    Question:
    Can the meshlevelling handle this or not?

      After many hours of testing different settings I have made following observation.

      My large printbed shows in below image that I have issues with the effector is that it bows far out of pattern points.

      I think it is the way extruder is mounted on effector makes it unstable.

      Have to rethink how to get the extruder mounted to minimize the total effector weight.

      Any ideas you guys have to share is welcome.

        Did you run a Auto calibration?

        G32
        

        Did you tune those two things?

          G32 Yes several times saved M500

          M665/M666 Tune? (Aint the tune done with G32 with saved values in config-override?)

            Still hoping to get answers to this question

            What + - range can be done?

              @tecno your orbiter mounting is not good...I already told you on the other thread you asked...the orbiter mounting can't be in contact with the strain gauge of the smart effector because will not work properly, it only need to be connected with the 3 point mount holes and not the entire surface!

                  Seems to be a hot potatoe as nobody cares to answer the range of functional mesh compensation.

                    @tecno The mesh compensation can probably account for the bed deviation (from memory there isn't any practical limit), but what is the reason the bed is deformed? Most likely is effector tilt. Have a look at http://boim.com/DeltaUtil/CalDoc/Calibration.html and see if any of those examples match your bed shape. I assume you have been through this page too: https://docs.duet3d.com/en/User_manual/Tuning/Delta_calibration

                    Any reason you're using a square mesh, rather than a round one? If you have a round bed (and you may have a square one) your M557 should have an R parameter rather than X and Y, eg M557 R130 S20
                    See https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_mesh_bed#define-the-mesh-size-and-spacing

                            Actually, it's the probe spacing S80 (ie 80mm) that is causing it to be square. It can't get into the edges with that value.

                                @tecno There definitely seems to be a lot of variation in the measurements. Your current probe setup is:

                                M558 P8 R0.4 C"io3.in+io4.out" H50 F1200
                                

                                See M558 in the Gcode dictionary. I'd say reduce the probe feed speed (F) down to something slower (my delta probes at 120, but it isn't a smart effector) (see following post). You can always have a fast travel speed (T, which is missing from yours). Reduce the dive height (H) to speed up probing, doesn't need to lift 50mm each time. And you can probe multiple times (A) to improve accuracy based on tolerance (S). I'd try something like:

                                M558 P8 R0.4 C"io3.in+io4.out" H10 F1200 T6000 A5
                                

                                Use that and see if you get a smoother mesh. It's difficult to tell what else is going on otherwise.

                                  @tecno Sorry, the docs say to use F1200, so keep that for now. If the bed mesh doesn't improve with the other settings, try varying this speed, as it is possible the weight of the extruder makes a difference.

                                    So I think that no extruder is working directly on the effector

                                      I have now tried to get the Smart Effector to work properly but no.

                                      M672 is now set to 10:245 and still I do not get all points probed.

                                      Only my Phaetus Dragon water cooled is mounted on the board.
