I fired up the device after not using it for a week. It cycled through the “Calibrating” routine at least 3 times (I assume this is a firmware update, but have no other way of knowing other than guessing based on forum posts).
I loaded in 2 very simple cuts on Proofgrade draftboard using (cringe) default settings, clicked Print, and received that message. I’ve cut these SVG’s before without issue.
It was around 7:20 PM EDT.
Strangely enough, the light on the Glowforge was blinking as if it was ready to print. I gave it a go.
It printed (cut) normally.
No further problems noted, yet. So, this is more to alert you to an issue I encountered, rather than a request for assistance.
