Description
The Fly Micro 4 is a compact 3D printer motherboard with four 2209 drivers supporting sensorless homing. It includes heating and temperature measurements for both the print head and the heated bed. It can use BLTouch and metal proximity switches for automatic bed levelling. With a CAN interface, it can connect to CAN tool boards. The four end-stop connections fulfil the basic requirements for a 3D printer, making it suitable for DIY projects or converting existing machines.
