5-axis CNC breakout interface board works with MACH3 software to convert computer LPT signals into pulse and direction signals for stepper motor drivers. Optocoupler isolation separates the computer side from the high-noise CNC power circuit, effectively preventing static shock and electrical damage to your PC. It provides relay contact output for spindle switching and 0-10V isolated analog output to drive inverters for variable spindle speed. Terminal blocks are clearly labeled for X/Y/Z/A/B axis, limit, E-stop and probe connections. It supports both common anode and common cathode stepper drivers. Ideal for DIY CNC engravers, milling machines, plasma cutters and router projects. USB port only supplies power for the onboard circuit.
