Glass Engraving with Blue laser Diode

5.5w laser has enough power to engrave on glass but not without trick
The only thing that must be done is painting it with black color (with brush or spray) and after engraving just clean it. The result is so impressive.
Max Laser power: 80%
Speed: 500 mm/min
Software: Lasergrbl or Lightburn
