Two possible causes for this that I know of.
1. Pourly would filament from supplier (pre tangled and crossed over on reel). Fix = Get new supplier
2. Spool turns too easy, people use to think the spool would work better on bearings, turns out this is a bad thing, there should be a bit of friction between the spool and spool holder so it takes a little bit of effort to pull the filament off. If you are using any kind of bearing system spool holder get rid of it.
