  • This means in first place that the server is not reachable from your browser. If it is still printing it runs but network is not reachable. Can happen with pi with wifi connection if ti switches e.g. to AP mode (check if the AP point appears in wifi router list on your mobile).

    If the server stopped running, go to logs in printer menu when it comes back and check server.log and syslog at the time when it happened. There should be more information. Important part is to know time where to look as the logs can be quite log.
  • Thanks for your input, same user here.
    This is the log:



    Any idea? Running a 7 printers server on a win pc . USB ports are switch powered.  
    Looks to me like suddenly the server couldnt see the printers anymore.
    Thanks !

  • This error shows clearly that the printers initialised a Firmware Stop / kill due to a security function buildin. Are your temperatures instable? Maybe you got a thermal runaway.

    However this is not the server log, this is the printer gcode log. you can find the server log if you go in the context menu of the printer and select logs  
  • Ok yes, there i found the lines "closing websocket for missing ping", and then "reading serial connection failed" . So i guess the USB failed in some way
  • It is running quite warm in fact

    Could you send us the section with the error messages?

    sure. Running on win 10, free version, not connected to internet.

    This is linux having serial driver stopped and hence we can not read from it any more. Since it affects several printers at once it is linux disconnecting usb port/hub. Check /var/log/syslog at same timestamp and you will see the reason why linux did it.
