I’ve looked at your post history, and it sounds like you’ve been having related issues for the last few days.
Something I’ve noticed is that many of the Glowforge that come out of the box seem to immediately require a firmware update, and that’s the first challenge. I suspect that, by now, you’ve already received yours, if you’ve have a stable internet connection.
But the other issues sounds a lot like you might be suffering from poor Internet connectivity with the Glowforge in general, for one reason or another. I think your best course of action is to make sure you have a strong wireless connection in the same room as the Glowforge, taking whatever measures are needed to accomplish it. The rest of it – repositioning the gantry directly underneath the overhead camera, for instance – would hopefully fall into place thereafter.
Disclaimer: I don’t have mine yet, this is just general information from reading other’s efforts.
