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.
