So I went to print an item last night. First time it’s been on in 2 days. Got a min into it and heard a pop and no power. Outlet works, don’t have a cord to try. Waited over night and still don’t come back on like some have. Any ideas?
Yeah, unfortuantely, you’ll probably want to unplug it and wait to hear from support. (Sorry.) 
Oh no! I’m so sorry your Glowforge is no longer able to turn on.
Unfortunately, this is an issue that we can’t resolve remotely. I want you to have a reliable unit, so I’m recommending we replace this one. I’ll be in touch via email to sort out the details.
I’m so sorry about the bad news.
