2. Safety Information
Operating a laser engraver requires strict adherence to safety protocols to prevent injury. This device is a Class 2 laser product (0.874 mW output power). Always prioritize safety.
- Eye Protection: Always wear the provided protective eyewear when the laser is in operation. Never look directly into the laser beam or at reflections.
- Emergency Stop: Familiarize yourself with the location and function of the emergency stop button. In case of any malfunction or hazard, immediately press this button to cut power to the laser.
- Work Area: Ensure the work area is clear of flammable materials. Do not operate the laser near explosive gases or vapors.
- Ventilation: Ensure adequate ventilation to dissipate fumes and particles generated during engraving.
- Unauthorized Use: Use the access key to prevent unauthorized operation of the machine.

5. Operating Instructions
This section outlines the basic steps for operating your laser engraver.
5.1. Focusing the Laser
Accurate focusing is crucial for optimal engraving results.
- Place your material on the workbed.
- Activate the red dot pointer (usually via software or a dedicated button).
- Adjust the height of the laser head using the manual focus knob until the two red dots from the pointer converge into a single, sharp dot on the material surface.
- The red dot guidance also provides an outline or pattern preview on the workpiece, aiding in precise positioning.

5.2. Using EzCad2 Software
The EzCad2 software is used to create and control your engraving projects. The device is also compatible with LightBurn software.
- Launch EzCad2 on your computer.
- Import or create your design. The software supports various image formats.
- Adjust laser parameters such as power, speed, frequency, and number of passes according to your material and desired effect.
- Use the preview function to verify the engraving area and pattern.
- Ensure protective eyewear is worn, then initiate the engraving process.

5.3. Rotary Axis Operation
The included rotary axis allows for engraving on curved or cylindrical surfaces.
- Attach the rotary axis to the laser engraver unit and connect it to the control unit.
- Secure the cylindrical object (e.g., ring, bracelet, cup) firmly in the rotary chuck.
- Adjust the height and position of the rotary axis and laser head to ensure proper focus and alignment with the object.
- Configure the rotary axis settings within the EzCad2 software for cylindrical engraving.
- Proceed with engraving as described in Section 5.2.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your laser engraver.
- Cleaning: Regularly clean the workbed and surrounding areas to remove debris and dust. Use a soft, lint-free cloth.
- Lens Care: The F-theta scanning lens is a critical component. Clean it gently with lens cleaning solution and a specialized lens cloth only when necessary, following manufacturer guidelines. Avoid touching the lens surface with bare hands.
- Cable Inspection: Periodically inspect all cables for signs of wear or damage. Replace any damaged cables immediately.
- Software Updates: Keep your EzCad2 or LightBurn software updated to the latest version for improved performance and features.
7. Troubleshooting
