BoxTurtle is exactly what it appears to be — an open source AMS style filament changer for [Klipper](https://klipper3d.org) machines.
|
|
BoxTurtle requires the AFC-Klipper Add-On (found [here](https://github.com/ArmoredTurtle/AFC-Klipper-Add-On)).
|
|
The goal of BoxTurtle is to deliver a user experience as close to an AMS as possible in vanilla Klipper. i.e. an "AMS" for any klipperized printer regardless of form factor but [VORON Design](https://vorondesign.com) printers in particular.

# How it works
|
|
|
|
BoxTurtle is an automated, lane-based filament changing system, also known by some as a "Type B MMU." Each lane is equipped with its own dedicated motor that moves filament to and from the tool head independently, eliminating the need for a selector cart or servos. Synchronization between the lane motor and the tool head occurs when the filament triggers a sensor (such as [FilaTector](https://github.com/ArmoredTurtle/Filatector)) that is located in or near the tool head.
|
|
|
|
To accommodate any differences in rotation distance between the extruder in the tool head and the lane motors, BoxTurtle uses a toolhead buffer, such as the [Belay by Annex Engineering](https://github.com/Annex-Engineering/Belay) or the [TurtleNeck](https://github.com/ArmoredTurtle/TurtleNeck) by ArmoredTurtle. This system is "bufferless," meaning no filament boxes (no spaghetti boxes) are required, similar to the AMS. Each lane features an independent respooler equipped with a brushed motor, which helps rewind the spool and assists the lane motor in feeding the filament smoothly. This prevents issues like spool tangling or "bucking."
|
|
|
|
For precise PWM control of the brushed motors, BoxTurtle relies on a custom MCU, AFC-lite, developed by [Isik's Tech @xbst](https://github.com/xbst/AFC-Lite/) While the system currently supports BTT MMB CAN, this is a temporary solution to facilitate broader testing and will not be a permanent feature.
