I just typed up a huge post about this, but I got some 503 error and all of my well written post just disappeared ;_;
So I am just going to summarize real fast ;_;
My print head jams every time. I need to cut the material before each print for it to feed into the head. Prints are now all inconsistent. Using only PLA, a weird blob forms after each print that jams the head. I cannot use the "CHANGE" function to eject without cutting the blob off first. Can anyone spot any obvious issues with these images? Could this just be a problem caused by moisture in the filament? Is my PTFE coupler failing? I have clocked 900 hours of print time so far. 1200 hours of online time. Underextrusion seems to be happening on every print now.
