This is what it looks like when your extruder jams and forces filament out the side on a MK4 extruder.
I pulled out the filament and removed the clogged plastic. It works fine now.

Edit. Forgot image

Any thoughts?

The only time I ever ran into the skipping/stripping was when there was a partial clog and it wasn't allowing the plastic to exit fast enough, causing back pressure and only allowing it to feed if I pushed it by hand harder than heck.

There may be a slight difference from machine to machine though, but I would make sure not to tighten it so much as to deform the filament, it should just leave a nice line of 'teeth' marks.

I tighten mine so about 3 threads are sticking out past the nut. If the spring is very tight, then the failure mode becomes the extruder skipping steps. If this happens, there's a clog/jam.

I have been having an issue where about 1-2 hours into the print I go to check on it and the extruder gear has eaten part way through the filament and stopped pushing it into the heater barrel. My guess is that my spring is either just slightly too tight or not tight enough and ass the whole thing heats up thermal expansion pushes it to the point of not working. Any other possible causes and what should I do to fix it.
