Filament Cutter Anti-Tangle Sensor for 3D Printer – Automatic Filament Break Detector with 4 Spare Blades, Ceramic Eyelet & Rubber Ring – Prevents Tangles & Idle Extrusion for 1.75mm Filament

Product Information

About this item

• 【Prevent Filament Tangles & Avoid Idle Extrusion】This filament cutter is designed to automatically cut tangled or knotted filament, preventing idle extrusion and print failures. When filament gets stuck on the spool or forms a knot, the cutter triggers and cuts the filament cleanly – saving your print and your filament. After cutting, the mechanism automatically resets, ready for the next use
• 【Complete Kit – Cutter + 4 Spare Blades + Ceramic Eyelet + Guide Ball + Rubber Ring】This kit includes everything you need: 1 filament cutter, 4 spare blades for long-term use, 1 ceramic eyelet for smooth filament feeding, 1 filament guide ball to reduce friction, and 1 rubber ring for secure installation. No need to buy extra parts – ready to install out of the box
• 【Easy Installation – Wide Compatibility with Automatic Filament Systems】Designed for easy installation on most 3D printers with automatic filament feeding systems. Simply mount the filament break detector between your spool and extruder – no wiring or firmware changes required. Compatible with AMS, CFS, and other multi-spool systems. Note: For printers with built-in tangle detection (such as A1, P2 with buffer, X2D with buffer), please disable the built-in detection feature before using this cutter to avoid conflicts.For AMS installation, please note the cutter may interfere with the lid when using full spools – additional printed components may be required (available on MakerWorld).
• 【Wear-Resistant Ceramic Eyelet – Smooth Feeding & Long Life】The ceramic eyelet provides a durable, low-friction guide for 1.75mm filament, reducing wear on both the filament and the cutter. This ensures consistent feeding and extends the life of your anti-tangle device.
• 【Filament Compatibility & Important Usage Notes】Compatible with most 1.75mm filaments including PLA, PETG, ABS, and ASA. For CF (carbon fiber) and GF (glass fiber) reinforced filaments, cutting is possible but not recommended for continuous use – the high trigger tension may overload the extruder and accelerate blade wear. TPU-85A and highly flexible filaments are not recommended, as the cutting tension can deform the filament before the cut completes.

Product Description

for Bambu Lab ,for creality,for Flashforge,for Anycubic,for Snapmaker Filament Cutter Anti-Tangle Sensor for 3D Printer – Automatic Filament Break Detector with 4 Spare Blades, Ceramic Eyelet & Rubber RingFilament Cutter Anti-Tangle Sensor for 3D Printer – Automatic Filament Break Detector with 4 Spare Blades, Ceramic Eyelet & Rubber Ring The Filament Cutter is a mechanical accessory designed to prevent print failures caused by tangled filament, bent ends, or other obstructions. It automatically cuts the filament when a tangle or knot is detected, stopping idle extrusion and saving your print. Why Choose This Filament Cutter Kit? 【Stop Tangles Before They Ruin Your Print】 – Filament tangles are one of the most common causes of print failures. When the extruder pulls against a tangled spool, the increased tension triggers this anti-tangle sensor. The cutter engages, cleanly severs the filament, and prevents the extruder from grinding against a stuck spool – eliminating the risk of a failed print and wasted material. After cutting, the mechanism automatically resets to its ready position. 【Complete Kit – Everything Included】 – This comprehensive kit includes: Filament Cutter ×1 Spare Blades ×4 – for long-term durability Ceramic Eyelet ×1 – reduces friction and wear Filament Guide Ball ×1 – ensures smooth feeding Rubber Ring ×1 – secures the installation 【Wear-Resistant Design for Long-Term Use】 – The ceramic eyelet provides a durable, low-friction surface that guides 1.75mm filament smoothly into the cutter. This reduces wear on both the filament and the cutting mechanism, ensuring reliable performance over thousands of print hours. 【Easy Installation – No Firmware Required】 – Mount the filament break detector between your spool and extruder using the included rubber ring and guide ball. No soldering, no wiring, no firmware changes – just mechanical simplicity that works with any FDM 3D printer using 1.75mm filament. The cutter automatically resets after each cut, ready for the next tangle. 【Compatibility & Important Usage Notes】 – Compatible with most 1.75mm filaments including PLA, PETG, ABS, ASA, and CF/GF composites. For printers with built-in tangle detection (A1, P2 with buffer, X2D with buffer), please disable the built-in detection before using this cutter to avoid conflicts. TPU-85A and highly flexible filaments are not recommended – the cutting tension may deform the filament. For AMS installation, the cutter may interfere with the lid when using full spools; additional printed components may be needed (available on MakerWorld). What's Included: Filament Cutter ×1 Spare Blades ×4 Ceramic Eyelet ×1 Filament Guide Ball ×1 Rubber Ring ×1 Upgrade your 3D printer with this filament cutter anti-tangle sensor and say goodbye to failed prints caused by tangled filament.
