The motorized Z-axis allows for precise focal length adjustment, which is crucial for optimal engraving and cutting results.
6. Operating Instructions
6.1 Loading Material
Place your material flat on the working bed. Ensure it is securely positioned and does not obstruct the laser path or movement of the gantry.
6.2 Focusing the Laser
The NEJE Max4 V2 E80 features a motorized Z-axis for precise focus adjustment. You can set the focal length for each layer in LightBurn software. For thicker materials (20-25mm), the motorized Z-axis allows for automatic and efficient layer-by-layer cutting by adjusting the height.
6.3 Setting Parameters (Speed & Power)
Adjust laser speed and power settings in your software based on the material type and desired outcome (engraving or cutting). Refer to the material compatibility section in the specifications for guidance. The machine boasts a maximum speed of 1000mm/s and an acceleration of 100,000 mm/s² for industry-leading work efficiency.
6.4 Starting a Job
Once the material is loaded, focused, and parameters are set, initiate the engraving or cutting job through your software. Monitor the process closely.
6.5 Air Assist
The machine supports an air flow rate of 0-60 L/min. Utilizing air assist can significantly improve cutting quality and reduce charring on materials.
7. Maintenance
7.1 Cleaning
- Regularly clean the laser lens with a specialized lens cleaning solution and cloth to maintain optimal performance.
- Wipe down the machine frame and working area to remove dust and debris.
7.2 Linear Guide Rails
The industrial-grade linear guide rails are designed for smooth, long-lasting operation. They feature electroplating for rust prevention and CNC base calibration. These components are replaceable, ensuring an ultra-long service life for your machine.
7.3 Belt Tensioning
The machine is equipped with an auto-tensioning belt system. Periodically inspect the belts for wear and tear, though manual adjustment should be minimal due to the auto-tensioning feature.
7.4 Firmware Updates
NEJE provides OTA (Over-the-air) software and firmware update services. Regularly check for and install updates to ensure your machine has the latest features and performance enhancements.
8. Troubleshooting
If you encounter issues with your NEJE Max4 V2 E80, consider the following common problems and solutions:
- Poor Engraving/Cutting Quality:
- Check laser focus. Ensure the motorized Z-axis is correctly set for the material thickness.
- Verify laser power and speed settings are appropriate for the material.
- Clean the laser lens.
- Ensure the material is flat and securely placed.
- Check for any vibrations; the machine has MEMS Vibration Protection, but external factors can still affect quality.
- Machine Not Connecting:
- Ensure USB cable is properly connected or Bluetooth is paired.
- Restart the software and the machine.
- Check for driver issues on your computer.
- For wireless offline mode, ensure you are within the 10-meter range.
- Inaccurate Engraving/Cutting:
- The machine has a repetition accuracy of 0.1mm and mechanical accuracy of 0.01mm. If results are outside this, check for loose belts or components.
- Ensure the material is not shifting during operation.
- Verify software settings for scaling or positioning.
