MACH3 CNC 5-axis interface board with optocoupler, controls up to 5 stepper motors, MACH3/EMC2

The MACH3 CNC 5-axis interface board with optocoupler and USB cable is an essential module for controlling up to five stepper motors from a computer using CNC control software such as MACH3 or LinuxCNC (EMC2). It is compatible with most 2-phase drivers on the market and provides complete signal isolation through its optocouplers, ensuring the safety of your computer and the stability of your system.

This board is powered via USB and accepts a wide voltage range (12-24V) with reverse polarity protection. It offers multiple inputs for managing limit switches, emergency stops, tool alignment, and other critical functions. An output relay allows direct control of peripherals such as the spindle, water or air pump, while a 0-10V analog output makes it easy to manage spindle speed via a frequency inverter.

Fields of application:

• CNC machining (milling machines, laser cutters, CNC routers)
• Rapid prototyping
• PCB manufacturing
• Light industrial automation

Example projects:

• Building a 3 or 5-axis CNC milling machine for custom mechanical parts fabrication
• Creating a CNC laser engraver for cutting and engraving various materials (wood, plastic, acrylic)
• Developing a plasma cutting machine for artisanal sheet metal work
• Automating a prototyping workshop for PCB manufacturing
