G31 P500 X39 Y0 Z1.538 ; set Z probe trigger value, offset and trigger height
you specified that your probe is to the right of the nozzle, but the picture shows its on the left

M98 P"0:/macros/Bel leveling assistant"
Error: Calibration failed, computed corrections: nan nan nan nan nan nanM98 maybe because I've made a Macro but if I send G32 directly the result is the same
G32

@the_dragonlord
execute each statement manually and see which one fails

I've lunched the G30 manually one by one and none of them gave me the error but when I run G32 it appears the error
-
@the_dragonlord
no why are you running the G32?

to have an idea on how to adjust the 6 screws.....wouldn't be this the purpose of G32?

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

uh, that was the problem...ok, thanks

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....
