This is what I have been doing.
Agree with @PaulT that the Feeder Button will probably fix your problem.
That’s what I think was the issue on mine as well. That the filament was coming in at too hard of an angle and was digging into the funnel and catching on it. The Feeder Button along with PTEF tubing keep it going in nice and straight.
Originally I thought the whole funnels were bad and ordered 4 new ones, but several others in this thread have had success with a Feeder Button fixing the issue so I’m hoping that’s all it is.
@Jrock also had this problem and ordered new funnels, but the Feeder Button fixed the issue before his arrived. He reported that his new funnels appear to be made of different plastic, so we’re hoping this isn’t such an issue on the AMS and new funnels moving forward. I’d still recommend Feeder Buttons to anyone, even if you aren’t having the issue yet, as the funnels are a wear and tear item.
