I’d do it that way too (more reliable), but here’s the thing: we all already have our Glowforges. Unless there’s already a plug or an IR connector on the bottom of all of our units, they can’t communicate that way. I don’t recall seeing one, but I could have missed it (I only looked at the bottom briefly) and I’m not turning my unit over to check (anyone have their GF on a glass table? If so, post a photo!). I do know there are no connectors on the back of my unit. Given how clean their design is, I can’t believe they’d send us all a kit to retrofit a connector on our units when we get the air filters.
Funny thing about that aluminum can experiment. Shift your weight and the can collapses. If you’re not careful, you can break an ankle. Imagine the weight of a Glowforge shifting as you take the crumb tray in and out, when you put in heavy material, when the laser’s moving back and forth.
Again, all of our units are already out in the field. They’re not changeable and they seem to be designed to be supported exclusively by those two long feet. Maybe the feet only need to be supported at the ends. Maybe only at three points and the rest is cosmetic. Maybe the unit is designed so that it can be completely supported from the perimeter instead of the feet. Nobody outside Glowforge knows unless they’ve actually done stress tests. So, sure, it could be completely open in the middle, but I’m still going to say it’s doubtful given what we do know. That said, it would be awesome if it was open enough that the filter change was quick and easy to do while you have a couple of people lifting your unit up.
Please @dan, enlighten us!
