Glowforge Laser Not Working/Firing

Hi everyone!

I am running into an issue where the laser on my Glowforge stopped firing, partially through a project. I only noticed once the cutting has ended and I came back to a partially cut acrylic. I then started a new project with a new piece of acrylic, just to test to see if the laser is firing, and recorded a video. I have tried:

  1. Following the cleaning procedures on the Glowforge website.
  2. Cleaning the glass tube as instructed.
  3. Ensuring that the cables are plugged in all the way and the pins are straight.

At this point, I am unsure what to do. As you can see in the video, normally I can see the lasers firing in the tube, but now there is no activity.

Please advise and thank you!

Welcome to the community. A couple of things could be the cause…
double check your power setting and make sure it didn’t default to ‘1’…which will do nothing. Also, if by chance your design has duplicate layers, they will cancel each other out and nothing will be engraved / cut.
It is not necessary to clean the glass tube at all, except for cosmetic reasons. It’s the optics (lenses, mirrors, etc) that require cleaning.
