5. Operating Instructions

Once set up, the SCULPFUN C1 is ready for engraving. Ensure your material is placed flat on the working area.

1. Material Placement: Place the material to be engraved within the 150x130mm working area.
2. Focusing: Use the provided acrylic focusing sheet to set the correct focal distance for the laser. Place the sheet under the laser head and adjust the laser head's height until the laser spot is at its finest point on the material. Secure the laser head.
3. Software Interface: Open your chosen software (LightBurn or LaserGRBL). Import your desired image (supports JPG, PNG, BMP, GIF, SVG, AI, etc.).
4. Parameter Settings: Adjust engraving parameters such as speed, power, and interval based on your material and desired effect. The C1 can reach a maximum speed of 10000mm/min for some materials.
5. Framing: Use the "Frame" function in the software to preview the engraving area on your material. This helps ensure correct positioning.
6. Start Engraving: Once satisfied with the settings and framing, initiate the engraving process from the software.

6. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your SCULPFUN C1.

6.1. Laser Lens Cleaning

Dust and debris can accumulate on the laser lens, affecting engraving quality. Clean the lens regularly:

1. Power off and unplug the machine.
2. Carefully remove the magnetic protective cover from the laser head.
3. Unscrew and remove the black lens cap from the bottom of the laser head.
4. Use a clean cotton swab lightly dampened with lens cleaning solution (or isopropyl alcohol) to gently wipe the lens. Avoid excessive pressure.
5. Allow the lens to dry completely before reassembling the lens cap and protective cover.

6.2. Belt Adjustment

Ensure the belts are properly tensioned for accurate movement of the laser head.

1. Inspect the belts for any looseness or wear.
2. If a belt is loose, use the provided repair tools to adjust the tensioning screws on the belt mechanism until the belt is taut but not overly tight.
3. For balance adjustment, loosen the screws on the coupling, push the gantry fully against the frame, and then re-tighten the screws. This ensures both sides of the gantry are aligned.

7. Troubleshooting

• Machine not connecting to computer:
  • Ensure the data cable is securely connected to both the machine and the computer.
  • Verify the machine is powered on (green light should be steady or flashing).
  • For Windows 7, check if the necessary drivers are installed. Refer to the software installation section.
  • Try a different USB port or data cable.
• Engraving quality is poor/faint:
  • Check the laser focus. Re-focus the laser using the acrylic focusing sheet.
  • Clean the laser lens as described in the Maintenance section.
  • Adjust software parameters (increase laser power, decrease speed, or reduce interval).
  • Ensure the material is suitable for laser engraving and is placed flat.
• Machine not moving correctly/making grinding noises:
  • Check for any obstructions in the gantry's path.
  • Inspect and adjust the belts for proper tension as described in the Maintenance section.
  • Ensure the machine is on a stable, level surface.
• Strong fumes/smell during engraving:
  • This is normal for many materials. Ensure adequate ventilation. Operate in a well-ventilated room, near an open window, or use an external fume extractor.
