This has been linked to a number of times, but is buried in another thread. I figured it should have its own post.
If you ever find your GFUI stuck on this screen:
you can do the following to fix it:
- open another glowforge app tab/window with a different engrave. something simple. leave the other original tab open
- hit print, wait for the glowforge button to glow.
- cancel print
- go back to the original window
- error should be gone now
- hit print again on the original design.
if the problem arises again, just follow the instructions again…
