While most of what you’d think of as “features” come from the cloud, there’s a lot of important plumbing in the firmware, like the experience for getting your Glowforge up and running online for the first time, the coordination of various hardware components, the drivers, etc.
Each Glowforge is on a “channel” that determines which firmware it gets. We have the ability to put different units on different channels, e.g. one for beta, one for in-house, etc.
No plans to announce on what we’re doing with that yet, so file it under “interesting trivia” for now.
