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.

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.
