So I have read a couple of post about the laser… I have had my Glowforge since May 2020. I ran different files including proof grade materials and I checked the settings using full power and nothing. The Glowforge runs but no laser coming out. I disconnected it, cleaned the lenses and still nothing? I am stuck on what else it can be? I used it 2 weeks ago with no issue and now the laser won’t turn on? Anybody had same issues after trying what I have done already? Thank you in advance
Posting here has opened a service ticket with support so they will be along in a bit. Dont send them an email as that just duplicates work orders and slows things down. My guess would be something with the power supply.

Check the connections of the white cable that goes to the head.
I disconnected it a couple of times and still nothing
Support will ask you to run the gift of good measure on a piece of draftboard, and then pictures of all of your optics.

Scratching at straws, but have you tried a known good design? Duplicate lines can cancel each other out and cause the laser not to fire.
I tried a small business card holder from the Glowforge site with PG material and still nothing… I uploaded a video to show what it is doing or not doing in this matter
This means that it’s did not default to power of 1, then…right?
It did at first but I changed it to full power… I also tried 100 power… but it didn’t do anything

I am having the same problem? please let me know if you figure it out before me.
Posting in Problems & Support opens a support ticket, and there can only be one customer per ticket. If you’re having problems too, you should start your own thread so you can get some help. 
I see you already emailed us about this and we’re working on it there, so I’m going to close this topic.
