I received my Laser Engraver today, Ortur Master 15W. I assembled the kit (also re-assembled). I downloaded Lightburn activated the trial and connected the laser.
Clicked on A symbol to add text. Once the text is added which is simple (TY), I used the default setting Lightburn provided 3000/min and 20% power. Nothing happened. Changed the power, yet nothing happened. Adding link to the video.
