5. Operation

5.1. Basic Engraving/Cutting Process

1. Prepare Material: Place your material (e.g., wood, acrylic, metal) within the 300x300mm engraving area. For cutting, consider using metal cutting plates to protect the workbench.
2. Load Design: Open the software on your computer or mobile device. Import your design file (JPEG, SVG, PNG, BMP, DXF, AI, PLT).
3. Adjust Settings: Set engraving/cutting parameters such as laser power (e.g., 20W for blue light laser, 1W for infrared laser), speed, and passes based on the material.
4. Preview: Use the software's preview function to ensure the design is correctly positioned.
5. Start Operation: Initiate the engraving or cutting process. Monitor the machine during operation.

10. User Tips

• For colored acrylic or glass engraving with the blue light laser, remember that you might need to apply color paper or paint the surface black for optimal results. The blue laser does not directly engrave in color.
• When engraving metal, the infrared laser is highly effective for achieving detailed results, including over 550 colors on stainless steel.
• Always ensure your material is securely placed and flat to achieve consistent engraving and cutting depth.
• Experiment with different power and speed settings on scrap material before working on your final project to find the best parameters for each material type.
