      Hi,

      I got a HEVO running, but now I want to use 2 endstops, each for every z motor.

      Do I move the second z motor to E0 motor connector? (so z motor 2 on E0 and endstop at E0)
      Or just connect the endstop to the E0 endstop and the Z motor stays at the second z connector?

      If yes, the E0 moves to E1?

      Thanks

        Yes. You will need to define the second Z motor as the U axis while Z homing. There are other threads on this forum about how to do this.

            thanks, your code is working

            I think the M400 is needed, the code from
            https://duet3d.dozuki.com/Guide/Independent+Z+motors+and+endstop+switches/18?lang=en

            does not work, the Z switch never gets touched (E0 is touched). If I touch him manually bad Z value comes out(very high).
            With M400 is works!

            Thanks!

              Now this has been very helpful. Great post with actual wiring diagram attached and G code. Plan to take this home this weekend and print out the G code and search G code commands and get a better understanding of exactly what each line of code is doing (New to G Code), background is PLC and Automation but really getting interested in learning this.

                Actually this kind of post helps folks decide which product to use. Have not had a chance to hook anything up yet, just got the parts and leaving for a few days but have researched a lot of others and asked questions on the forum and sent emails and this one is by far the best.

                  Thanks, but please note:

                  All Parameters in the files (such as axle limits, accelerations, directions of rotation, etc.) are not final yet, as my printer is currently learning how to walk - and similar to children, at the moment it's still stumbling 🙂
