Pulling it all off will destroy your PLA. When it gets bent, it will soon after get brittle like spaghetti.
Filament can actually ot get tangled unless someone let go of the end. The way it was rolled on means that it can only roll off cleanly, unless you (or someone in the factory) let go of the end. The end is always supposed to be in your hand, in the printer or attached to the spool.
This also means the tangle is most probably ot far on the spool. So to fix it, pull the filament tight and hold it with you hands (maybe get someone to help you) so that all the windings are completely stationary. Then roll the filament off until it gets stuck. Pull it through the tangle, and either print the rolled-off part directly or cut it off.
OK, so no to pulling it all off.
I'll give this a try, but let's say I put the filament in the printer cleanly -- ~~the filament won't be tight for long as it gets pulled into the printer, so what's to keep it from jamming itself up again?~~
UPDATE: I really need to learn to try things before I start complaining they won't work.
I followed your advice -- as I was tightening up the windings, it became clear that the lead winding was under the next one. I know I wasn't the most careful when I initially loaded it, so you're diagnosis was probably correct.
So I pulled the tangle out, cut off the damaged section of PLA, and more carefully reloaded the filament this time. It seems better now -- the filament is feeding better now. Time will tell -- I'll post an update when this print either completes or fails.
Happy, that it worked!
Watch out, could be that you ave a second tangle, though it's unlikely.
Regarding being tangled from the factory: No matter how messy the winding, if it was rolled on without any tangles (and you can't roll it on with tangles), it can also roll off without tangles.
So the only way it can get tangled is due to a loose ending. Sure, they could have let the ending slip in the factory, but that would be a terrible fail for a factory. That usually doesn't happen.
