I agree with this 100%. We all understand that people posting videos aren’t making glowforges…but 3 - 6 months is a long time to wait for a $2500 item. I think if you don’t post something every few days to keep people interested…and to prove that some of the features you are talking about actually work (ie. two sided cutting), that as the next 2 - 4 months tick by, you are going to have a lot of people backing out and wanting refunds. Especially if another company comes out with a similar product in the next few months, who can offer delivery sooner.
Just my two cents. You have our money, because you made claims, and gave us a glimpse… and by holding our interest, showing us every few days, something worth seeing…(as the original poster said, perhaps take requests for materials to cut, etc)…that is what will allow you to keep that money.
