Unable to Connect Duet Ethernet via Web Interface

  • Duet Ethernet v1.02, Firmware 1.19, initial setup out of the box, powered via usb. Web browser is Firefox 60.0.1 (32-bit)

    When attempting to check access to Duet Web interface get server not found / problem loading page error for duettest.local / IP address respectively.

    Able to connect via YAT. Initial power up was made without ethernet connection. When ethernet cable is connected yellow led on Duet ethernet board is on solid (red diagnostic led on main board is off), green ethernet led flashes intermittently.

    Have tried connecting through Netgear GS308 ethernet switch and directly from PC (Liva X Mini PC Win10). PC successfully connects to network via ethernet port.

    Below is terminal session showing IP address and network running status. When i first connected via usb without the ethernet port connected i did not see the errors associated with running config.g This is my first crack at the Duet so any ideas about how to proceed with troubleshooting will be much appreciated.

    Thank you,

    1. The duettest.local address doesn't work on the Duet Ethernet. You need to enter the IP address into the browser instead.

    2. You are using the config.g file that was on your Duet when we tested it. This sets a static IP address That address may not work with your router. Please change that address in your M552 command in config.g to, also remove the M540 command. Then boot up the Duet, send M552 to find what IP address your router has allocated the Duet, and enter that address into your browser.

  • Thank you, that was the required step. My apologies, i know i came across it whilst perusing the documentation earlier.
