4.2. Focusing the Laser

Proper focusing is crucial for optimal engraving and cutting results. Use the provided focus fixing plates to set the correct focal distance.

1. Place the material to be engraved or cut on the work surface.
2. Select the appropriate focus fixing plate (3mm, 4mm, or 5mm) based on your material thickness and desired operation (cutting or engraving).
3. Position the laser module so that the bottom of the focus fixing plate just touches the surface of your material.
4. Secure the laser module in this position.
