Intermittent underextrusion

  • I have an Ender 3 and after printing a few things in PETG, I have tried to print in PLA with no success. I have:

    cleaned nozzles

    replaced nozzles

    increased temps

    decreased temps

    rebuilt hot end

    added direct extruder

    changed PTFE tubes

    leveled bed

    releveled bed

    said bad words

    threatened the printer with unpleasantness


    more bad words

    apologized to printer

    begged it to work

    eSun cleaning filament

    It seems to start fine (sometimes) and then I'll check after a few minutes and it is doing that clicking thing where the filament is not feeding, or on the rare occasion that it does finish a print, it is spongy and crap.
