Small with Huge Power, Exquisite shape and precise structure High Torque Extrusion, Force up to 80N: The gear transmission features a 6.25:1 reduction ratio, perfectly matched with the motor. This design delivers an extrusion force of up to 80N (depending on the filament), ensuring more precise control over feeding and retrac-tion volumes Dual Gear Feeding, More Stable Printing: High-hardness, wear- dual gears durability against repeated feeding and retraction, as well as the abrasive nature of fiber-reinforced filaments, sianificantly extending the lifespan. Built-in Filament Break Sensor: The built-in "zero-distance" filament break detection mechanism in the extruder accurately identifies feeding interruptions and promptly alerts the user. This helps prevent print failures and ensures every spool of filament isused to its fullest.<br><br>K2 Plus Extruder Kit Small But Exquisite,With Strong Capability Compact and Dual gears for smooth feeding Built-in filament break sensor Product size:47 x 40 x 23.5mm Drive:Dual gear drive Maximum force:80N (depending on consumables) Measuring ratio:6.25:1 Supported consumable diameter:1.75+0.05mm Vehicle accessories:K2 Plus Breakthrough, Excellent Manufacturing High torque: 6.25:1 gearreduction ratio Dual gears for smooth feeding: high hardness and wear- gears Break detection: Built-in filament break sensor Color: Black Material: plastic<br><br>Package Contents: 1 * Extruder Kit<br><br>Only the above package content, other products are not included.
