Upgrade your Klipper-powered 3D printer with the Box Turtle Automated Filament Changer Kit, designed by Armored Turtle and manufactured in collaboration with LDO Motors. Box Turtle is an open-source, lane-based automated material system (AMS) created to bring seamless multi-color and multi-material printing capabilities to Voron Design printers and custom Klipper machines without requiring messy filament buffer boxes. Built with independent active respoolers, premium LDO motors, and dedicated lane extrusion, Box Turtle provides reliable, synchronized multi-material switching directly through the AFC-Klipper add-on.
Key Features
Bonus Injection-Molded Trays: Includes custom injection-molded trays for improved durability and smooth spool rotation out of the box.
Lane-Based Drive System: Dedicated individual motors per filament lane move material directly to and from the toolhead, eliminating complex selector carts and servos.
Premium LDO Motors & Hardware: Powered by high-torque LDO pancake stepper motors and built with premium anodized aluminum extrusions, LDO rubber tires, and rubber feet.
Custom AFC-Lite Control Board: Features the custom AFC-Lite MCU supporting both USB and CAN bus communication protocols for precise motor and respooler PWM control.
Active Respooler System: Independent brushed motor respoolers dynamically rewind spools and assist feeding to prevent filament slack, tangling, or "bucking."
Included Functional Components: Comes complete with pre-crimped internal wiring harnesses, Omron D2HW filament sensors, Filametrix cutter hardware kit, TurtleNeck buffer hardware kit, and durable MJF PA12 nylon gears.
Printed Parts Not Included: This hardware kit contains all required Bill of Materials (BOM) components except structural 3D-printed parts. Print files are freely available on the official Armored Turtle GitHub repository.
System Requirements: Requires a Klipper-based 3D printer running the AFC-Klipper Add-On software alongside a toolhead filament sensor (e.g., FilaTector) and buffer system.
Machine Interconnect Cable: Includes all internal wiring; the main umbilical cable running between the Box Turtle unit and your main printer electronics must be provided separately based on your machine's layout.
