3.3. Electrical Connection and Compatibility
Connect the laser module using the provided 3-pin input cable to your machine's control board. The module requires DC 12V 1.8A (1.5A-2A) input and supports 5V PWM modulation. If your machine's interface is not directly compatible (e.g., 4-pin or 24V), use the included driver adapter and an appropriate power supply.
The laser module is compatible with most laser engraver cutter brands on the market, such as Atomstack and Ortur, and supports software like LaserGRBL and LightBurn. It is compatible with Win XP / Win 7 / Win 8 / Win 10 and MACOS operating systems.

3.4. Focus Adjustment
The laser module has a 23mm fixed focal length. Use the provided focus fixing plates to set the correct distance between the laser head and the material. For example, to cut 4mm plywood, select the 3mm focus fixing plate.

4. Operating Instructions
4.1. Material Compatibility and Performance
The LT-40W-F23 module is suitable for engraving and cutting a wide range of materials, including MDF, wood, paper, leather, bamboo, plastic, rubber, alumina, and stainless steel. It can engrave mirror stainless steel without needing to paint it black. The module offers a fast engraving speed, up to 800mm/min for 304 stainless steel, and excellent cutting ability, such as cutting 4mm thick plywood in one pass at 120mm/min.
Note: This laser module is unable to engrave blue, purple, white, or transparent materials, or aluminum without an oxide layer.

4.2. Engraving and Cutting Process
After securing the material and setting the correct focus, use your chosen engraving software (e.g., LaserGRBL, LightBurn) to prepare your design. Adjust the speed and power settings according to the material and desired outcome. The module's beam compressed spot technology ensures high engraving speed and precision.

5. Maintenance
5.1. Lens Cleaning
Regular cleaning and maintenance of the laser lens are crucial for maintaining good cutting results and extending the service life of the module. Use a soft, lint-free cloth and appropriate lens cleaning solution. Avoid touching the lens directly with your fingers.
5.2. General Care
Keep the laser module free from dust and debris. Store it in a dry, cool environment when not in use. Ensure proper ventilation during operation to prevent overheating.
6. Troubleshooting
6.1. Common Issues
- No Laser Output: Check all electrical connections, including the 3-pin cable and driver adapter. Ensure the power supply meets the DC 12V 1.8A requirement. Verify software settings for laser activation.
- Poor Engraving/Cutting Quality:
- Verify the focus is correctly set using the focus fixing plates.
- Clean the laser lens if it appears dirty.
- Adjust engraving/cutting speed and power settings in your software.
- Ensure the material is compatible with the laser module (e.g., not transparent or blue/purple).
- Module Not Recognized: Confirm compatibility with your machine's control board and operating system. Ensure the driver adapter is correctly installed if needed.
