Help! DWC Disconnects and Drops after extensive troubleshooting



  • Well...it has officially quit working completely...

    When I try to access the DWC I'm met with a blank white screen that never populates...

    @dc42 would doing a hard firmware reset be a possible solution?

    Does it time out?

    Can you ping it?

    I don't have a filament sensor or panel due fitted.

    It's strange that that is what it's reporting considering the last reset was done by me via M112.

    Please run another M122 report after the network has disconnected, without doing any emergency stops. I want to see if the "Heat task stuck" report is a recurring thing, or if it is a consequence of the emergency stop.



  • @Danal

    It does not timeout, and it still pings without any loss.



  • @dc42

    I was able to get momentarily connected and run M122 right after power-up, here's the result:

  • If it pings, you have a solid network connection and we can quit looking at the basic networking stuff.

    Were it me, I'd rebuild the www directory on the SD card.

    And/or, as a test, you can put your own "test.html" page on the www directory, and test via:

    http://(ip of printer)/test.html

    I've tried rebuilding the www folder already, as well as every other folder. I've tried rolling back to older firmware, and I've tried reloading the most recent full releases. All had the same result, no luck.



  • If it pings, you can get packets to/from. That means WiFi is working, fundamental packet routing, etc. If it does not show a web page, that means something is broken in the HTTP layer, or web server, or content.

    To help decide which try putting:

    <html>
    <head>
    <title>Test Title</title>
    </head>
    <body>
    Test Body
    </body>
    </html> 
    

    In /www/test.html

    Then use a browser to attempt to load http://(ip of printer)/test.html

    What happens?



  • @Danal

    I'll give this a try this evening and report back.

    Please try firmware 2.05RC2 in case this issue is related to a USB output issue in previous releases.



  • @dc42

    Tried upgrading to firmware 2.05RC2. No change.
