I'm unsure if its the feeder that is jammed or if the filament is somehow clogged in the tube.
I've been printing OK with pla for a couple of weeks. I took the plunge with semiflex ( which is the red filament in the pix ). I had difficulty getting and ended up selecting the change material option which wound the material back along the tube.
I think during this feeder pulling back the filament, some semiflex was still hot, and some stuck in the tube. And so when I fed the filament in again it got jammed at this point.
I'm wondering if the filament is jammed in the tube or if the feeder itself is jammed.
I've lifted the feeder lever at the side ( the one you lift when you feed in new material ) and tried to pull the filament out but its jammed solid. I think the semiflex would break before moving.
Any ideas ?
