It looks like the one of the updates dims the lights after not being used for a while. It takes a new snapshot of the bed when this happens. I had placed a piece with snapmarks in the glowforge and while preparing the project, the lights dimmed and it could no longer recognize the snapmarks. It would be nice if clicking on the snapmark button turned the lights back on and captured a new image of the bed
That’s the new sleep mode.
Thanks for the answer @wesleyjames, that’s right. I’m going to close this thread - if you see any other behavior you’re curious about, go ahead and post a new topic.
