Duex5 Extruders not working



  • I have a duex5 attached to a Duet Wifi with firmware 2.00 and cannot get the stepper motors of the extruders to work. Currently the paneldue displays the thermistor readings appropriately for thermistor 1 and 2 of the Duex5, which leads me to believe that the Duex5 is wired correctly. To control the motors I try the following code:

    From config:
    M569 P5 S1 ; Drive 5 (includes x,y, and z motors) in reverse

    M305 P3 T100000 B4138 C0 R4700 ; Set heater values (naming does not include x, y, and z motors but does include the bed)
    M143 H3 S280 ; Set temperature limit (again excluding x, y, and z but including the bed)

    M563 P2 D2 H3 ; Define tool 2
    G10 P2 X0 Y0 Z0 ; Set tool 2 axis offsets
    G10 P2 R0 S0 ; Set initial tool 2 active and standby temperatures to 0C

    M302 P1; Allow cold extrudes

    In a terminal:
    T2
    G1 E20

    I don't have access to the web interface, but when running these commands from a terminal hooked up through USB I get an "ok" response. I have also verified that I have the stepper pairs wired appropriately and have verified that the stepper works by plugging it into the Duet and following the same code input but for Tool 1. Does anyone have any suggestions on where I might be going wrong? Thank you in advance for your time!

    Do you have VIN power connected to the DueX5, via its VIN connector? With just the ribbon cable connected, the thermistors will work but not the heaterts, motors or fans.



  • @travis-hainsworth It sounds like you haven't mapped the drives to the extruders with M584. It will probably be easier to help if you can post your entire config.g, along with an explanation of which motors are connect to which drives on both the Duet and Duex 5.



  • Thanks for the replies @dc42 and @deckingman! I have the duex5 powered with 24v from the power supply through the blocks labeled "12v-24v Input" from this overview page. @deckingman you are correct, I have not utilized M584. Why is M584 necessary for using the Duex5 but not necessary for the Duet, and where in config should it go (before M569, before M563, or after M563)? Thanks again for your help!

    EDIT: To fully answer your question @deckingman drive 0 controls the x-axis, drive 1 controls the y-axis, drive 2 controls the z-axis, drive 3 controls the first extruder, drive 4 controls the second extruder, and drive 5 is connected to a stepper motor which raises and lowers the second extruder and is the only one connected to the duex5. I have activated multiple drivers on the duex5 and plugged this stepper into them to ensure that the stepper driver on drive 5 is not faulty. Thanks again for your feedback!

    Check that the firmware knows that the DueX is present, by sending M115 and looking at the returned electronics description.



  • The Duex5 is not being recognized. I have:

    WiFi/Ethernet FIRMWARE_VERSION: 2.0(RTOS)
    ELECTRONICS: Duet WiFi 1.02 or later
    FIRMWARE_DATE: 2018-06-05b3


  • administrators

    It looks like either the ribbon cable is not connected, or the ribbon cable is faulty, or the DueX is faulty (it's possible but unlikely that the Duet is faulty). If you are sure that the ribbon cable is connected correctly, and you are using the ribbon cable that was supplied with the DueX, please ask your supplier to replace the DueX and the cable.



  • Thank you @dc42. I will contact duet3d and try to get a replacement.
