You are definitely underselling the performance. I said it when you released the primo, and I agreed with your rationale for doing it, but I’m saying it again. And I think you’re doing it while certain others are implying that THEIR machines are everything a cnc should be.
I think, even if it’s the designer/engineer/head-marketer/sole-proprietor making the claims, video is video, results are results. You can make flagship videos with known specs and construction to show what’s possible as advertised and disclaim and end-user’s mechanical abilities, printer squareness, pla quality, tubing straightness, or whatever, then point to a repository of community videos (like your YouTube playlist).
Tests are well and good, but where the glowforge gets ahead (imo) is showing projects being made and convincing viewers that they TOO can make things with the push of a button and sell them for thousands of dollars in their own side business. I don’t like the idea of convincing people they can do a thing, but it would certainly be useful to show the things that are being made by other people. A curated collection of generally useful items to start with, and maybe some general instructions that could serve as an intro to cnc and/or design would be a useful reassurance to new users, too. Like “At the end of this project/series” you’ll be able to do xyz".
