In this article, we covered the setup of the laser cooling system, the laser exhaust system, the relevant laser safety measures, and the initial setup and testing of the laser machine.

The following instructions for testing the laser engraver are intended to supplement the instructions in Section 3.9 of the OMTech Manual - Initial Testing.

When laser engraving or cutting, the material vaporizes under the laser beam and then condenses into smoke. Although it is ideally removed from the laser by a blower, smoke particles collect on mirrors and lenses over time. Therefore, it is important to clean the laser mirrors and focusing lenses.
