Preparing design files and wood for precise laser cutting and clean engravings involves several crucial steps:

1. Design Optimization: Start by creating vector files using software like Adobe Illustrator or CorelDRAW. Ensure all lines are set to the correct stroke weight—typically 0.001 inches for cutting and 0.01 inches for engraving. Use RGB colors for different operations; typically, red for cut and blue for engrave.
2. File Format: Export your design files in compatible formats like SVG, AI, or DXF. Check your laser cutter’s specifications for preferred formats.
3. Material Selection: Choose high-quality wood suitable for laser cutting. Plywood, MDF, and hardwoods like birch or maple provide different finishes and cut properties.
4. Material Preparation: Sand the wood surface to ensure a smooth finish and clean engravings. Remove any dust or debris to avoid imperfections.
5. Testing: Conduct test cuts and engravings on scrap wood to fine-tune speed, power settings, and ensure desired outcomes.
6. Setting Up: Secure the wood properly on the laser bed to prevent movement during cutting and engraving operations.
