Duet 2 wifi wiring connections to CR-10 questions



  • Hi all,

    first of all id like to say that I am new to this forum and have tried to search a little bit for the answer to my query to no avail.

    I have several related questions to connecting the duet 2 wifi to a CR-10 and I cant seem to find a how-to or guide.

    any here are my queries.

    1. do the original connectors for the cr-10 stepper motors fit the duet board, if not is there a pin out diagram that anyone has that can assist me to rewire a new connector, bearing in mind the wiring from the original stepper is all black.

    2. the duet board calls for a 3 pin connector for the axis end stop switches but the cr-10 is only 2 wire, again can anyone provide guidance on this.

    3. I am going to use the PSU that came with the CR-10, I assume the small control board that is mounted to the back of the case is no longer required for the bed heater and I can wire the bed directly from the board.

    thanks.

    The CR10 and the Ender 3 are very similar. Take a look through these guides, it may answer some of your questions.

    No, the connectors are different but the DUet comes with a full set of shells and pins. YOu will need a proper crimper. The wiring is pretty straight forward - look at https://duet3d.dozuki.com/Wiki/Duet_Wiring_Diagrams for the Duet pinout. I am sure there is a similar pinout available on the internet for the CR10 (there are a number of different boards in the CR-10)
    Having said that, it is really straight forward even if you didn't have the CR10 board present. Just look at where the wires are going. A multi meter is a great help to check which wire goes with which.

    1. the duet board calls for a 3 pin connector for the axis end stop switches but the cr-10 is only 2 wire, again can anyone provide guidance on this.

    The CR10 uses a switch that connects the two wires together.
    This is the bible: https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches
    The third wire is 3.3V for any end stop that requires power. It is not used for the CR10. Connect the end stop switch to the ground line through the micro switch.

    Yes
