      I suggest you read this article http://boim.com/DeltaUtil/CalDoc/Calibration.html which shows well what kind of errors in probing are introduced by what mechanical issues and take it from there.

        ok thanks I don't think I understand correctly I send you a photo to understand better
        the part where it does not print well (too low) should I raise the values that I put in the square?

          @nemecek you could do that, or run the delta autocalibration multiple times until it converges to flat printing

            @oliof OK thanks. when you talk about delta calibration. you mean the G32 to do it several times?

              @nemecek yes until the numbers stop changing. If they don't stop changing after 4 it 5 runs you very likely have a mechanical issue (something loose, backlash, whatever) you need to solve.

                    no guys it's not a mechanical problem I think that even if you load the map not the law doesn't correct there is little error in the level you can see it with the photos I sent you. I say this because I only print with the G32 and it is the same as when I also send the identical G29 nothing changes .. I can't understand what's wrong. Is it normal that here where I highlighted it doesn't activate and always like this? is my start print script correct?

                      The highlighted item being greyed out is ok because It's referring to a different means of compensation. You are using mesh compensation (it shows it as active "compensation in use" mesh" To disable it you would use "disabled mesh compensation (g29 S2)"

                        @Phaedrux hello agree so here is fine. can you please tell me if my start script is correct?

                              I'm afraid the issue is with the calibration and mesh creation being inaccurate due to mechanical issues. Some things software can't correct for.

                                I also tried to lower 40% of the values in the map where I highlighted in the photo above ...
                                without success I have not noticed any difference

                                  and how is it possible then that without the map doing only the G32 and putting a thickness of paper folded in 2 under the plate I adjust only the height print well😮

                                    If it's printing well without G29, why use G29?

                                    The combination of probe offset from the nozzle and effector tilt varying with position can lead to probed points being inaccurate.

                                      yes I understand but something should change if I change the values of the map manually instead nothing changes ok thanks for everything I keep the thickness of cards under the plate🤔

                                        G29 S1 P "heightmap.csv"

                                        Do you have multiple saves heightmaps?

                                        Try deleting your current heightmap entirely from the /sys folder
                                        Then recreate it with a fresh calibration run and then a G29
                                        and then use just G29 S1 to load the default heightmap.
