4. Operating Instructions
After successful installation, your SCULPFUN engraver now has an expanded working area of 410 x 950mm. To utilize this larger area, you must update the device size settings in your engraving software (e.g., LightBurn).
4.1 Software Configuration (LightBurn Example)
- Open LightBurn: Launch your LightBurn software.
- Access Device Settings: Navigate to the device settings or machine settings menu.
- Modify Working Area: Change the X-axis length to 405mm and the Y-axis length to 945mm (or 950mm, depending on the exact model and software version). This will update the virtual workspace to match your physical expanded area.
- Verify: Ensure the software reflects the new, larger working area.

You can now engrave or cut larger objects such as paintings, tables, benches, doors, or skateboards. The expansion kit maintains the same accuracy and stability as the standard SCULPFUN S6/S6 Pro/S9/S9 Pro machine.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your expansion kit and laser engraver.
- Clean Rails and Belts: Periodically inspect and clean the Y-axis rails and belts to remove dust and debris that could affect smooth movement and accuracy.
- Check Belt Tension: Ensure the extension belts remain properly tensioned. Loose belts can lead to inaccurate engraving or cutting.
- Inspect Cables: Regularly check all cables for any signs of wear, fraying, or damage. Ensure they are securely connected.
- Secure Connections: Verify that all screws and fasteners on the frame and extension shafts are tight. Loose connections can impact stability.
6. Troubleshooting
If you encounter issues after installing the expansion kit, consider the following:
- Inaccurate Engraving/Cutting:
- Check belt tension. Overly loose or tight belts can cause skipping or distortion.
- Ensure all frame connections are secure.
- Verify software settings for the working area (X: 405mm, Y: 945mm/950mm) are correctly applied.
- Cables Getting in the Way:
- Implement proper cable management to prevent cables from snagging or interfering with the laser head's movement. Use cable ties or clips to secure them along the frame.
- Laser Not Functioning (after cable replacement):
- Double-check all cable connections to the control board and laser module. Ensure they are fully seated and correctly oriented.
- Confirm that the correct extension cable (single-line, two-wire, or four-wire) was used for your specific engraver model.
- Kit Not Compatible with S10:
- This expansion kit is designed for SCULPFUN S6, S6 Pro, S9, and S9 Pro models only. It is not compatible with the S10 series.
