      @Rudy2A your mesh would benefit from more points. It's fairly sparse.

        votre maillage bénéficierait de plus de points. C'est assez clairsemé.

        For the sake of understanding, I prefer to use the P of M557 than S
        M557 X11: 250 Y11: 252 P4
        What would be the P value to make it more meaningful?

              Essayez double?

              Here, I get this result from M557 P4 to P8 ...

              The worst part is that by looking for solutions to my problem on the forum, I found quite a few cases similar to mine, but each time, the cases were not resolved or were not commented on final solution, it's a shame!

                As I said a little higher ... No matter the result of my height map by making a G29S0! My first layer does not receive any correction, the impression always remains identical in all the tests (and yet the height maps are never identical) ... same defect in the same place, it is frankly annoying not to understand!

                      Do you see the Z axis turning while it's printing?

                        Voyez-vous l'axe Z tourner pendant l'impression?

                        Yes absolutely, my CoreXY printer (it's my moving bed) has 2 Z axes. One Z on Za and the other on E1, I can see my Z axes turning indifferently during my print tests ...

                            I hate those types of couplers, as they behave like a spring.
                            But I think that in your case, the lead screw is fixed in Z by the upper bearing.

                              pouvez-vous publier une photo de la première couche?

                              here is... the quality of the photography is not great, but we can clearly see where my first layer is crushed, and where it is too high!

                              Whatever I do as a setting, it comes down to the same every time! it's like a model is in memory on the printer ...

                              Even if I level my bed using the adjustment screws with a print in progress, I manage to have a very appreciable result ... Only, when I launch a new print test (without restarting the printer) my settings are not taken into account and we start again on a leveling of the bed almost identical to the photograph above!

                                post the picture of the mesh grid.
                                while printing check with m122 that mesh grid is active.

                                    for a glass surface, that looks absutly terrible. there might be a problem with your probe.

                                        for a glass surface, that looks absutly terrible. there might be a problem with your probe.
                                        please run this macro.

                                          @Rudy2A, you said in an earlier post that you are using the IR sensor as Z probe. That would explain your results. You won't get good results from the IR sensor on that bed, because of the white print on the black background. If you put a sheet of matt black paper between the bed plate and the glass, then you may get acceptable results.
