1Description
The Mellow Tool-Lite CAN-KF is a compact, high-performance toolhead board designed specifically for Klipper-based 3D printers (Voron, CoreXY, etc.). Powered by an RP2040 MCU and featuring a silent TMC2209 driver, it simplifies your wiring harness significantly—replacing complex cabling with just four wires via CANBus.
Beyond basic control, the board features a Modular Design for Maximum Flexibility. It is engineered to work seamlessly with expansion modules, most notably the EDDY-M. This separate inductive sensor module connects directly to the toolhead, enabling high-speed, non-contact bed mesh scanning without adding bulk to your hotend setup.
