I’ve had a Glowforge since 2017, as part of the original crowdfunding go around. After using it for a couple hundred hours over the years, I’ve kind of lost the passion for making and now just collects dust on the basement. I’ve got a bunch of birch plywood, as well, that I can send along with it. Looking for around $2000, but negotiable.
Welcome to the forum, but it seems you are on the way out.
Your machine is probably on borrowed time since it is 5 years old and the tube was estimated to last about 2 years no matter the level of use. Hopefully you will find a buyer.
