I have some filament blocked in the AMS, near to entry point. I have watched all the vids etc and it looks simple…just press down on the two buttons to release the tube…but no! My buttons do not move at all and tube held fast. Is there a special knack to this? Please help
Sometimes I have to rock the button side to side. Also, push the ptfe tube in before pulling out. Youll see that the fitting bites into the ptfe tubing a bit. Pushing it in first helps release the bite
“Two buttons”? There is a rubber piece with a central cone/hole where the tube inserts, and flat sections on either side. Put your fingers on either side of the cone and push down on the flat part. This will release the tube. It took me a while to get the hang of this.
Thanks for the help. There i literally no movement at all…I cannot push the tube in nor rock the button / flat section at all. It is just solid (and I appreciate I may have confused the issue with my poor description). I have watched all the videos and fairly sure it should be easier than this…
Also, the blockage starts just like 0.5 " into the feed part (not sure what its is called) so maybe that comes out. Does anyone have experience with that?
At this point you’ll likely have to disassemble the AMS and pull out the filaments hub. Dismantling and cleaning the AMS filaments hub | Bambu Lab Wiki
thank you everyone for your help. In the end, I resolved this by unscrewing the two screws, and pulling u the loose spool holder bit until it couldn’t move any more. Another person could then release the tube easily following the vids/instructions on this thread but really needed two people.
BTW very disappointed by customer service who just kept repeating that I just had to press and the tube would release even though I was quite clear that wasn’t working.
I have 2 AMS units. One of them has a very short but noticeable travel when pressing to release the ptfe tube. The second unit however feels like pushing on a brick wall and takes a lot of swearing to get the tube to release.
yes indeed…much swearing at my end too.|t exactly as you describe, like pushing on a brick wall.Still, I know now how to deal with it
With push fit connections like those, they can get difficult to remove if they’ve been fitted for some time. It helps if you push the tube in first while pushing the collar in, then remove the tube while holding the collar in.
What deeply depressingly bad design for this. It could have been made so much easier to get the filament out.
The cables barely reach the micro sockets. 2/10
For clarity, you have to press from inside the ams unit on either side of the tube toward the front of the unit while pulling the tube from the back on the out side of the unit. The ‘inside of ams’ bit of it is what makes the difference.
Course of knowledge is real y’all
I had the same problem, in the process of fixing a “filament won’t retract” problem. There was filament in the tube preventing it from easily disconnecting. In my case, I was able to disconnect the tubes from the AMS hub and access the filament. With the filament no longer under tension, I was able to disconnect the tube as described in the original directions. Hopefully this may help some folks.
easiest way it sto cut the tube and filament where it connects into hub leaving enough tube to pull it out once the tension is released you can then reinsert the cut tube and proceed to clear the filament alot easier
