I think I used wire cutters to cut the tubing. But you would like to end up with a clean end to re-insert in the coupler.
Cannot include a link here. Please search for " Tweezer - Set of 4".
Wow! I had no idea this is such a common issue. I too had the same problem, but thanks to all you guys, it’s solved. Thank you, thank you!

me acaba de suceder se atasco justo donde termina el tubo ptfe, para solucionarlo calente una pieza metalica de menor diametro y con cuidado lo empuje desde donde tenia acceso y afortunadamente salio

I’ve had a feed issue inside of the extruder itself. Nowhere in the PTFE tube chain could I get one to release. This was due to the filament being locked up as someone else pointed out. I ended up removing the hotend, then the extruder from the gantry. Unscrewed the little sensor connected to the clear bit of plastic on the extruder. Then I unscrewed the little bit of clear plastic from the extruder. This gave me access to just enough filament to be able to snip it. From there I was able to resolve the issue.
PSA!!! The AMS does not like the older PolyAlchemy Elixer Silk PLA, the feed gears just chew up the filament. So do not attempt a multi-color print with the stuff. You can do a single color print well enough as it doesn’t constantly feed it in and out. Though this probably doesn’t matter that much as it is discontinued filament.
The printable tool made it so easy - thank you
THANKS! That worked - and I’m so glad I found this thread. Push the lever down, push the PTFE down, hold the lever down, pull the PTFE up. It went smooth and extremely easy. Barely an inconvenience!

Couldn’t get the PTFE tube out of the tool head, but I could see the end of the filament was only about 6 inches from the end of the tube (once removed from the rubber sleeve near the back top of the machine). I had just got the Sunlu Filament connector so I added the plastic connector (halfway) to the end of some old filament and pushed the open end of the connector into the PTFE tube until it grabbed the “stuck” filament… Pulled it out too easy!!!
Good recommendation BD489. My jam is aero-PLA, (from 3DLabPrint)
I got an earlier jam with it, but was able to clear it. Second time no joy. I took extruder assembly out, was able to cut the filament just above the hot-end, but cannot extract filament back to spool - feeder mechanisms must lock one way when printer is powered down.
Of course ptfe tube is stuck in extruder assembly because of the filament. So I’m going to do what you did. As to the AeroPLA, I have a MakerGear M2 which has printed dozens of parts with this filament without any problem so I guess I won’t use it in the X1C anymore. It looks like under some condition it swells inside the extruder assembly to jam.
I hope that a BambuLab engineer reads what is posted here. I find the X1C an excellent machine to use, but maintenance is not easy. I should have been able to cut the filament at the hot-end, and rewind it out of the ptfe tube which would then have been easy to disconnect. That might be a firmware maintenance function which could be added in an update. Or otherwise make it possible to back the filament out of the extruder assembly manually.
I do think the video guides here are excellent. But you also need one on rebuilding the hot end which shows the entire process including how to get the sock off.
This worked. Thanks! I had to look around for a while before finding this solution. Really appreciate not having to fully disassemble everything.
