When using a laser cutter or engraver, adjusting key settings is crucial for achieving optimal results on different materials. Here are the primary settings to consider:

• Power: The power setting determines the intensity of the laser beam. For softer materials like wood and acrylic, a lower power (30-50%) is often sufficient, while harder materials like metal may require higher power (70-100%).
• Speed: This setting affects how quickly the laser moves across the material. Slower speeds (10-20 mm/s) are ideal for engraving deeper, while faster speeds (30-100 mm/s) can be used for cutting thinner materials.
• Frequency: The frequency setting is essential for engraving. Higher frequencies (300-1000 Hz) produce finer details and smoother finishes on materials like acrylic, whereas lower frequencies (1-10 Hz) are suited for deeper engravings on wood or leather.
• Focus: Proper focus of the laser beam is critical. Ensure that the laser is focused correctly for each material type to achieve cleaner cuts and precise engravings.

Always test settings on sample pieces to refine your approach based on specific materials and desired results.
