Duet will not connect



  • Hi, I am sorry if this is trivial stuff but I am new to this.

    I inherited this printer at work and this morning got back to a mess. It was disconnected from the duet control panel and my slicer program. The TC malfunctioned (I am assuming) and the heating element had a meltdown.
    (The printer also stopped mid print while the Heater stayed on.)

    I am trying to figure out what I need to replace but I am unable to get the duet to connect back to the computer at all.

    I saw that these LEDs can help diagnose what the issue is so here is a picture of what lights up when I turn the machine on. (no green LED and the red LED between the usb and reset button isn't on either.)

    I am sure I am leaving out a lot of needed info, I just don't know what is needed.

    Any help is greatly appreciated.



  • Here are the definitions of the lights, and a checklist of how to proceed:

    green led is for 3.3v and without that you're dead in the water. first remove the SD card and see if it makes a difference, if still dead remove U2 see if you could apply a (current limited external) 3.3v supply (2-300mA should be good) to see if there are other problems.
