I received the Glowforge Plus I ordered today, everything seems to be working fine but I noticed that the LED-lights inside the machine are off during the operation.
Take a look at where the ribbons clip into the wiring. The clip are towards the back of the lid. They may be a little loose and make the connection when you lift the lid but lose it when it’s closed.
Thanks for letting us know about this, and I’m so sorry for the trouble. Unfortunately, it looks like your unit is experiencing 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 just followed up via email to sort out the details. I’m so sorry about the bad news.
