      Yes, you're right, but I just can't understand why. It does not matter. Now it is OK.

      The problem now is understanding why the PanelDue works but doesn't seem to interact with the rest of the electronics. Maybe I need to update it?

        The PanelDue has also been updated.

        Now I have to check the engine settings.
        Tips?

            I have to verify the correctness of the settings, both for the stepper motors and for the remapping of the motors.
            I have 4 independent motors for the Z axis, each with its own optical sensor (which I am mounting now), placed more or less at the 4 vertices of the XY plane (the printing plane is fixed). I have to make the Z axis move in a coherent way .. reset it using the 4 sensors and manage it properly.

              That's quite easy with RRF3. All you need to do is connect your 4 z endstops, and then define the used pins in the M574 endstop configuration. And home Z as a single axis as normal.

                Everything starts moving ... and if it weren't for the power supply fan, you wouldn't hear anything (or almost)!

                very beautifull!

                  Good morning,

                  I got to the point where I have to set the zeroing of the Z axis considering the fact that I have 4 motors with 1 endstop each.

                  in my config.g I have inserted the following instructions:

                  M584 X0 Y1 Z5: 6: 7: 8 E3
                  
                  M574 Z1 S1 P "duex.e2stop + duex.e3stop + duex.e4stop + duex.e5stop"
                  

                  and this is my homez.g:

                  G91
                  G1 H2 Z5 F6000
                  G1 H1 Z-607 F360
                  G92 Z0
                  

                  How should I proceed?

                  I'm following these directions:
                  https://duet3d.dozuki.com/Guide/Independent+Z+motors+and+endstop+switches+in+RRF2/18

                  But it is not very clear to me what I actually have to do and I would not want to be wrong.

                  In order, the Z axes (Z1, Z2, Z3 and Z4) are positioned as follows:

                  Z1 = X0 Y0
                  Z2 = X0 Y600
                  Z3 = X600 Y600
                  Z4 = X600 Y0

                  Can you give me some advice?

                  Thank you

                  EDIT:

                  Maybe I need to enter the command
                  M671 in my config.g?

                  In my case it would be something like:

                  M671 X-115: -115: 715: 715 y130: 470: 470: 130; Z leadscrews are at
                  Z2 (-115.130) Z2 (-115.470), Z3 (715.470), Z4 (715.130)

                    delete the spaces

                    there is no leadscrew location required for this as the endstops determine the position.

                    just the normal z homing will do it

                      These are for RRF2.

                      I already linked the instructions for RRF3 above.

                        Good morning
                        It all seems to work quite well.
                        Now I just have to figure out how to solve a problem on the Y axis, mostly due to the type of "transmission" used and complete the settings ... before moving on to the print tests!

                        This is the X axis test: https://youtu.be/UG27txKxALk
