      Apparently, it seems to be out of order (to watch out for) ...

      I still have a slight problem calibrating my probe (mini IR).

      When it raises its value.=>>
      "Nozzle in the center of the bed (usual temperature)
      Put the nozzle in contact with the tray (or the sheet of paper)
      G92 Z0 (Z = 0)
      Lift the 5mm nozzle (G92 Z5)
      G30 S-1
      Read the z value
      G31 Z xxx"

      I get a height of 2.74 and if I indicate this value G31 Z2.72 my first layer is too crushed ... On the other hand if I go down to 2.62 in manual G31 Z2.62, it is good. Is such a Delta normal?

      I am in doubt about my order for the probe, does this seem correct to you?

      ; Z-Probe
      M558 P1 C"zprobe.in+zprobe.mod" H5 F120 T6000 ; set Z probe type to unmodulated and the dive height + speeds
      G31 P500 X-19 Y6 Z2.62

      Thank you one more for your help!

        yes, the first step is just to get a close value.
        fine adjustment should always be made afterwards.

          Thank's @Veti

          A small clarification on my values.

          If I adjust my leveling on 2 points, my first coat is impeccable. (probe at the four corners of the bed) M557 X11: 250 Y11: 252 P2

          If I adjust my leveling on 3 points, my first layer is much too high (probe at the four corners and in the center) M557 X11: 250 Y11: 252 P3

          Please note that this is the same part that I am printing and no changes have been made.

            It depends if you bed is perfectly flat.

            If true, g32 is enought
            if false, g32 + g29 is needed.

              In both cases I do a G 32 + G29, all in a bed.g file

              ; bed.g

              G28 ; Home all Axes
              M561 ; Efface la correction de plan
              M290 R0 S0 ; Efface Baby-stepping

              ; Bed levelling (G32)
              G30 P0 X0.0 Y132 Z-99999; sonde près d'une vis sans fin, à mi-chemin le long de l'axe Y
              G30 P1 X260 Y132 Z-99999 S2; sonde près d'une vis et calibrez 2 moteurs

              ; Espace de sondage
              M557 X11:250 Y11:252 P2 ; Définir la grille maillée

              ; Compensation de maillage (G29)
              G29 S0

                i dont think that the bed.g should contain a G29. or a M557 .

                if you cant G32 + G29 you should create a macro

                  You may want to add a single G30 at the center of the bed after the G30 P0 G30 P1 lines so that any change in height caused by the tilt correction is captured before the heightmap is created.

                    I did not understand everything ... Like that?

                      G90 ; absolute positioning
                      G1 X150 Y150 ; move to center of bed
                      G30 ; probe bed

                      Change the x150 y150 to be whatever values you need to move the probe to the center of the bed.
