Hey 3d printing community. Since a few days I proudly own a used ender 3 v3 SE. I repeatedly witnesses the following problem of clogging. Two times printing the same object, after 10-15 minutes it always stops ejecting plastic. Inside the hot end I find then a nail shaped stucked piece of filament, which I can push out from bottom to top after disassembly. Is this due to a wear down of a component or the ominous "heat creep"?

@sakurasubnet my best guess, having had a similar issue with an Ender 5, is that there is a gap between the Bowden tube and the heat break that allows a plug of material to build up there and block things.

@mossyfoot Also thought about that, would explain the shape of the plug 😅 I will try to push it harder in. Thanks for the hint!

@sakurasubnet yeah when I had to rebuild my hot end and replace the heat brake, everything I read said to ensure that the Bowden tube was cut perfectly square and seated firmly in the heat break. It took me several tries.
