Filament binding

Is anybody having an issue with filament binding in the filament guide? I’ve had this issues more than a few times. Any help or guidance would be great. Thank you in advance

If you mean the long guide tube, it might be debris that’s built up in that.

Occasionally when changing filament I’ll use the new filament to push a Q-tip head through the guide tube ahead of the filament. Just the fiber tip and maybe 5mm or so of the body behind it. The first time I thought to try that I was surprised at all of the black gunk that came out on the Q-tip at the end.
