## Long description

The Filament Sensor for 3D Printer Prusa MINI+ by Prusa is a dedicated filament detection unit designed to integrate with the Prusa MINI+ extrusion system. It monitors filament presence and movement to detect runouts and feed interruptions, allowing the printer to pause automatically when a problem is identified. The sensor helps maintain print continuity and reduce failed prints and material waste during long or unattended jobs.
Advantages
This filament sensor provides reliable detection of filament presence and motion compatible with the Prusa MINI+ hardware. It enables automatic pause-on-runout and pause-on-jam behavior to protect ongoing prints. The unit is designed to integrate seamlessly with the printer’s firmware and extrusion pathway, offering stable mechanical and electrical connection for consistent performance.
Suitable for
 Owners of Prusa MINI+ printers who want runout and jam detection
 Long-duration or unattended printing tasks where print continuity is critical
 Users aiming to reduce filament waste caused by unnoticed runouts or feed jams
Key specifications
 Compatibility: Designed for Prusa MINI+ extrusion system
 Function: Detects filament presence and movement; triggers printer pause on runout or feed interruption
 Integration: Electrical and mechanical interface intended for direct integration with the printer’s filament path and firmware
 Operation: Passive detection of filament motion and presence suitable for common 1.75 mm filaments used with the Prusa MINI+
 Mounting: Designed to fit the original Prusa MINI+ mounting points and filament route
How to use
Install the filament sensor in place of the standard filament path component according to Prusa MINI+ assembly instructions. Connect the sensor to the printer’s designated header and verify firmware support or updates if required. After installation, load filament and perform a controlled test print or filament feed to confirm the sensor detects motion and presence correctly and that the printer pauses as expected on runout or blockage.
Usage recommendations
Use the sensor with standard 1.75 mm filaments recommended for the Prusa MINI+. Periodically inspect the sensor and filament path for dust, debris or wear and keep firmware up to date to ensure proper communication between sensor and printer. For unattended long prints, pair the sensor with reliable spool handling and a stable power supply to minimize external causes of feed interruptions.
