7. Basic Operation
This section outlines the fundamental steps for engraving and cutting.
7.1. Material Placement
Place the material to be engraved or cut flat on the working surface. Ensure it is stable and does not move during operation.
7.2. Focusing the Laser
The S30 uses a fixed focus column and sliding device for focusing. Position the laser module over the material and adjust its height until the laser beam is at its smallest point on the material surface. This ensures optimal engraving and cutting performance.

7.3. Preparing Your Design
Import your design into the software (e.g., LightBurn). Adjust parameters such as power, speed, and number of passes according to the material type and desired outcome. For automatic air assist, ensure the M8 command is enabled in LightBurn for cutting operations.
7.4. Starting Operation
Once the design is prepared and the laser is focused, initiate the engraving or cutting process from the software. Monitor the machine closely throughout the operation.
8. Maintenance
Regular maintenance ensures the longevity and optimal performance of your SCULPFUN S30.
- Clean Laser Lens: Periodically clean the laser lens with a soft, lint-free cloth and lens cleaning solution to maintain beam quality.
- Clear Debris: Remove any accumulated dust, debris, or material residue from the machine's frame, rails, and working area after each use.
- Lubricate Rails: Apply a small amount of lubricant to the X and Y axis guide rails periodically to ensure smooth movement.
- Check Connections: Ensure all electrical and air assist connections are secure and free from damage.
- Air Pump Filter: If applicable, check and clean or replace the air pump filter to maintain optimal airflow.
9. Troubleshooting
