Achieving optimal photo engraving results with a laser requires careful attention to various settings. Here are essential parameters to consider:

• Power Settings: Use a lower power setting for engraving photos, typically between 30% to 50% of the total power of your laser. This prevents excessive burning and allows for better details.
• Speed: Set the engraving speed higher, around 300 to 600 mm/s, depending on your machine and material. A faster speed reduces the risk of over-burning and preserves the finer details of the image.
• DPI (Dots Per Inch): A higher DPI, ranging from 300 to 600, results in finer detail reproduction. Adjust the DPI setting based on the material and the desired quality.
• Frequency: Set the frequency to low or medium (usually 500 to 1000 Hz) to enhance the engraving’s tonal quality. This setting can affect how the laser interacts with the material.
• Material Type: Different materials (wood, acrylic, metal) may require adjustments in settings. Conduct test engravings to find the best combination for each material.

Experimentation is key. Always perform test runs to optimize these settings for your specific laser engraver and material combinations.
