Care to actually address @jason.fuller0’s issue? How about “A purple button indicates {cause} and since {change} it’s no longer indicated so it turned off.”
Maybe I’m the only one, but I’d sure like to know what it means, how to avoid it, and how to resolve it if I encounter it.
Purple buttons are quite rare and indicate that your Glowforge needs attention. If you have one that remains after a reboot, just give us a shout if you see one and we’ll investigate.
