Duet Ethernet Connection Dropping



  • Over the last couple of weeks I have been having difficulty with my Duet Ethernet dropping connection. I have frequently updated the firmware to development and release versions. I just updated to the newest V2 release this morning, including the appropriate DWC. Below is a diagnostic output. I have tried both Chrome and Edge with the same problem. Oddly, I am able to upload large files from the Cura addon but not able to complete uploading of any files through DWC. I have not seen any packet loss when trying to ping the printer either. I have a ticket in with the IT department here to see if there are any network related issues as well but thought I would see if there is anything obvious here too.

    I can establish a connection for a short period of time (maybe 10 seconds) and then it drops, reconnects, and repeats.

  • I just noticed that I often get an invalid password message when it disconnects. I disabled the password and this has stopped. Now, I am getting "Network error, failed to get file list." Or just "Connection Interrupted Network Erro."
