If itโs showing you the cutter is jammed or check wire connection this is it
If u know u know , I was cleaning out a recent new filament I had gotten and it had gotten barely stuck and well I had overly done it and made the smaller slit on my connection and it kept saying cutter was Jammed even though it wasnโt and to check the connection, clearly it was the problem, great for bamboo and worked on the first try, it literally takes 6 acres that are right away obvious and bang back to work

Back up and running
I tore the original ribbon cable on my P1S when cleaning the extruder. This got me back up and running within a few days when Bambu is out of stock. So far I've only done a couple short prints. It's definitely not the exact Bambu part, like some reviews have suggested. There are clear differences.

Probably OE but not labeled as.
Donโt believe the other reviewers. I have a P1S and needed just the cable but this one came with the board. It also came sealed in anti static bag then in a plastic case that was taped shut. This is by far the best packaging Iโve ever seen. For the product, the board itself just doesnโt have the wording the original Bambu did but itโs just writing for the computers to pick up during manufacturing. Since this is not made by Bambu it doesnโt have that writing It absolutely fit flawlessly with a slightly longer cable which at first i didnโt like but now appreciate some slack just in case i have to take it off again for a jam or something. Buy with confidence. This sucker was A1

Third Party, not Bambu
I bought this as a spare part for my Bambu P1S. Although it is a third party part and not made by Bambu it looks identical to the original and other reviewers state it works just fine. It does come in a nice slim plastic box.

Perfect fit
I kept getting an error that said the cutter was jammed and it wouldn't print. After exhausting all my options I figured it must be the sensor. Sure enough this fixed my problem right away. Perfect for even comes with some 3m adhesive to keep it tight to the housing. It was a perfect fit and now I'm back to printing. Can't even tell the difference between this and the OEM part. Thanks !!

Works just like the original
I never know what to expect when ordering these non-OEM pieces online but I'm pleasantly surprised by this one. It looks just like the original and was easy to install. The printer was back up and running like new without any issues after switching them out. Everything prints great and you would never know that this wasn't an original part.
