Laser Not Firing - Head not found - Yellow Light

The other day 75% of my left and right LED strip went bad at random. Then I received an error message stating head not found and had trouble focusing. Then my laser just completely stopped marking the material. I have no clue what is going on

Highest likelyhood is a bad black cable. They sell them in the Glowforge shop under parts, if in stock. They come and go in stock routinely. If you have warranty, support@glowforge.com and see if they’ll send you one.

Could be other issues but this is by far the most likely. The support area also has a tutorial on replacing the black cable.

Also: there’s some other links and things to look at in this thread.
