Product Introduction
FLY SHT36/42 is a print head tool plate designed by Guangzhou Mellow Electronic Technology Co., Ltd. for 3D printer extruder heads. This tool plate can replace the complex wiring between the motherboard and the print head with four wires, optimizing the layout. SHT36 is suitable for 36 stepper motors, and SHT42 is suitable for 42 stepper motors. It integrates CAN transceiver, USB port, TMC2209 driver, ADXL345 accelerometer, two controllable fans, and other functions. This tool plate is compatible with Klipper firmware.
