5-Axis CNC Breakout Board Stepper Controller | Mach3 Compatible
5-Axis CNC Interface Breakout Board – Mach3 Compatible Stepper Motor Controller
Take full command of your CNC machine with this professional-grade 5-Axis CNC Breakout Board. Designed for seamless compatibility with Mach3 and any parallel-port-supported CNC software, this interface adapter delivers reliable, noise-free signal isolation between your PC and your stepper motor drivers. Whether you're running a DIY router, plasma cutter, or milling machine, this board gives you clean control over up to 5 stepper motor axes — all in one compact, optocoupler-isolated package.
Made in Mainland China.
Key Features
- Mach3 & Parallel Port Compatible: Fully supports Mach3 and other CNC software with parallel port control for broad compatibility.
- Optocoupler Isolation on All Inputs: Every input signal is optically isolated, protecting your computer from electrical noise, surges, and short circuits — ideal for connecting emergency stops, tool setters, and limit switches.
- Isolated USB Power Supply: The USB power circuit is completely separated from the peripheral power supply, keeping your computer safe at all times.
- Wide Voltage Peripheral Input (12–24V): Flexible power input range with built-in reverse-connection protection for worry-free installation.
- 5-Axis Stepper Motor Control: All 17 parallel ports are fully open and accessible, supporting up to 5-axis stepper motor drivers equipped with optocoupler inputs.
- Relay Spindle On/Off Output: One relay output port (P17) lets you switch your spindle on and off directly from your CNC software.
- 0–10V Analog Voltage Output: Optocoupler-isolated analog output (P1 port) interfaces with VFDs (Variable Frequency Drives) for precise spindle speed control.
- PWM Output: P1 also functions as a PWM output to drive spindle speed governors with optocoupler inputs.

Frequently Asked Questions
Q: Is this 5-axis CNC breakout board compatible with Mach3 software?
A: Yes — this breakout board is fully compatible with Mach3 and any other CNC control software that uses a standard parallel port interface. It exposes all 17 parallel port pins for maximum configurability.
Q: What is optocoupler isolation and why does it matter for a CNC breakout board?
A: Optocoupler (optical coupler) isolation uses light to transfer signals between circuits, completely separating your computer's electronics from the high-current CNC machine environment. This protects your PC from voltage spikes, electrical noise, and short circuits that are common in stepper motor systems.
Q: Can I control spindle speed with this board?
A: Absolutely. The board provides both a 0–10V analog output (P1 port) for connecting to a Variable Frequency Drive (VFD) and a PWM output for spindle governors with optocoupler inputs. A relay output on P17 handles spindle on/off switching.
Q: What power supply does this CNC interface board require?
A: The board logic is powered via the included USB cable, while the peripheral (stepper drivers, relay, etc.) accepts a wide-range 12–24V DC input. The two power domains are fully isolated from each other, protecting both your computer and your CNC electronics.
Q: How many stepper motor axes can this board control?
A: This board supports up to 5 independent stepper motor axes simultaneously, making it suitable for 3-axis, 4-axis, and 5-axis CNC routers, mills, laser cutters, and plasma cutting machines.
