Here we go again, yet another k2 issue. Now it just clicks as the video will show while it attempts to push filament through. Brand new gears in there by the way, just to be sure due to a previous issue with clogs and feeding. I mean…these machines are absolute nightmares.
I have had this twice.
Usually means a blocked pathway (not necessarily extruder). Most likely the nozzle.
Heat nozzle up and take it off and pull out the filament that is protruding at extruder end.
When you put in back in and extrude the extruder should work. If it then stops it is the lower part of the nozzle blocked.
Check hot end not loose, 2 screws above heat sock. If it is tighten and try again. If it fails then swap nozzles and it likely to be ok.
Thanks a lot. I had figured it was a clog, and tried unclogging it but when I heated the nozzle up to 320C, it just slowly oozed out, barely moved (still stuck in there). I tried using the poke stick, and the filament inside just fused to the stick. When it did ooze out, it was a black char color almost as if it were just burnt up plastic. I have no clue why, but this was overture transparent filament. I just swapped nozzles in the end.
