Filament Out Triggers not Clearing After Reloading Material



  • Sometimes when an extruder runs out of filament, the trigger does not clear after reloading the filament. The machine runs the pause and resume scripts as it should but immediately after resuming, it pauses again due to filament out. Disabling the sensor, resuming, and then reenabling seems to be ok though.

    I have also noticed that if an extruder runs out of filament and DWC disconnects at some point, the Filament out message will reappear every time DWC is reconnected even though I had closed the message window.

    I am running:

    Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
    Firmware Electronics: Duet Ethernet 1.02 or later + DueX5
    Firmware Version: 2.01beta1(RTOS) (2018-06-23b1)
    Web Interface Version: 1.21.2-b2

    @bmmal I assume you are using a simple filament out switch type sensor? What does M119 say about the e0 endstop when its operating normally (filamnt present, filament not present and then what does it say when its has the glitch?

    @chrishamm can you look into the DWC issue reported about filament out message repeating?



  • @t3p3tony

    Yes. M119 does not give any information about the filament switches. Only X, Y, Z, Zprobe.

    With filament present, the machine properties tab does properly indicate that they have not been triggered with "No" though. I can't really check with filament absent right now since the machine is printing but last time I checked the statuses when figuring out how to configure the switches it did work properly.
