the old phrase that "its always something simple" holds true to this problem that i adressed a couple days ago. after taking the apron off a couple times thinking that everything fixed itself; i was wrong it didn't fix itself. the simple solution was that i noticed that the 1 inch nut in front of the star wheel had backed off and jammed against the star wheel causing it to jam. all it took was to tighten that nut and everything is fine now. feel kind of stupid; but that's ok i can sleep well tonight
