A Mach3 interface board, also known as a breakout board, is an electronic device that connects the CNC machine to the computer running Mach3 software. Its primary function is to convert the digital signals from the computer into analog signals that control the CNC machine’s motors, spindle, and other components. Mach3 Interface Board Wiring Diagram
