Product details
Description
The BIGTREETECH SFS V2.0 Smart Filament Sensor is an advanced accessory engineered to protect your 3D printing projects from unexpected failures. Utilizing high precision photoelectric induction technology, this intelligent module monitors your 1.75 millimeter filament in real time to detect runouts, breaks, tangles, clogs, and nozzle jams instantly.
Designed for versatility, it features bi-directional feeding capability, allowing you to load filament from either side without configuration restrictions during setup. Dual signal outputs accurately distinguish between a complete filament runout and a mechanical jam, giving your printer the reliability it needs for long, unattended prints.
Fully compatible with Klipper, Marlin, and RepRapFirmware platforms, this sensor seamlessly integrates with popular control boards such as the SKR Mini E3 and Octopus. Whether you are upgrading an Ender series machine or building a custom FDM setup, this sensor ensures uninterrupted workflow and reduces wasted filament.
How to use
- Mount the BIGTREETECH SFS V2.0 sensor securely along your filament path before the extruder.
- Connect the wiring harness to your 3D printer motherboard supporting 3.3V to 5V power input and the appropriate signal pins.
- Update your printer firmware configuration for Marlin, Klipper, or RRF to enable runout and encoder monitoring, then thread your 1.75 mm filament through the bi-directional intake.

FAQs
Does the Ender 3 V2 have a filament runout sensor?
Standard Ender 3 V2 models do not come with a built-in filament runout sensor out of the box. Adding an intelligent upgrade like the BIGTREETECH SFS V2.0 provides advanced detection for runouts, breaks, and jams.
What firmware does the BIGTREETECH SFS V2.0 support?
This smart filament sensor supports Klipper, Marlin, and RepRapFirmware platforms. It integrates smoothly with popular control boards including the SKR MINI E3 and Octopus.
How does the sensor detect filament clogs versus runouts?
The unit combines a precision photoelectric sensor with a rotating encoder wheel and pulley system. This dual-signal architecture allows the system to differentiate between a stopped spool and a physical jam in the extruder.
