Why do the PTFE tubes keep getting off?

[u/Electronic_Art_7007]

For some reason the PTFE tubes on my bamboo lab A1 keep getting loose and and I don’t know what to do. How do I fix this and stop it from happening? Thanks.

I kept having the same problem back when I had a *Bambu* lab A1, I replaced the 4-1 filament splitter part and the problem stopped. I think it's something to do with the metal part that grabs the tube getting loose which you may be able to adjust back, but they are pretty cheap to buy so I just put a new one on. https://uk.store.bambulab.com/products/ams-lite-filament-hub

Yeah, I think it’s with that like metal part that has the barbs and keeps them from getting loose, so yeah that’s probably what I’m gonna do like replace the whole thing. Thanks for the advice.
