Introduction

The LLL PLUS buffer has upgraded the 28-step motor, suitable for customers who need long-term printing. The volume has increased but is more durable, and it supports the function of detecting material blockage. When inserting materials, it automatically feeds the filament into the extruder!

The LLL PLUS buffer is a 3D printer filament buffer launched by Mellow company, aimed at improving the stability and print quality of 3D printing. The product adopts high-quality materials and advanced design concepts, with features such as wear resistance and high temperature resistance, suitable for various types of 3D printers.

Using the LLL PLUS Buffer

The LLL PLUS filament buffer is a device designed for remote filament feeding of 3D printers, aiming to simplify the loading and unloading operations of filaments. The buffer is equipped with two buttons, used for feeding and retracting respectively, allowing users to perform electric feeding and retraction operations.

Buffer Function:

When the extruder of the 3D printer feeds the filament, if it pulls the filament rack at the remote end, the buffer will detect this action and automatically feed a section of filament towards the hot end. Each time a pulling action occurs, the buffer will repeat this filament feeding operation. This can effectively reduce the pulling force on the filament by the extruder, maintain stable extrusion force, and thus improve the stability of print quality.

Filament Runout Detection Function:

The buffer is equipped with an internal filament runout detector. When it detects that there is no filament in the buffer, it sends a signal to the 3D printer to pause the printing. To use this function, you need to connect the signal pin and modify the configuration of the 3D printer. However, the buffer function can be used directly without modifying the configuration.

Through the above functional design, the LLL filament buffer not only simplifies the filament operation, but also enhances the stability of the 3D printing process and the print quality.

• Please note that the functions can only be used after connecting the filament, otherwise the motor can only be controlled by the button.
