      You can drag and drop the config.g onto the post box to upload it here. Or even copy and paste the text here.

            I see you have no ideea what you are doing there. Dont know why you used R parameter. I think that is for a delta printer.
            If you understand what I am saying (as I think you are translating online from chinese), try something like this:

            M557 X10:180 Y10:180 S40 
            

            You will have a 16 point mesh bed.
            However,

            M557 X10:180 Y10:180 S4:4  
            

            may cover better the area, also, with 16 points mesh bed.

              No I’m not from China. It’s just this thing is actually a gift to me and I can just got thrown it after they set it up. I will try putting in that code and then give you an update. thanks😄

                All right, so I tried both those inputs, but it did the same problem. Is there any more information you need?

                  If you will put here the files, either as code or copy pasted, as well as a short clip with the problem, I am sure that they will be many to help much better than me. I am sorry, but it is difficult otherwise.
                  PS. It is not a problem if you eventually are from China, I just expressed the feeling that you do not understand what we are saying, wich is usually because a language barrier.
                  PS2. Do not insert those files as images/screen captures, as probably some of them will not fit on your monitor (I see that your config files start at line 46). Unless ... you will rotate the monitor to portrait, if you insist with screen captures.
                  PS3. There is also the possibility that the printer has an hardware issue, so.... files and clip needed.
                  PS4. Normally, it should have been a difference between your M557 and mine. Maybe you can show how the original M557 was (assuming it was the original).
                  PS5. If you do not try to do mesh, the printer works right?

                    Honestly at this point I’d rather like to know how to completely eradicate the height map system so it forgets about it.
                    PS, I am not from china I am in the US and I am quite new to this

                      Honestly at this point I’d rather like to know how to completely eradicate the height map system so it forgets about it.

                      At the end of your config.g are these three lines:

                      ...
                      T0 P0
                      G29 S1
                      M501
                      

                      The G29 S1 loads the mesh file called /sys/heightmap.csv, which is usually the last mesh created. If you comment that out (ie put a semicolon like ; at the beginning of the line) or just delete it, no mesh will be loaded.

                      However, I think the original problem of your bed mesh probe starting "in an area without anything under it" is caused by your probe offset. This is defined by the G31 command in the probe section, and more specifically I think the X and Y coordinates are incorrect. Currently you have:

                      ; Z-Probe
                      M950 S0 C"Servo0"                               ; create servo pin 0 for BLTouch
                      M558 P9 C"^probe" H5 F800 T20000                ; set Z probe type to bltouch and the dive height + speeds
                      M557 X10:180 Y10:180 R-1 P2:2                      ; define mesh grid   
                      G31 P500 X-40 Y10 Z4.3                           ; set Z probe trigger value, offset and trigger height 
                      

                      To get them correct, see https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_testing#measuring-probe-x-y-offset. The whole page is worth a read.

                      I've taken the liberty of adding your config.g, config-override.g and bed.g to your posts as text (cut and pasted from the files on Google Drive). We couldn't see the full config.g in your screenshots.

                        Indeed, -40 it is much, but if the printer is something like a ”classic” Ender:

                        ender.jpg

                        this may be it. Y=10 is almost sure ok, this is why I asked for some clip/photo.
                        Probably erasing G29 is the best Ideea, anyway...

                          @soare0 yes but do you have a way of actually achieving the erase of the height map/G29

                            @Mythbear74 Del or Back keys on your keyboard?
                            And if you are not able at least to submit a photo with your printer or a clip with its behaviour, I am very doubtful that anybody will be able to help you with this.
                            Maybe Deanna Troy's mother, as she is a good mind reader ...

                              @Mythbear74 The default heightmap is stored in the /sys folder with the name 'heightmap.csv'. In DWC, go to Files > System > System Directory, right click heightmap.csv, and select Delete.

                              But it is unnecessary, really. If you remove the G29 from config.g, it just won't load, and won't be used. RRF will report 'None' for 'Compensation in use'. If you send G29, it will try to create a new mesh based on the M557 command in config.g, so if you don't want that, delete that too.

                              However, all of this means that you won't be able to compensate for the bed not being perfectly flat.

                                    The last to the right button on the button row. It is true that I do not know maximum size, so maybe you will do mp4 or such?
                                    I selcted it, to be more clear...
