      Hey!

      I'm really new to 3d print. I'll actually wait for my tronxy x5s (corexy). It have 2 Z Stepper. That's not a problem, because we have one driver with 2 connectors.

      Now, I've see an video, where the bed could synchronized automatically. On every z-side was an endstop and the right z-stepper move the bed to top until the right z endstop will pressed and the left z-stepper move the bed "parallel" to top until the left z endstop will be pressed. Then the bed is leveled/synchronized. Here is the video: https://m.youtube.com/watch?t=317s&v=txZ5YuRMAzI

      Is such configuration with the duet 3d WiFi (and which expansion port?) Possible?

      Sorry for my English.

      Best regards. 🙂

        Hi!

        Check here https://www.duet3d.com/forum/thread.php?id=5006 how I did the same for my CNC with dual Y. You will have to use separate drivers for each stepper and do for Z what I did for Y. In principle, if all properly configured and with a proper homez.g file, you will see both Z steppers running in parallel until they hit the corresponding homing switches. My example also takes care of the slight positioning error as precisely installing the switches is not that simple.

        Anyway, my strong suggestion is to test this without the bed connected to the steppers and simulate yourself the home switches engaging.

        From what I know, CoreXY has to steppers for X/Y movement. If you have two more steppers for Z there are already 4 drivers in use. If you use only one extruder, the Duet3D WiFi should be enough. If more steppers need to be driven, consider adding one of the expansion boards.

          Thank you very much for your detailed informations. Actually I have one extruder, but I think, that I'll add an 2nd extruder. Where I must connect the 2nd z-endstop?

          Best regards. 🙂

            Connect it to the E0 endstop input. It will be the U axis endstop.
