@oliof so you saying that G31 has the wrong X and Y values?
G31 P1000 X23 Y5 Z0.1

@droftarts Sorry for the late reply, with the end of the year/vacations, etc I didn't have the proper time to reply and work on this printer problem. Bellow the pictures asked.
The bed is warped (I used a light source below the ruler to see it better but the bed compensation should compensate for that no?)

@droftarts
As i understood to make the mesh manually the nozzle will travel to the first position then it waits for me to jog the Z and then I should click somewhere or send some command right? i tried to look for this and didn't found.
I have 3D printers since 2011 and i followed the innovations closely. I have a Cartesian (duet) with BLtouch that works fine, i don't touch the bed for years.
Maybe I need to flash the duet again?

@droftarts This mesh.g is a non-ending loop
I am in a death end
I don't know what to do next, get a new bed? the firmware should compensate the difference on a 130mm cube its not even on the entire bed, its on a small 130mm cube
I still believe there is something wrong with software, its not hardware

@fcwilt said in G32 doesnt save after True Bed Leveling:

In any case you have been using G32 to do automatic bed leveling using the two Z steppers.

I don't have mesh.g can you share it please?

@droftarts ![alt

The picture of the axis
Since i don't use mesh.g maybe its a good idea to try it?
I tried to manually do the mesh but with G29 k1 but didn't find in the documentation how can i validate each position

@droftarts Yes, he bed compensation is enabled with the M375 P"heightmap.csv"

Is the superpinda correctly defined?
M558 P5 C"^zprobe.in" H5 F300 T8000 A3 S0.03 ; set z probe to SuperPINDA\

Maybe i need to get a glass and try it out, with glass or mirror the flatness must be perfect.

@droftarts I set the M208 Z-1 but the outcome its the same
The only solution is to source a new bed?
Thank you

@fcwilt Will try that thank you sir

@droftarts That the issue, the print is ok in the middle but not okay in the corners, adjusting the Z trigger won't solve that problem.

@droftarts you are right the Z on G31 its 0.5 instead of -3.
@fcwilt i am in Europe its a very expensive to buy from USA
The correct G31 is Z0.5

Any other anything else I can try to have the calibrated mesh working? maybe start with a new bed?

@fcwilt The bed is from AL plates cut in laser maybe i need to get it from another supplier, aliexpress?
The Gcode is the start Gcode on the slicer.

@droftarts I understand what you are suggesting and i will add the line to let the Z go bellow zero 1mm but it wont affect this behaviour because as you can see in the 1 layer print the nozzle its already too close to the bed; i want to figure out why and how to solve it

@fcwilt Thanks frederick.
Yes, i am printing with compensation enabled, dunno why it doesn't compensate :S The bed is awful, I don't know how can a thick AL plate have these waves, it's strange. Anyway the bed compensation should compensate for all of this no?
This is my starting gcode:
G31 P25 X31 Y4 Z0.50
G28
;M572 D0 S0.6 ;pressure advance
M190 S75
M375 P"heightmap.csv"
M109 S250 T0
G92 E0
;G1 E75 F100 extrude filament line
G0 X100 Y0 F9000 ; Go to front
G0 Z0.15 ; Drop to bed
G92 E0 ; zero the extruded length
G1 X40 E25 F500 ; Extrude 25mm of filament in a 4cm line
G92 E0 ; zero the extruded length
G1 E-1 F500 ; Retract a little
G1 X80 F4000 ; Quickly wipe away from the filament line
G1 Z0.3 ; Raise and begin printing.
G92 E0

Note: it won't solve the problem but if i get a new bed... maybe its the PEI or the magnet stick below the PEI.

@droftarts the mesh

@fcwilt
Screen of the 1st layer of a small cube. In the center it’s ok, 1 corner too far away and the other too close 

@fcwilt after several iterations and tryouts the problem is still there.
I can’t calibrate the first layer, the difference in the bed is very high… I dunno if it’s the compensation or something else. That’s why I was saying that the calibration wasn’t saved. I can post a picture of the printed 1st layer…
The mesh didn’t help btw @droftarts

@droftarts Just trying to be able to print correctly the first layer on the entire 300mm bed
I made a new macro and its correct, without the g28 it doesn't correct anymore.
How do you suggest starting the print? Like this?

G28 XY
M561 ; Clear any bed transform
G1 X1... Y... ; Move Probe to middle of bed
G30
G29 S1

What about G32 using absolute position instead of relative?

@droftarts Will do it and record a video as well because after the first iteration only the right motor gets calibrated.
I will create another macro without G28 to see.

@droftarts i think finally i understood what you said, you say that the points on both Z leadscrews are at the same position relative to Z0 and leveled but they are not, the bed is 0,6mm off on the right. How should it look like my bed.g and homeall.g ?
