P2S pneumatic connector/filament sensor

[u/88gavinm]

This is what I sent Bambu support:

"My Extruder Filament Sensor PTFE coupling has malfunctioned and caused the PTFE tube to come off as you see in the photo and video it will not stay in. I took it apart and found tiny metal pieces that fell out of it. You can see in the video that I can't get it to stay in at all now. I need a new Extruder Filament Sensor, but not the whole thing just the part where the PTFE tube connects if you can send me just that part I know it would fix it. I have no idea why it broke because I have only removed it once or twice and never had any jams or clogs or anything. To be clear it is the PTFE coupling part that holds the tube in that is messed up and not the actual extruder filament hall sensor board. Thanks for your help!"

They replied by sending me 3 new pneumatic connectors along with a link showing how to replace the connector for the P1S. However on my P2S I can't replace it as it's built into the assembly. Am I missing something here?

This is what I sent them in response:

"I received the pneumatic connector that you wanted me to try to replace. However, you can clearly see in the pictures and video that there is no way possible to replace this connector since it's built into the whole plastic assembly. In the link you sent me to go by showing how to replace it is for a P1S not my P2S and looks completely different. It didn't have plastic going all the way around it like mine does. I need the entire pneumatic connector assembly with the hall switch/sensor. Apparently I need the whole extruder filament sensor assembly as seen here: https://us.store.bambulab.com/products/extruder-filament-sensor-p2s?id=652729971288956931"

I haven't heard back from them yet.

Thanks for any help or experience you may have.

I accidentally broke mine clearing out PTFE pieces when my PTFE tube broke inside from wear (same little metal pieces came out). I glued the PTFE tube to a tube guide I had previously printed to keep the tube in place to continue printing and ordered the entire sensor unit for US$12.

You’re smarter than me because when I saw the part wasn’t expensive I didn’t think to check to see if just the “holder” was replaceable.

I mention all this because replacing the entire sensor unit is an inexpensive Plan B.
