BIGTREETECH SFS V2.0 Smart Filament Sensor

The BTT SFS V2.0 represents the pinnacle in filament monitoring technology for 3D printers. It is a highly accurate photoelectric sensor from Bigtreetech, designed to ensure a continuous and trouble-free printing process. This intelligent system is capable of identifying and responding to a wide range of potential issues, from blocked nozzles, filament exhaustion or tangling, to extruder malfunctions, thereby minimizing material waste and saving time.

Innovative Features and LED Status Indicators

Equipped with an LED indicator, the SFS V2.0 provides immediate visual feedback. Flashing blue light indicates smooth printing, while steady red light warns of the need to replenish filament or its breakage. A continuous blue light signals a clogged nozzle or extruder problem. This direct communication enhances efficiency and minimizes the need for constant supervision.

Installation and Compatibility

The sensor can be easily installed thanks to three mounting holes on the back and is compatible with both direct drive and bowden extruders. Its bi-directional feeding ensures the sensor operates correctly regardless of orientation. The SFS V2.0 supports all motherboards with I/O ports, making it an ideal choice for a wide range of 3D printers.
