Ok so I am new to 3d printing and got myself the K2, it’s been going great up until yesterday I got an error “feed issue, filament maybe blocked between the cfs hub and extruder filament” when checking I can see filament is in the ptfe tube from the buffer, the cfs is clear of any filament so it looks like it’s come off in the buffer/ptfe tube. I’m guessing it didn’t cut proper?

How do I disconnect the ptfe tube? I’m hesitant to just yank it out. Has anyone else had to deal with this?
