Duet Ethernet Networking

  • Hello,

    I was told that this was the place to go to see if you fine gentlemen\gentle-ladies could help me.

    I just bought an Duet Ethernet

    And it turns out that the Ethernet card on this board is no fictional. I have ran test after test with good known cables I even reinstalled the firmware from starch. I know sometimes these things happen is there additional testing I can do?

    Thanks in advanced.

    Do you have command M552 S1 (without a semicolon at the start) in your config.g file? That command enables networking.

  • Yes here is my config.g, do I have it right or am I missing something? Thanks again šŸ˜ƒ

  • How do you have the Duet connected to your network? (cable direct to computer, cable to a switch, cable to a router, etc)

    What is your IP/Gateway/Netmask from your computer's ethernet connection? (copy/paste ipconfig output here)

    How have you attempted to connect to your Duet from your computer? (What steps, what IP address are you using, how did you determine that IP address)

  • Cable to switch.

    Nothing crazy just a network and a (netmask), I was going to set it to DHCP, but does it need to be staticed out?

    I am connecting it to the network via 24p gigabit switch using multiple cables and ports, other systems on this switch works just fine in the same ports.

  • Shouldn't need to be static out but try P0.0.0.0 in the M552 line

  • administrators

    If you send M552 with no parameters from your PC via USB, or from PanelDue if you have one, what does it report?

  • This is what I get.

    Network is enabled, configured IP address:, actual IP address:

    But still no link lights

  • administrators

    If you get no link lights at all then can you check plugging it into the network port of your laptop (quick and easy way to check if a crossover is required for that switch, unlikely but possible). If you still get no link lights then contact your supplier for a replacement under warranty.

  • How long does it take the network stack to startup?

  • administrators

    I have not timed it but on the Ethernet its <1s from memory (I don't have an Ethernet board setup right now for test).

  • Is there anything else I could test before sending it back?

  • administrators

    If the link lights don't come on and the Duet reports that networking is enabled, then either the cable is bad, the port on the switch is bad, or the network adapter on the Duet is bad. So try a different cable and port, and if it still doesn't work, return the Duet.

  • I have tried 4 different cables and 2 different switches. Thanks for the help guys I will contact my distributor for a replacement.

  • is there something that we should check if DWC takes a long time to connect? I'm set up board>router>PC once up everything works lightening fast (well a couple of issues not withstanding)
