Need a little help with Melzi to Duet3d Wifi Upgrade please?



  • I am in the process of upgrading my Wanhao Duplicator i3 v2.1 from the factory Melzi board to a Duet3D Wifi. I have been following the process as laid out in the "Wiring your Duet" document, but appear to be left with two cables. I am not sure where the corresponding connections are on the Duet3D WiFi.

    The first cable is marked (on the Melzi board) as "E Motor" which I had taken to be the extruder motor. It is a 4 core cable and ends in a green block connector. The cables each have a screw in connector style.

    The second cable is marked "E Temp", which I have taken to mean "Extruder Temp". This one is a two core cable.

    Has anyone done this upgrade and would you be able to point me in the right direction with regards to these final connections please?

    Connect that none to the E0 motor output on the Duet.

    Connect that one to the E0 Temp connector on the Duet.



  • Thank you so much for the speedy response, It's very much appreciate it 🙂
