4. Setup

4.1 Hardware Installation

Before connecting any components, ensure the power supply is disconnected.

1. Mounting: Securely mount the NVEM board within your control enclosure using appropriate standoffs and screws.
2. Power Connection: Connect a 12-32V DC power supply to the '12-32V IN' terminal block. Observe correct polarity (+ and -).

4.2 Software Configuration (MACH3)

The NVEM controller requires MACH3 software for operation. Ensure MACH3 is installed on your PC.

1. Driver Installation: Install the necessary NVEM plugin for MACH3. This typically involves copying a DLL file to the MACH3 plugins folder. Refer to the specific NVEM driver documentation for exact steps.
2. MACH3 Configuration:
   • Open MACH3 and navigate to Config > Ports and Pins.
   • Configure the motor outputs, input signals (limit switches, E-stop), and output signals (spindle, relays) according to the NVEM board's pinout diagram.
   • Set up motor tuning parameters (steps per unit, velocity, acceleration) for each axis based on your stepper motors and mechanical setup.
   • Configure spindle control settings if applicable.
3. Network Settings: Ensure the IP address of the NVEM board is correctly configured in the MACH3 plugin settings and matches your PC's network configuration.

5. Operating Instructions

Once hardware and software are configured, you can begin operating your CNC machine.

1. Power On: Turn on the power supply to the NVEM board and then launch MACH3 on your PC.
2. Homing: Perform a homing sequence (if configured) to establish the machine's absolute zero position.
3. Jogging: Use the manual jog controls in MACH3 or an MPG (Manual Pulse Generator) to move the axes and verify motor functionality.
4. Load G-code: Load your desired G-code program into MACH3.
5. Set Work Offset: Define your work coordinate system (G54, G55, etc.) by setting the X, Y, Z zero points for your material.
6. Start Program: Initiate the G-code program. Monitor the machine closely during the initial run.
7. Emergency Stop: In case of any malfunction or unsafe condition, immediately press the emergency stop button.

6. Maintenance

Regular maintenance ensures the longevity and reliable performance of your NVEM controller.

• Cleaning: Periodically clean the board and its enclosure to remove dust and debris. Use compressed air or a soft brush. Ensure power is off before cleaning.
• Connection Checks: Regularly inspect all wiring connections for looseness or corrosion. Tighten any loose terminals.
• Environmental Control: Maintain a stable operating environment, avoiding extreme temperatures and humidity.
