BIGTREETECH Smart Filament Runout Sensor V2.0 BTT SFS Filament Detector to Detect Filament Break/Run Out/Jam/Tying for 1.75mm Filament Use with SKR Mini E3 V3.0, SKR 3, Manta E3EZ, Octopus Pro

Smart Filament SensorBIGTREETECH SFS V 2.0 can not only detect filament runout, but also filament breakage, filament clogging, filament tying and even extruder malfunction. Detecting above abnormal extrusion cases, BTT SFS V 2.0 will send error alerts to screen and automatically stop printing to keep you away from filament and electricity waste.
Sensitive Photoelectric Filament DetectorBTT filament detection module adopts photoelectric sensor whose theoretical detection length can reach up to 2.88 mm, much shorter than 7mm of SFS V 1.0. Such improvement enables SFS V 2.0 longer service life and higher precision in filament abnormality detection.
Note: 2.88 mm is the minimum detection length for the sensor to function properly. If false triggers error occurs, try to increase the detection length by 1mm until the problem is resolved.
Bilateral FeedingBIGTREETECH smart filament sensor V 2.0 allows bi-directional feeding, which removes you from hard discrimination of filament inlet and outlet. Such upgrading enables more flexible installation and can maximize space utilization of your 3d printer! SFS V 2.0 weighs only 36g, greatly reducing inertia added to the direct-drive extruder for higher printing speed and accuracy.
Easy to InstallOur filament run out sensor is designed with 3 mounting holes on the back for easy installation onto your 3d printer with only a bracket. The bracket stl file can be downloaded in
BTT github web: bigtreetech/smart-filament-detection-module/tree/master. The filament feeding lever serves for easy flexible filament loading. Please feel free to contact us if you have any doubts.
Wide CompatibilityBIGTREETECH filament jam sensor can be mounted both on bowden extruder and direct drive extruders. It supports any motherboard with available I/O ports(Endstop, filament detection, BL touch, induction sensor, etc), like SKR MINI E3 V 3.0 / SKR3 / SKR 3 EZ / SKrat / Manta E3EZ / Octopus Pro. And SFS V 2.0 is compatible with Klipper, Marlin and RepRap firmwares.
