2. Safety Precautions & Usage Restrictions

Your safety is paramount. Adhere to all warnings and instructions to prevent injury or damage to the device.

2.1 Warning Statements

• Laser Radiation Hazard: This device contains a high-power laser module. Direct or indirect exposure to the laser beam can cause severe eye damage or burns. Always wear laser safety goggles matched to the 445±nm wavelength during operation.
• Fire and Smoke Hazard: The laser processing process generates high temperatures, posing a high risk of igniting materials. Ensure proper ventilation and never leave the machine unattended during operation.

2.2 Material Restrictions

Engraving or cutting of the following materials is strictly prohibited due to the release of toxic fumes or fire hazards:

• PVC (polyvinyl chloride)
• Fluorinated plastics (e.g., PTFE)
• Any material that produces toxic or corrosive fumes when heated.

2.3 Environmental Requirements

The working environment should be stable, well-ventilated, and free from flammable materials. Maintain a clean workspace to prevent dust and debris from interfering with machine operation.

2.4 Device Protection

• Do not operate at full power continuously beyond the maximum continuous duty time specified in the product manual to prevent overheating.
• Prohibited Actions: Unauthorized disassembly of the laser module, electrical circuit modification, or removal of safety interlocks is strictly forbidden and will void the warranty.

5.3 Material Fixturing and Focusing

Securely and evenly fix the workpiece onto the worktable. Adjust the laser focus precisely to the material surface for optimal engraving/cutting results.

6. Operating Instructions

6.1 Parameter Setup and Test Run

In the control software, set appropriate power, speed, and pass count according to the material type and thickness you are working with. Always perform a small test run on scrap material to verify settings before starting the main project.

6.2 Starting Processing

Close the protective cover and activate the exhaust system. Once ready, send the processing command from the software.

6.3 Ending Operation

After processing completes, wait until the device has fully stopped and the laser head has completely cooled before handling the workpiece or machine.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your CNC router.

• Keep the machine clean and free of dust and debris, especially around the laser module and moving parts.
• Periodically check all connections (USB, power) to ensure they are secure.
• Inspect the laser lens for any residue and clean gently if necessary, following manufacturer guidelines for laser optics.
• Ensure the exhaust system is clear and functioning effectively to remove smoke and fumes.

8. Troubleshooting (FAQ)

Q1: What should I do if engraving/cutting depth is insufficient?

A: Please check the following sequentially:

1. Whether the laser focus is precisely aligned to the material surface.
2. Whether the power and speed settings in the software are appropriate for the material.

Q2: Why are engraving edges unclear or charred?

A: This is typically caused by excessive power or insufficient speed. Reduce the power percentage or increase the travel speed in the software settings.

Q3: Why is the device not recognized after connecting to the computer?

A: Please verify:

1. Whether the USB cable is undamaged and securely connected.
2. Whether the device's USB driver is correctly installed on your operating system.

Q4: Why does the laser head emit no light?

A: Please check:

1. Whether all power connections are secure and functional.
2. Whether the “Laser Enable" option is activated in the software.

Q5: How thick a material can be cut?

A: Cutting capability depends on laser power, material properties, and focal length. For common 3 mm basswood or acrylic sheets, the machine is capable of cutting.

9. User Tips

• Always start with lower power and higher speed settings for new materials and gradually adjust to find the optimal parameters.
• For intricate designs, consider multiple passes at lower power to achieve cleaner cuts and engravings.
• Regularly back up your design files to prevent loss.
