Ender 5 plus duet 2 upgrade



  • I am trying to figure out if I will be able to run dual z that the ender 5 plus has and dual extruder with my duet 2 wifi or if i would have to run an expansion card. Also how would I wire the heat bed because the ender 5 plus on gets the on signal from the board.

    duet2wifi comes with 5 steppers, if you want to run dual Z the way duet can (driving each motor separately, each side of the bed having own limit switch or bed probe leveling Z1 and Z2) then you have only one stepper driver left so only 1 extruder can be handled without expansion board.

    if you want to drive your 2 Z motors in series/parallel (like they are on the original board) then you can just plug them directly in to 2 Z motor sockets and you have 2 extruder drivers free so you can drive both 2 extruders and 2 Z motors from the duet2wifi

    Also how would I wire the heat bed because the ender 5 plus on gets the on signal from the board.

    not sure about this (I don't have the plus so no clue what you are talking about) but if the bed has it's own SSR you get the thermistor from the bed in to duet and you drive that SSR from duet's bed output, you just need to see if the voltages match (will not work 1/1 if SSR input for the bed is 5V and you hook it out to 24V output on duet)

    I don't know how the original board drives the motors, or how the motors are wired, but if you connect the two motors to the ZA and ZB connections, they are wired in SERIES, not parallel. This is important to know when it comes to setting the motor currents with M906. In series, you set the motor current to whatever the single motor current limit is; ie if you have a 1.6A motor, set the current between 50% and 80% of this, so M906 Z1200 (current in milliamps). If you wire the motors in parallel, by wiring them yourself (usually by connecting the same colour wires for both motors together in one plug, and connecting both to ZA), you need to DOUBLE the current setting, eg M906 Z2400 (which is the limit for Duet WiFi). In both cases, the stepper driver sorts out the correct voltage to send to each motor.

    For the bed, check the rating of your SSR. Most accept an input of 5-32V, but it should say on the SSR itself.

  • Thank you both I planned on hooking the 2 Z motors into each z slot Za and Zb the the extrudes to E0 and E1.

    You just wire it exactly like the original Creality board. The E5+ has an external mosfet switch wired to the regular hot bed output on the controller. Just remember polarity.
