I did a usual run on my Glowforge Plus with proofgrade materials this morning with no issue. I loaded in a new (similar) file and ran it again. It only engraved half of the file and didn’t cut anything. Ever since it will move as though it is running but no marks are made. I’ve done the following and am losing hope and patience:
Cleaned all cameras, mirrors, lenses
Restarted the machine and my computer
Tried using the “Gift of Good Measure” file and the same thing happens so I don’t think it is a file issue
Customer support will get back to you with next steps. If you’re sure all the optics are properly in place and there’s no output at all, then you have a hardware issue that’s going to require replacement of the machine, so start working on your backup plan if you need to laser anything in the near term. The Glowforge User Group and Glowforge World groups on Facebook are a good place to find other owners in your city that can help run some jobs for you while you wait for your replacement.
