Correct focus is crucial for sharp, accurate cuts. The AlgoLaser Delta 22W laser engraving machine comes with a focusing post or gauge to help you quickly find the right distance between the module and the plywood.
Here’s how to do it:
Lower the laser module until it’s close to the surface of the plywood.
Slide the focusing tool under the module.
Adjust the height until the bottom of the module just touches the tool.
Remove the tool and double-check that the module is parallel to the plywood.
This ensures the laser is precisely concentrated on the surface, giving you crisp edges and clean detail cuts.
