Your recent e-mail said “internet access required.” Does the Glowforge actually access the open Internet, or do you really mean “LAN access is required?” I realize that files and commands need to be delivered to the glowforge via a LAN from some controlling computer, but I hope the glowforge does not require access to the open internet. I’m not too thrilled with the idea of a 40 W laser in my house that can be hacked remotely.
For the LAN, does you infer that the Glowforge is WiFi only, with no wired LAN except via an “adapter,” which I assume is a WAP. This is not terribly secure. Please consider adding a wired LAN interface and a way to disable the WiFi.
