MACH3 CNC Interface Board 5 Axis Stepper Motor Driver Control Card Parallel Port CNC Engraving Machine Controller With USB Cable

MACH3 CNC Engraving Machine Interface Board

📌 Product Overview This MACH3 CNC control interface board is a professional parallel‑port motion controller for engraving machines and CNC equipment. It adopts optocoupler isolation design for input signals, separates USB power supply and peripheral power supply to protect computer equipment. It supports 5‑axis stepper motor drive control, reserved relay output and 0‑10V analog / PWM spindle speed regulation interface, compatible with MACH3 CNC control software. Wide‑voltage 12‑24V power input with reverse‑connection protection. Clearly marked terminals simplify wiring, suitable for DIY engraving machines, small CNC lathes and milling machine transformation projects. ✨ Core Features

1. Works with MACH3 and other parallel‑port CNC control software
2. Independent USB power and peripheral power design for computer safety protection
3. 12‑24V wide‑voltage input with reverse‑connection protection circuit
4. Optically isolated input terminals, supports emergency stop, tool setting and limit switch signals
5. Onboard relay output (Port P17) for spindle switch control
6. Isolated 0‑10V analog output or PWM signal (Port P1) for inverter spindle speed adjustment
7. 17 open optically‑isolated ports, capable of driving 5‑axis stepper motor drivers
8. Compatible with common‑anode and common‑cathode drivers with 5V logic level
9. Clear silk‑screen pin definition on PCB for fast wiring and maintenance
10. Compact size, stable anti‑interference performance for long‑time CNC operation

📐 Dimension Info Board size: 90.8mm × 70mm Net weight: 84g (including USB cable) ⚠ Important Usage Notice The host computer needs a native physical parallel port; virtual USB‑to‑parallel adapters are not supported. MACH3 software is adapted for Windows XP and Windows 7 32‑bit systems; Windows 7 64‑bit version cannot run normally. 🛠 Application Scenarios DIY CNC engraving machine, small milling machine modification, 5‑axis motion control system, stepper motor control, spindle variable‑speed control, desktop CNC equipment retrofitting.
