No laser firing from the printhead

My unit was just “going through the motion” without the laser beam. I tried numerous attempts but still no go. The tube doesn’t glow like before… oh boy. Has anyone encountered similar issues?

Have you tried on a known good file - one of the freebies like the Founders Rulers?

Check the power setting too - I just accidentally ran through an entire engrave with the power set to 1.



I was using the same file that was successfully printed out before.

I had to adjust the power and speed to test the plywood from Home Depot. So I did triple check the settings. Sometimes it won’t cut all the way through because of some knots/voids. :joy: I will try again this weekend.

Did you, by chance, just clean the lens and windows right before this?

I cleaned it AFTER. I thought it may be too dirty and causing it not to beam properly.

No tube glow? That’s a bad sign. Sounds like the laser isn’t firing at all.

Thanks for the advice. Felt like I was talking to a celebrity :grin:

Who, @Rita? (Naw, she’s cool! Very down to earth, and so incredibly patient with all of my flubs.) :wink:

Here’s the link to a short recording of the issue…

Thank you so much for taking the time to provide more detail, and the video. Unfortunately, it looks like your unit is experiencing an issue that we can’t resolve remotely. I want you to have a reliable unit, so I’m recommending we replace this one. I’ll be in touch via email to sort out the details.
