Achieving optimal engraving quality requires understanding the characteristics of each material and adjusting your laser settings accordingly. Here are some tips for different materials:

• Wood: Use a lower speed and higher power for deeper engravings in softer woods like pine. Hardwood may require a faster speed with lower power to avoid burning.
• Acrylic: For clear acrylic, utilize a high speed and low power to achieve a clean cut and avoid melting. For colored acrylic, adjust the settings to emphasize color depth without excessive burning.
• Metal: Metal engraving requires high power and slow speed. Ensure your machine is equipped with a high-powered laser capable of cutting through metal. Use a raster engraving technique for detailed designs.
• Glass: Sandblasting is often preferable for glass, but if you’re using a laser, opt for low speed and high frequency to minimize cracking. Use a masking tape to protect areas from unwanted engraving.
• Leather: A medium speed with high power works well for leather, but consider adjusting based on the type of leather, as thinner materials may require quicker settings to prevent burning.

Always conduct a test engraving on a scrap piece of material to ensure your settings are optimal before starting your final project.
