4. 操作手順
4.1 Basic Operation with Mach3
Once the hardware is connected and software is installed, launch Mach3. The interface board will communicate with Mach3 to control your CNC machine. The maximum step-pulse frequency is 100KHz, suitable for both servo and stepping motors.
4.2 Using the Control Interface
The control interface allows for precise movement and control of your CNC machine. This includes:
- 4-Axis Linkage: Supports simultaneous control of four axes (X, Y, Z, A).
- ジョギング： Manually move each axis for setup and positioning.
- ホーミング： Return axes to their home positions.
- Probing: Utilize a probe switch for automatic tool length measurement or workpiece referencing.

5. メンテナンス
To ensure the longevity and optimal performance of your Mach3 USB Interface Board, follow these maintenance guidelines:
- Keep the board clean and free from dust and debris. Use compressed air or a soft brush for cleaning.
- Ensure the operating environment is dry and free from excessive humidity to prevent corrosion.
- ボードを極端な温度にさらさないでください。
- すべての配線接続部の締め付け具合や摩耗の兆候を定期的に確認してください。
6。 トラブルシューティング
6.1 接続の問題
- ボードがコンピューターに認識されません: Ensure USB drivers from the provided CD are correctly installed. Try a different USB port or cable.
- Mach3 software not communicating: Verify that the correct Mach3 plugin for the USB interface board is selected and configured.
6.2 運用上の問題
- Motor movement erratic or incorrect: Check motor driver connections and ensure pulse/direction signals are correctly configured in Mach3. Verify power supply to the board and motor drivers.
- 干渉の問題: The board is designed with strong anti-interference capabilities. However, ensure proper grounding of your CNC machine and use shielded cables where necessary to minimize electrical noise.
- Limit switch or E-stop not functioning: Confirm correct wiring of general-purpose inputs and proper configuration in Mach3.
6.3 ソフトウェアの互換性
While the board is designed for Mach3, ensure your operating system (e.g., Windows version) is compatible with the Mach3 version and drivers provided. Consult Mach3 documentation for specific OS requirements.
