Any idea what this small plastic adhesive square came from?
I found it in the poop bin.

I think that is from the top of the poop shoot, I know I can see a square about that size at the top inside of the shoot on my X1CC

Yes it sits at the top of the poop chute.
It is visible at the second picture of Replacing The Nozzle Wiper | Bambu Lab Wiki
No idea what the function of it is :slight_smile:

I think it’s to help detect when the shoot is blocked, I know I can see red light flashing in the shoot from time to time.

Thanks all. It has an adhesive back, but I will add a little contact adhesive when I put it back…
