Electric Feeding and Retraction: Equipped with two buttons, the buffer allows users to easily feed or retract filament electrically, streamlining filament handling.Automatic Feeding: The buffer detects when the extruder pulls on the filament and automatically feeds a segment towards the hot end, improving print stability.Filament Break Detection: A built-in sensor monitors the presence of filament and sends a signal to pause the printing process if a break is detected.Enhanced Durability: The Plus version features a more robust stepper motor, increasing the device's longevity.Noise Reduction: Utilizes a silent driver, minimizing operational noise and enhancing user experience.Plus feeding buffer is an advanced device designed specifically for remote filament feeding in 3D printers. It simplifies the loading and unloading process, enhancing the overall stability and quality of 3D prints.Color: As ShownMaterial: plasticPackage Contents:1* Plus feeding bufferOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
