It has happened to a few people, and support is generally very responsive in getting you a replacement. You should not have to pay anything for the replacement - but official glowforge support will respond to this thread - which, by the way, automatically opened a support ticket, so no need to email them separately.
While I know (as a fellow customer) how dissappointed you must be at this, hang in there - and do know that the (hopefully short) wait you will have for a replacment will indeed be worth it.
If you haven’t already spent a lot of time here on the forum, I’d suggest you keep reading. This is a phenomenal additional resource for all owners - and I can promise you from my own experience over the past several years, you will be very happy once you get your replacement machine.
Hang in there!
