Introduction
Product Overview
FLY SHT36/42 is a nozzle tool board designed by Guangzhou Meilun Electronics Technology Co., Ltd. for 3D printer extruder heads. With this tool board, four wires can replace the complicated wiring between the main board and the print head, optimizing the layout. SHT36 is suitable for 36 stepper motors, and SHT42 is suitable for 42 stepper motors. It integrates a CAN transceiver, USB port, TMC2209 driver, ADXL345 accelerometer, two controllable fans, and other functional components. This tool board is compatible with the Klipper firmware.
