Filament detector kit Creality 3D 2102012333 compatible with Ender-5 S1 K1 Max K1 Sermoon D3 CR-200B Pro

The Creality 3D filament detector kit 2102012333 is a lightweight accessory designed to monitor filament presence during FDM 3D printing. Compatible with a range of Creality models including Ender-5 S1, K1 Max, K1, Sermoon D3 and CR-200B Pro, the detector kit senses filament runout or jams and sends a signal to the printer to pause or stop the print job. At approximately 23 g, the unit adds minimal mass to the moving assembly and integrates with the printer to reduce failed prints caused by filament issues.

Advantages

The filament detector kit provides automated detection of filament absence and basic jam sensing, helping to prevent incomplete prints and material waste. Its low weight reduces impact on print head dynamics, and compatibility with multiple Creality models simplifies installation across supported machines. The device operates passively with the printer firmware to trigger pausing or alerts when filament problems are detected.

Suitable for

• Home and hobbyist FDM printing with Creality Ender-5 S1
• Workflows on Creality K1 and K1 Max for long prints
• Small workshop and classroom 3D printing using Sermoon D3 or CR-200B Pro
• Users aiming to reduce failed prints due to filament runout or jams

Key specifications

• Compatibility: compatible with multiple Creality FDM models (Ender-5 S1, K1 Max, K1, Sermoon D3, CR-200B Pro)
• Weight: approximately 0.023 kg
• Function: detects filament absence and basic filament movement interruptions
• Mounting: designed for integration with supported printer filament paths (requires appropriate mounting point)

How to use

Install the filament detector kit in the filament path according to the printer's instructions or the accessory's mounting provisions. Ensure the detector is positioned so filament passes through the sensing area without excessive bending. Connect the detector to the printer control interface or dedicated connector; verify firmware settings to enable filament runout detection and define the response (pause/stop). Run a test print to confirm the detector triggers and the printer responds as expected before starting longer jobs.

Recommendations

Place the detector in a stable position with minimal filament slack and avoid routing filament through sharp bends near the sensing area. Keep the sensing area free of dust and filament debris, and verify connectors are seated firmly. For long or critical prints, combine the filament detector with preventative measures such as using full spools and monitoring spool mounts to further reduce the risk of interruptions.
