HOW IT WORKS

1. Create a local project from the home screen.

3. Choose a material preset and adjust processing settings.
4. Preview the engraved result on wood, metal, leather, or acrylic.
5. Export a machine-ready PNG or a material preview for client approval.

PERFECT FOR

• Laser engraving prep on the go
• Client preview mockups before production
• Testing contrast, threshold, and dithering settings
• Quick size checks in millimeters and pixels

The app prepares correct black/white artwork for your machine and a separate material preview. It does not generate G-code, because G-code depends on your specific controller, firmware, and machine setup.
