Topic: Extruder filament feed wheel.

Hi all, I am having problems printing, more and more actually. My hot end was laying down normal, then thin strands of ABS, as if it was clogging and stringing, then I noticed that the feed wheel (that pulls the filament) has been grinding my filament and has a ton of ABS shavings coating it. Does this indicate that the spring tensioner is too tight or too loose?
I am thinking it is too loose, hence it slipping by and grinding off praticles, making the problem worse.
Any thoughts?

So it is too tight? If I loosen it, is there any secret to determining how much is enough, or just experiment with it?

As a side note, it is still printing, right now as a matter of fact. Just the raft and sometimes the first layers are stringing and pulling. Often times, midway through the print it pulls the item off the tape (heated bed) and ruins the entire job. Very frustrating.

Maybe it is overextrusion or hotend low temperature?
