[High Precision] The V2.0 Smart Filament Sensor utilizes high-efficiency photoelectric induction technology for more accurate detection, with a detection length of 2.88mm. Upgraded with a Filament Feeding lever for easy loading of flexible filament. [Real-Time Status Light Indication] This filament runout sensor detects nozzle jams, filament runout, filament tangling, and extruder failures. The V2.0 provides corresponding light indicators for different issues and issues on-screen error alerts in time, automatically pausing printing to save resources. [Upgraded Bidirectional Feeding] The Smart Filament Sensor V2.0 is not limited by filament installation direction, eliminating orientation concerns. Enables quick, easy installation and flexible positioning to maximize space. [Broad Compatibility] The Smart Filament Runout Sensor V2.0 supports Klipper/RRF Firmware, various firmwares, and different screen reminder interfaces. Supports all motherboards with available I/O ports (Endstop filament detection, BLtouch, inductive sensor) such as SKR MINI E3 V3.0, Octopus V1.1/Octopus Pro, SKR V1.4 turbo, SKR 3, SKR Pico, Manta M4P/M5P/M8P motherboards. (Note: Contact our technical support before using a motherboard without a filament runout port). [Easy Installation and Use] The V2.0 Smart Filament Sensor is designed with 3 mounting holes on the back for easy installation on the printer using a bracket. Supports direct drive extruders and Bowden extruders. (For specific wiring and firmware changes, please refer to Github for instructions)
