3.2 Precision Engraving

The unique spot compression technology provides a precise spot size of 0.08 x 0.1 mm, ensuring high engraving accuracy of 0.01 mm. The fixed laser focusing mode eliminates the need for manual focusing.

The ATOMSTACK A20 Pro V2 offers 0.01mm precision engraving due to its optimized spot size.

3.3 Resume Engraving Function

The second-generation application allows activation of the resume engraving function. If work is interrupted due to an unexpected power failure, the operation can be continued from the original position, provided the relative position between the machine and the workpiece remains unchanged. This feature minimizes material waste.

The 'Resume Engraving' feature allows continuation of work after power interruptions.

4. Maintenance

4.1 Air Assist System

The ATOMSTACK F30 V2 Air Assist system is crucial for maintaining optimal laser performance. It features an adjustable airflow of 10-30 L/min, effectively removing smoke and dust generated during laser cutting and engraving. This prevents smoke and dust from attenuating laser energy, ensuring stable and consistent results. Regularly check and clean the air assist nozzle to ensure proper function.

4.2 General Cleaning

Keep the machine clean from dust and debris. Use a soft, dry cloth to wipe down surfaces. Ensure the linear guides are free from obstructions to maintain smooth laser movement.

5. Safety Information

The ATOMSTACK A20 Pro V2 incorporates several safety features to protect users during operation:

• Laser Shield: A protective laser shield is integrated to protect the user's eyes, eliminating the need for additional protective glasses in some cases. However, always use the provided safety glasses for maximum protection.
• Eye Protection Design: The laser module features a magnetic filter cover that blocks 97% of intense light. This cover is easily disassembled for cleaning.
• Limit Switches: Integrated limit switches (one for X-axis, one for Y-axis) prevent the laser head from exceeding the engraving area.
• Tilt Safety Alarm: The device is equipped with a gyroscope that triggers an audible safety alarm if the machine is tilted beyond 15 degrees.
• Flame Detector: A flame detector is included to enhance safety during operation.
• Pet Safety: The laser shield also helps prevent pets from detecting the laser point.

6. Troubleshooting

This section provides general guidance for common issues. For specific technical support, please refer to the manufacturer's official support channels.

• Poor Engraving/Cutting Quality: Ensure the material is clean, the laser focus is correct (fixed focus), and the air assist system is functioning properly to remove smoke and debris. Verify laser power and speed settings are appropriate for the material.
• Machine Not Responding: Check all cable connections (USB, power). Ensure the software is correctly installed and communicating with the machine. Restart the machine and computer if necessary.
• Unexpected Stops: Check for power interruptions. The 'Resume Engraving' function can be used if the workpiece has not shifted. Ensure no safety alarms (e.g., tilt sensor) have been triggered.
