5. Setup and Installation
This section outlines the general steps for installing the AENBUSLM laser module onto a compatible CNC or laser engraving machine. Specific installation procedures may vary depending on your machine's model. Refer to your machine's manual for detailed instructions.
- Power Off: Ensure your laser engraving machine is completely powered off and unplugged from the power source before beginning installation.
- Mounting:
- Attach the provided slide rail to the laser module using the fixing screws.
- Mount the laser module assembly onto the designated carriage or mounting bracket of your laser engraving machine. Ensure it is securely fastened and stable.
- Electrical Connections:
- Connect the 3P line from the laser module to the corresponding laser control port on your machine's mainboard.
- Connect the external power cord to the laser module and then to a suitable power outlet.
- If applicable, connect the "First to second line + External power cord" as per your machine's wiring diagram.
- Air Assist Connection: Connect your external air pump (if not integrated) to the air assist port on the laser module. Ensure the air hose is securely attached.
- Software Configuration: After physical installation, configure your laser control software (e.g., LightBurn, LaserGRBL) to recognize and control the new laser module. Adjust laser power settings, speed, and other parameters as needed for your specific tasks.

6. Operating Instructions
Operating the AENBUSLM laser module involves preparing your material, setting up your design software, and initiating the engraving or cutting process.
- Material Preparation:
- Place the material to be processed on the machine's workbed. Ensure it is flat and securely held to prevent movement during operation.
- Verify the material is suitable for laser processing.
- Focus Adjustment:
- Use the provided focus fixing plate to set the correct focal distance between the laser lens and the material surface. This is crucial for optimal engraving and cutting results.
- Adjust the laser module's height until the focus plate indicates the correct distance.
- Software Setup:
- Open your laser control software (e.g., LightBurn, LaserGRBL).
- Import or create your design.
- Set appropriate parameters for laser power, speed, and passes based on the material type and desired outcome. Start with lower power and higher speed for testing, then adjust as needed.
- Ensure the work area in the software matches the physical placement of your material.
- Air Assist Activation: If using air assist, ensure your air pump is turned on and functioning. Air assist helps to blow away debris, reduce charring, and improve cutting performance.
- Initiate Operation:
- Before starting, ensure all safety precautions are in place, including wearing laser safety glasses.
- Start the engraving or cutting job from your software.
- Monitor the process closely. Do not leave the machine unattended.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your laser module.
- Lens Cleaning: The laser lens can accumulate dust and debris, affecting laser performance. Use a soft, lint-free cloth and lens cleaning solution (or isopropyl alcohol) to gently clean the lens regularly. Replace the protective lens if it becomes scratched or damaged.
- Module Exterior: Keep the exterior of the laser module clean and free from dust and residue. Use a soft, dry cloth.
- Air Assist Nozzle: Ensure the air assist nozzle is clear of any blockages. Clean it periodically to maintain efficient airflow.
- Connections: Periodically check all electrical and air assist connections to ensure they are secure.
- Storage: When not in use, store the laser module in a clean, dry environment, away from direct sunlight and extreme temperatures.
