SFS V2.0 Smart Filament Runout Sensor - Bi-Directional Photoelectric Sensor for 1.75mm Filament

Bi-directional FeedingBIGTREETECH SFS V 2.0 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 DetectionSFS V 2.0 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.; Wide Compatibility, Easy InstallationSupports Bowden and Direct-Drive extruders, with 3 mounting holes for easy mounting to printer using bracket.

Support motherboards with available endstop ports or dedicated filament runout ports, such as BIGTREETECH SKR Mini E3 V 3.0, Manta E3EZ, Manta M8P, Octopus Pro, etc. Please consult our technical support before using the motherboard without filament runout port.; Photoelectric Sensor TechnologySFS V 2.0 adopts photoelectric sensor technology, with theoretical detection length of 2.88 mm, which is more accurate than the 7mm of SFS V 1.0.
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 useInsert filament from the direct quick connector in any direction of smart filament sensor; The red light will i
