BIGTREETECH SFS V2.0 Smart Filament Sensor Upgrade Filament

【Bi-directional Feeding】BIGTREETECH SFS V2.0 is bi-directional, there is no restriction on filament direction, giving you guys more flexibility during installation. It suitable for Marlin, Klipper, and RRF firmware.

【Multifunctional Detection】SFS V2.0 detects extrusion errors caused by filament runout, nozzle clogging, filament tying, and extruder trouble. It has two signal outputs and indicator lights to distinguish between clogging or filament runout. Small and lightweight, it will not add too much pressure to the printer's extrusion head.

【Photoelectric Sensor Technology】SFS V2.0 adopts photoelectric sensor technology, with theoretical detection length of 2.88mm, which is more accurate than the 7mm of SFS V1.0. Please Note: 2.88 mm is the minimum detection length required for the sensor to function properly. If you encounter problem of false triggers, try increasing the detection length by 1mm increments until the problem is resolved.

【Instructions for use】Insert filament from the direct quick connector in any direction of smart filament sensor; The red light will illuminate when there is no filament in the module. The blue light will flash when the extrusion is normal. The blue light will stay on or off when there is no extrusion.
