Review on BIQU Filament Detection Accessories Transparent by Eric Smithlin

Be careful when installing this sensor. The V (voltage) and S (signal) pins are across from the impact sensor that I replaced. Since there is no information about this on the site, nor a pinout picture, I just used the same cable that was already installed on my printer. When I inserted the thread into the sensor and it worked, the light flashed briefly. and the printer restarted. When I took a closer look at the wire that was included, the V and S wires crossed between the two ends of the cable. So I had to replace the cable to make it work. It's not obvious and there should be documentation that comes with the product or on the listing page to explain the cable and sensor pinouts.
