      Hi NexxCat

      I used the back off a sticker which is 0.1mm on my calipers.
      Just found my gauges !

      Thanks

        Hi,

        So I used the well 0.102 feeler gauge though it is .10 with my calipers and 3 times got 3 heights.
        I did video the whole process but that won't help me
        The numbers don't actually help because they are not accurate though one of them is:

        M98 P"0:/macros/Z probe report"
        Z probe trigger height set to -0.159 mm

        I don't think it's the effector because it does what it is supposed to do and no matter what trigger height I put in G31 line its the same outcome and the effector does return the same probe heights all be it not one after the other 🙂
        maybe the drivers are not calculating correctly I don't know but it is what it is and that is not usable.

        Cheers for your help.

        C

          Ok, last thing I can think of, just to double check if the actual positioning is being repeatable. Run these commands one at a time, or save it as a macro:

          ; Disable any baby-stepping and the bed mesh
          M290 R0 S0
          G29 S2
          
          ; Home the effector
          G28
          
          ; Heat bed to 60C & nozzle to 130C
          M104 S130 T0
          M190 S60 T0
          M109 S130 T0
          
          ; Run delta calibration
          G32
          
          ; Move the effector to 0,0,Max height
          G1 X0 Y0 F4500
          G1 Z500 F4500
          
          ; Move the effector back to 10mm off the bed
          G1 Z10 F4500
          
          ; Slowly move down to 0.1mm
          G1 Z0.1 F600
          

          When the macro is finished, the nozzle is at 0.1 on the Z axis. Use the paper or a 0.1mm feeler gauge and see if the nozzle truly is at 0.1mm

            Hi Ian,

            I used the original effector with the mag arms (printed the adapters) whats funny is I didn't even try to get anything level or square I literally slapped it together set the offset 1 level and it just worked.
            I have the effector still wired I can carefully attach it to the Duet2 and try it i cant fit the effector to the other board it's locked down
            but I've written this thing off now I don't expect this to ever work with duet but after spending all this time I do want to know whats wrong maybe it will help someone else some day...probably not

            I post a video of it once its fitted

            Thanks

                Hi NexxCat,

                No its 0.1mm to high

                  What is your current Z probe offset?

                      I can't remember offhand which way to adjust the offset to bring it closer, but try both of these, one will certainly be too high, but the other, does that give you a 0.1mm gap when running the macro I posted?

                      G31 P100 X0 Y0 Z-0.059
                      
                      G31 P100 X0 Y0 Z-0.259

                        They have all been tried

                        it's 0.05 to bring it closer dc42 suggested 0.05 so I've tried all the -0. possible infact the video I posted is -0.05

                          I know you've tried them whilst printing, but try -0.059 and run the macro. Is the gap 0.1mm?

                              So with -0.059, the gap is exactly 0.1mm after running the macro I posted. Correct?

                                  Ok, set that in your config. Then create the bed mesh with G29 S0. Once the mesh is complete, try to print the levelling model.

                                  I know you've done this so many times before, but let's try now we know the nozzle positioning is correct ok? Use the level_test.gcode I have you before, because I know it doesn't have anything in it to mess with the settings.

                                      It failed but it's too close to the bed just I think but its the best its ever looked.

                                        So it was sticking but not extruding because it was too close? Try changing the offset to say -0.1?

                                          Sorry been having net issues i'll adjust it 0.01 increments see if it works better.
                                          It was extruding and really sticking but as it did the next pass it was squishing too hard almost transparent and curling up at the outer edges indented in the middle as it cooled

                                          Thanks

                                            Hi NexxCat,

                                            Can I ask is Z hop enabled in the bed level test file you kindly sliced for me ?
                                            Or is that controlled via config.g ? ...so print files call M207: Retraction if Z hop is set on M207 in config.g Z hop is invoked on all Retractions ?

                                            Thanks
                                            C
