I realize that the GF operates via wireless only. I’d like to know if it can connect to a tablet via wireless router, and utilize that tablet’s 4G connection to connect to the cloud. Or would it be something more roundabout, like the tablet creating a hotspot which the GF connects to? Seems like the former option would be superior if possible.
I believe that any reasonable path that gets the Glowforge access to the internet should work. At the very least, the direct tablet hotspot -> Glowforge will work as indicated by @dan here:
It would actually be easiest turning on your tablet’s wifi hotspot, if available. Less monkeying around with trying to connect a wireless router and using your tablet as the gateway. One less point of failure for networking. Less is better.
