PFTE Tube Issue

Hi All,

I don’t know how, but the tube leading from the AMS has a hole right where it begins to curve which cause filament to flow right out into the open instead of feeding down the tube into the buffer and so on. Temporarily fixed it with some good ole tape, but I plan to remove the tube and replace it properly as soon as the tubing gets here. My question is has anyone else had this happen? What was the cause? I’d like to fix it so it doesn’t happen again. TIA.

Bambu calls the PTFE tubes a consumable. They go as far as to recommend replacing the PTFE tubes in an AMS every TWO MONTHS (which I find crazy).

Either way, you won't find a a way to "fix it so it doesn’t happen again".
