Filament Detection
Customers have generally positive feedback about the filament detection feature of the BIGTREETECH Smart Filament Sensor V2.0, with some mentioning its ability to detect not just runout but also breakage and clogging, saving potential headaches from failed prints. However, a few customers noted that it required configuration changes on their printer and an additional input for both motion and normal filament sensor use. Some users were disappointed that there is no status light to show filament movement detection.

Basically the sensor wire and positive voltage wire are flipped and this will cause your printer to panic and reboot every time you trip the filament sensor

If your printer is rebooting after installing this and testing the sensor stop screwing with the sensor and unplug it

It has something that works sort of like a fish hook if you pull the wire and don’t press the little barb in you’ll probably break the wire in some way
Posted by a reviewer on Amazon
Just carefully look at the side of the connector realize there is a little needle like barb on the exposed metal part press that little guy in and carefully pull the wire out of the connector
