5. Safety Information

Always observe the following safety precautions to prevent injury or damage to the equipment:

• Electrical Safety: Ensure all power connections are made correctly and securely. Disconnect power before making or changing any wiring connections.
• Professional Installation: Installation and setup should ideally be performed by individuals with experience in CNC systems and electrical wiring.
• Environment: Operate the control card in a clean, dry environment, free from excessive dust, moisture, and extreme temperatures.
• Grounding: Ensure your CNC machine and all associated electrical components are properly grounded.
• Emergency Stop: Always have an accessible emergency stop button for your CNC machine.
• Read Documentation: Refer to the MACH3 software documentation for specific software-related safety guidelines.

6. Setup and Installation

6.1. Hardware Connections

Before connecting the control card, ensure all power to your CNC system is off. The NVCM V2.1 card requires connections for power, USB communication, motor drivers, and optional inputs/outputs (e.g., limit switches, emergency stop).

1. Power Supply: Connect a suitable DC power supply to the designated power input terminals on the NVCM V2.1 card. Refer to the card's markings for voltage requirements (typically 12-24V DC).
2. USB Connection: Connect the control card to your computer using a standard USB cable. This provides the communication link for MACH3.
3. Motor Driver Connections: Connect the PUL (Pulse), DIR (Direction), and ENA (Enable) signals from the NVCM V2.1 card to the corresponding inputs on your stepper or servo motor drivers for each axis (X, Y, Z). Ensure proper common ground connections.
4. Limit Switches & E-Stop: Connect limit switches, home switches, and the emergency stop button to the designated input terminals on the control card. Consult the wiring diagram provided with your specific NVCM V2.1 model for exact pin assignments.
5. Spindle Control (Optional): If your system includes spindle control, connect the relevant output signals from the NVCM V2.1 to your spindle VFD or relay.

6.2. Software Installation and Configuration

After hardware connections are complete, install and configure the necessary software:

1. MACH3 Installation: Install MACH3 CNC software on your computer if not already present.
2. NVCM Plugin: Install the specific NVCM plugin for MACH3. This plugin is essential for MACH3 to communicate with the NVCM V2.1 control card. The plugin typically comes with the control card or can be downloaded from the manufacturer's support website.
3. MACH3 Configuration:
   • Open MACH3 and navigate to Config > Ports and Pins.
   • Under Motor Outputs, enable and configure the Step/Dir pins for X, Y, and Z axes according to your wiring diagram.
   • Under Input Signals, configure your limit switches, home switches, and E-Stop.
   • Under Motor Tuning, set the steps per unit, velocity, and acceleration for each axis. This is crucial for accurate movement.
   • Ensure the NVCM plugin is selected as the motion control device.
4. Testing: After configuration, perform basic tests such as jogging each axis to verify correct movement and direction.

7. Operating Instructions

Once the NVCM V2.1 card is installed and configured, you can begin operating your CNC machine with MACH3.

1. Power On: Turn on the power to your CNC machine and the NVCM V2.1 control card.
2. Launch MACH3: Start the MACH3 software on your computer. Ensure the NVCM plugin initializes correctly.
3. Homing: Perform a homing sequence (if configured) to establish the machine's absolute zero position.
4. Jogging: Use the keyboard arrows or MACH3's on-screen controls to manually jog each axis and confirm smooth movement.
5. Load G-Code: Load your desired G-code file into MACH3 (File > Load G-Code).
6. Set Work Offset: Set your work offset (G54, etc.) and zero the axes at your desired starting point on the workpiece.
7. Start Operation: Click the "Cycle Start" button in MACH3 to begin the CNC program. Monitor the machine closely during operation.
8. Pause/Stop: Use the "Feed Hold" button to pause the program or the "Stop" button to halt it completely. In an emergency, press the physical E-Stop button.

8. Maintenance

The JIANGFAN NVCM V2.1 control card is designed for reliable operation with minimal maintenance. However, regular checks can help ensure longevity and performance:

• Keep Clean: Periodically clean the control card and its enclosure to prevent dust and debris buildup, which can affect cooling and electrical conductivity. Use a soft, dry brush or compressed air.
• Check Connections: Regularly inspect all wiring connections for tightness and signs of wear or corrosion. Loose connections can lead to intermittent operation or damage.
• Environmental Control: Ensure the operating environment remains within specified temperature and humidity ranges.
• Software Updates: Keep your MACH3 software and NVCM plugin updated to the latest stable versions to benefit from bug fixes and performance improvements.
