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

【Smart Filament Sensor】BIGTREETECH SFS V2.0 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 V2.0 will send error alerts to screen and automatically stop printing to keep you away from filament and electricity waste.
【Sensitive Photoelectric Filament Detector】BTT filament detection module adopts photoelectric sensor whose theoretical detection length can reach up to 2.88mm, much shorter than 7mm of SFS V1.0. Such improvement enables SFS V2.0 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 Feeding】BIGTREETECH smart filament sensor V2.0 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 V2.0 weighs only 36g, greatly reducing inertia added to the direct-drive extruder for higher printing speed and accuracy.
【Easy to Install】Our 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 Compatibility】BIGTREETECH 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 V3.0 / SKR3 / SKR 3 EZ / SKrat / Manta E3EZ / Octopus Pro. And SFS V2.0 is compatible with Klipper, Marlin and RepRap firmwares.

FAQ:

Q: What is a filament extruder?

A: The Lyman filament extruder is a device for making 3-D printer filament suitable for use in 3-D printers like the RepRap . It is named after its developer Hugh Lyman and was the winner of the Desktop Factory Competition.

Q: What is filament current?

A: filament current. in an x-ray machine the strength of the current to the filament is varied by the use of a filament or stepdown transformer.

Q: What is filament light bulb?

A: The filament is the part of the light bulb that produces light. Filaments in incandescent light bulb is made of tungsten . When electrical current goes through it, the filament glows.

Q: What is carbon filament lamp?

A: The carbon filament lamp was the first practical form of incandescent lamp, this material originally being favoured because of the possibility to operate it at temperatures higher than any other electrical conductor that could be produced in filamentary forms at the time.
