Duet2 Ethernet not responding after reboot/reset



  • Hi there,

    I am new to Duet, but I think I've done some solid troubleshooting on this. I have a Duet2 Ethernet. Everything worked fine, but once I updated the firmware to 2.02a (I only used the board a few times on USB before updating as I just received it and not with the ethernet connected) after a reboot the Ethernet component will just be static.

    This is a Duet2 Ethernet + Duex5

    Green and yellow LED's solid, no blinking. I've done M552 S0 then S1 to reset the port, nothing. I've pulled the cable out and let it sit for a dozen seconds and put it back in, and nothing.

    If I power it off for an extended period (5+ minutes) the port will come back online and work fine until I do anything that causes a reboot of the board. After that point the ethernet port will remain dead.

    This is on 12V and when on USB.

    Do I have a bum Ethernet controller board on this brand new Duet2? Looks like an easy swap to replace if so, but this is frustrating.

    The network config is: ; Network
    M550 P"Joes Printer" ; Set machine name
    M551 P"a password" ; Set password
    M552 P0.0.0.0 S1 ; Enable network and acquire dynamic address via DHCP
    M586 P0 S1 ; Enable HTTP
    M586 P1 S1 ; Enable FTP
    M586 P2 S1 ; Enable Telnet

    The networking setup here is all running managed enterprise hardware, so there should be no issue with that. There are no port errors, the port is just not active when its in this state.

    I would prefer DHCP, but if I need to try static I can do that too.

    Note, when I did the firmware update, I may have accidentally run "M997 S1 " as part of it instead of S0. Not sure if this could be the issue.



  • I've changed it to static IP to see if anything is different, and no it is not.

    Are you providing VIN power, or just USB power?

    If you send M122 from USB when it won't connect, what does the Network section of the diagnostic report show?

    If you don't set a static IP address, does M552 report an assigned IP address, or not?

    But the Green LED is just locked steady with no movement, and I cant access the device. If I power it off for an extended period of 2-5 minutes it will come back and work when I power it up.

    Your M122 report indicates you are only supplying USB power. That may not be sufficient.

  • It does it on 12V VIN as well... but I can connect it to the PSU ,and run the M122 again... I've primarily only used it on VIN supply. Just for this I had to disconnect it to get it over to my PC.



  • @dc42 if I dont set an assigned IP: If it is working, it will report an IP via DHCP, if its not, it wont. It lists no IP or 0.0.0.0

    I suspect a temperature-related fault on the Ethernet board, so I suggest you ask your supplier to swap the Duet for another.



  • Thanks, I've submitted an RMA with the place I bought it.

    I also dont think its temperature related, I can power up the board, and wait 15 seconds ( or how ever long it takes for it to fully boot) , hit the reset button, and the ethernet board is dead then until it powers down for a minute or two



  • Just to follow up, I received my replacement Duet2Ethernet and it works perfect. The last one had issues updating the firmware from the web interface, and the lock up issue with the ethernet in general. The new one is working perfectly as expected.

    Thanks for the troubleshooting assistance.

    Thanks for confirming this. I'm sorry that you received a faulty Duet.
