The MACH3 5 Axis CNC Machine Controller Board is a reliable and efficient interface board designed for CNC machines requiring up to 5 stepper motor driver control. Built to work seamlessly with MACH3 software, this breakout board connects via a standard parallel (LPT) port and provides stable, isolated signal handling for safe and precise machine operation. Featuring flexible 12–24V input power support, durable PCB design, and secure ARK connectors, it is an ideal choice for CNC DIY builders, upgrades, and industrial automation setups.

This breakout board is not a motor driver. It functions as an LPT interface and must be used with external stepper motor drivers to control motors. The USB port provides power only for the board, not for data communication.

Features:

• Full MACH3 support for CNC machine operation

• Parallel port (LPT) communication for stable data transfer

• USB-powered board (power only, not data communication)

• Supports up to 5 independent stepper motor drivers

• ARK screw terminals and 4-pin driver connectors for quick wiring

• 12–24V wide-range input power compatibility

• Anti-reverse protection to prevent wiring damage

• Complete galvanic isolation to protect PC and peripherals

• Common cathode or common anode control supported

• 0–10V PWM analog spindle control output

• Designed for reliable, noise-free CNC system integration

• Compact and strong PCB construction for long-term use

Specifications:

• Supported Software: MACH3

• Communication Interface: LPT / Parallel Port

• Power Input: 12–24V DC

• USB: Power supply only (cable included)

• Stepper Motor Control: Up to 5 axes (drivers required)

• Output: 0–10V PWM

• Isolation: Full galvanic isolation of input signals

• Safety: Anti-reverse power protection

• PCB Dimensions: 90 × 70 × 18 mm

• Connectors: ARK screw terminals, 4-pin driver connectors

How to Use:

• Connect the board to your computer via the LPT parallel port

• Use the USB cable to supply power to the controller board

• Connect external stepper motor drivers via 4-pin connectors

• Supply 12–24V DC power for end-stop and limit switches

• Configure MACH3 software for 5-axis control as required

• Use the 0–10V PWM output to control spindle speed via a VFD (if needed)

• Ensure all wiring is correct before powering the CNC system

Suitable Applications:

• DIY CNC machine builds

• CNC router, CNC engraver, CNC milling machine upgrades

• Industrial automation training systems

• Multi-axis machining projects

• MACH3-based motion control systems

• Stepper motor control for CNC retrofits

Installation Instructions:

• Mount the breakout board securely in an enclosure or control cabinet

• Connect LPT cable to PC parallel port

• Power the board via USB

• Provide 12–24V DC supply for limit and end-stop switches

• Connect each axis driver to the corresponding AXIS output header

• Connect PWM output to spindle/VFD if required

• Double-check wiring, then configure MACH3 pin settings

Safety Precautions:

• Do not connect stepper motors directly to the board

• Ensure proper grounding to avoid electrical noise issues

• Use only stable 12–24V DC regulated power supplies

• Disconnect power before changing wiring

• Keep board away from moisture, metal debris, or conductive dust

Package Includes:

• 1 x MACH3 5 Axis CNC Machine Controller Board

• 1 x USB Power Cable
