    I just got this height map after adjusting on of the X-Axis eccentric nuts

    That looks much better. If you now level your bed more precisely, you're done.

        And the macro method is used to level the bed right?

          I think 400 measuring points (With a print bed size of 350x350mm) is absolute overkill

          That depends: to verify the surface of your print bed, it's fine, but I agree that it consumes way too much time if you create a new mesh frequently, e.g. from your start.g.

          I agree.
          It's too much for everyday use, but to find out exactly how my record looks, especially if you plan to grind the record to see where you can grind more and where not... then I would also go to more measuring points to tend.

                Yes, exactly.
                Read it to decide if it's something for you.
                At least I will no longer manually adjust my print bed with a sheet of paper or a spring steel sheet.
                I only need a spring steel sheet (feeler gauge) once to determine the Z offset, and then never again... unless I change the nozzle. 😁

                Ein Federstahlblech (Fühlerlehre) brauche ich nur einmal um den Z-Offset zu ermitteln, danach nie wieder... außer ich wechsel die Düse. 😁

                          @infiniteloop, @Günter-Jibben I keep getting the Z-Datum error, and I keep setting Z=0 to where a 0.04mm gauge will fit in, but it still gives me the error

                            I keep setting G92 Z0, but whenever the printer finishes probing or I restart the printer, it goes back to old height

                              @Günter-Jibben @infiniteloop Actual Z0 for me is -1.35 from where it is now. I set it as Z=0 using G92 Z0, but it keeps going back to the original position, after probing and after restarting the printer.

                                @tratoon if you are using a probe, you shouldn't be using G92.

                                Set the z offset of your probe correctly in G31 in config.g. your z axis will be set to this value when the probe triggers

                                  @engikeneer But to get a Z offset, don't I need to tell the printer where Z0 is and isn't G92 telling the printer where Z0 is?

                                    @engikeneer So will my printer always set Z0 to where the probe is triggered, and I have to ell it (using the Z offset) where to put the nozzle in relation to the Z0, set by the probe?

                                      @engikeneer And how do I stop a " the height map has a substantial Z offset. Suggest use Z-probe to establish Z=0 datum, then re-probe the mesh.
                                      30 points probed, min error -1.656, max error -1.329, mean -1.461, deviation 0.088
                                      Height map saved to file 0:/sys/heightmap.csv" warning?

                                        @tratoon you can use G92 once when determining the z offset, but not after.

                                        My preferred approach is to set G31 Z0 (I.e. zero offset). Then probe the centre of the bed with a single G30. Then move z down until the nozzle just touches your bed. For a BLTouch, should be 1-2mm ish. Whatever that value is goes in G31 Z

                                        You can then tweak it a little bit if you find your first layer is too squished, or not squished enough
