BIGTREETECH Smart Filament Sensor SFS V2.0, Runout and Clog Detection, 1.75mm, Klipper and Marlin

Github: Brief Introduction The SFS V2.0 is a smart filament detection module for FDM 3D printers developed by Shenzhen Big Tree Technology Co., Ltd. Feature Highlights The SFS V2.0 is bi-directional, there is no restriction on filament direction, giving the users more flexibility during installation. It 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. Works with Marlin, Klipper, and RRF firmware. Compact, lightweight, and easy to install. Works with Bowden extruders and direct-drive extruders. Support motherboards with available endstop ports or dedicated filament runout ports. Instruction: The filament can be inserted through side of the SFS V2.0. 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. SFS V2.0 Specifications Dimensions: 53.1 x 30.3 x 27.3 mm Weight: 36 g Rated Voltage: 3.3V-5V Working Temperature: -10 to 50 ℃ Working Humidity: 10% to 90% Filament Diameter: 1.75mm Mounting Hole Spacing: 12.4 x 24.7 mm Detection Length: 2.88 mm (theoretical detection length, may need adjustment)
