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. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | BIQU | | Manufacturer | BIQU | | Colour | Black-sfs V2 | | Number of Memory Sticks | 1 | | Item Weight | 36 g | | Package Dimensions | 10.49 x 8.61 x 3.71 cm; 36 g | | Item part number | BIQUSFS2.0 | | Are batteries included? | No | ## Product Details - **Brand:** BIQU - **Material:** Plastic - **Colour:** Black-sfs V2 - **Item Weight:** 36 Grams - **Item Diameter:** 1.75 Millimetres ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/61BbP-ABALL.jpg) ![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 - Image 2](https://m.media-amazon.com/images/I/71DeG-CB3lL.jpg) ![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 - Image 3](https://m.media-amazon.com/images/I/71Mx5WnihYL.jpg) ![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 - Image 4](https://m.media-amazon.com/images/I/71A4QAItBgL.jpg) ![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 - Image 5](https://m.media-amazon.com/images/I/614n0R6enzL.jpg) ## Available Options This product comes in different **Colour** options. ## Questions & Answers **Q: Will this work with Creality 1.1.5 motherboard. If yes, do you have documentation of needed changes to the firmware file?** A: I don't think this will work with the silent mainboard. It doesn't have the necessary connection. You'll save yourself some pain switching to a SKR board. **Q: I have an ender 3 v2. The board is V4.2.2 Will this plug directly into the board and is there a mount available?** A: Yes, **Q: What do i need to do to install on Creality Ender3 Pro** A: I have creality ender pro 3 v2. I needed to swap the white and black wires in the connector that plugs into the sensor. The wire sequence was white black red. I had issues with the signal. I then moved to black white and red and all is good. **Q: Will it work with octoprint?** A: The Smart Filament Sensor plugin works, but the first time I ran and configured it, it didn't detect the movement. After clearing the data for the plugin, and re-starting it. I set my pin (GPIO 11 worked well) in the filament sensor plugin config screen, saved, then ran the test. It detected immediately after this. ## Frequently Bought Together - 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 - BIGTREETECH ADXL345 V2.0 Accelerometer Board Klipper Input Shaping 3D Printer Hotend Parts Sensor Module Support USB Connection for Voron Stealthburner --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/637784333-bigtreetech-smart-filament-detector-v2-0-btt-sfs-sensor-detects](https://www.desertcart.kr/products/637784333-bigtreetech-smart-filament-detector-v2-0-btt-sfs-sensor-detects) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-22*
