    forgive me for the bad english done by google.
    I have a corexy that I build, a 300x300 table with 2 4mm pitch spindles and 4 10mm rods with lm10. Duet 2 wifi firmware 3
    I've been following the forum for a long time and I'm familiar with the reprap but I have a problem with bl touch that I can't solve, please help me.
    I can use my machine normally when the piece is small but when it occupies the entire table I have problems.
    I do the readings with a bltouch every 50mm in x and y, I have a precise mesh, I redo the measurements and I get the same results, when I print a large piece, I notice that at times the filament gets too tight on the table and in others barely group because the beak is high.
    I also follow the movements of 2 spindles looking at the mesh generated in the DWC, and it seems that the movements of the motors correspond to the irregularities in the table, but on the impression this does not seem to happen.
    So, I have a whole mesh reading system working perfectly, but it’s not as efficient on the whole table. I do not know what to do, I have checked several times all the mechanical system of the machine and everything is ok, I would like to know from you if there is something I can check.

    currently when i have to print on the whole table i follow the entire first layer and keep changing the extrusion factor to compensate for the difference in height.
    again i reaffirm some items: bltouch with repeatability in readings ok, z axis adjusted and nothing is screwing or heavy. the x and y axes are also ok they are not going down. not what I can try to do.

      Hi,

      Please post your heightmap.csv file.

      Thanks.

        I now send photos of a test that I do, there are some squares inside each other, with 0.4mm space between them, the largest square is 280mm, line height is 0.3mm, the motors compensate according to the mesh generated by bltouch but in practice the layer is irregular.

            Thanks.

            Try printing a test from 50 to 250 on both X and Y.

            That should put it away from the edges which are the highest parts.

                Thanks.

                It looks a bit better.

                Did you create the height map with the bed heated to a typical temperature you would commonly use?

                If not try re-creating the height map with the bed heated.

                  yes, i have 3 height maps created for each material i use, at different temperatures, and i update them almost every day

                    Are you sure your probe offsets are correct?

                    -X to the left of the nozzle, +X to the right
                    -Y to the front of the nozzle, +Y to the back

                      @Phaedrux yes this is correct, thanks for the tip. I've really looked at a lot, the reprap code is not so complicated now for me but I still don't know what may be happening. can speed, acceleration or jerk on the z axis influence?

                        Are you doing independent lead screw leveling as well?

                        Where you have double Z values you shouldn't. The Z axis is a single axis, so remove the double values. Ex: Z1150:1150

                        E416,5

                        Your E steps per mm has a comma instead of a period.

                        Can you send M98 P"config.g" and post the results?

                        Also post your homeall and your slicer start gcode.

                          my steps are really wrong, thanks!
                          should I remove all double settings for the second z?
                          yes, I do the leveling by optical endstop on each axis then I do it again by bltouch.

                          I made corrections

                            @RODOKAS said in problem with irregular bltouch mesh:

                            should I remove all double settings for the second z?

                            Yes. It's not really a second Z. There is only 1 Z axis, even if made up of multiple motors. If you want to control the motors separately, you'd need to create an entirely separate axis like U and then you'd have settings for that axis. In fact, before RRF3 you would have needed to do that to do the dual endstop leveling and home each axis separately and then recombine into a single Z axis.

                            I should have asked for your bed.g as well.

                                  Hi,

                                  • It doesn't seem as if your homing macro is setting the Z=0 datum using G30
                                  • As I recall you don't need to use G29 S2 right before using G29 S0 - it won't cause problems if you leave it
                                  • You don't need to use G29 S1 to load the just created height map, the map is still active
                                  • What is the point of the M500?

                                  Frederick

                                    I was curious about the m561 in my beg.g and took it out to test it, did the mesh in abs again and restarted the machine to make sure, I did the same print test as before and the result was the same.

                                      Your homeall doesn't have a z homing component, so please post homez as well.

                                      Where are you doing the Z axis leveling? In homez?

                                      Could you post all of your files in a single post? That would make it much easier to see what's going on without having to scroll around all over the place. The only way we can see what's going on is be looking at the gcode.

                                          It doesn't do anything in this case because there hasn't been anything calculated or measured to save to config-override.g.
