 -0.818 -0.339 -0.068 0.045, mean -0.422, deviation from mean 0.327

try redung the x300 value in your bed get to 290

I've adjusted the screw and now I got
G32
G32 bed probe heights: -0.369 -0.432 -0.442 -0.440 -0.284 -0.312, mean -0.380, deviation from mean 0.063It doesn't seem too bad, inst'it?
Now I'm starting to build the height mesh with G29 S0 let's see what happens
-
@the_dragonlord
only allows for max of 4 points

Here's my height map....looking at the graph it looks awful is it really so?

@the_dragonlord
that depends on the prints it produces. -

uh, yes, of course....now I'm printing a bed leveling test in wich start GCode I've placed:G28 XY ;Home XY
M561 ; Clear any bed transform that might be in place
G1 X165 Y165 ; Move Probe to middle of bed
G30 ; Do a single probe
G29 S1 ; load height map
G1 Z20.0 F6000 ; Move Z to 20we'll see....

That looks like it could be gantry sag rather than the bed being warped up. Regardless, mesh compensation should be able to correct for it. Only way to know for sure is to test.

Print twice. Once with G29 heightmap loaded and again without.
