This is the second-generation laser module. Visually different from the first generation laser. It has cooling, chip, mounting screws, the ability to focus beam. Focusing better than first generation laser. He focused on focusing not on the point but on the line. This laser focuses on a very small point. Laser burn very thin lines. It's great. I also bought a laser controller from this seller. I recommend He optimized the work of the machines. Now the engraving has become extremely fast. Maximize the possibilities of machine tools. The opportunity to use the EleksCAM program has emerged. The controller works great with this program.
Very good. Powerful enough to cut cardboard and foam, too powerful for writing on paper.
