Dan's story about making a wallet with the laser is amusing: https://www.youtube.com/watch?t=292&v=0R3mMUsHFvU "No, I have a laser!"

A bit off-topic, but you gave me an idea: What if Google did guarantee to host stuff forever when startups go out of business? It would eliminate customers' reservations in cases like this, and hence eliminate business reservations about going all-in on cloud services. The increased business could potentially more than cover Google's cost. The trick would be the care and feeding of the software. But as the industry m…
No it wouldn't. I still don't want to depend on a remote service to use an alliance this expensive. Internet connections can be unreliable.

Have some cartridge of CO2 inside that is getting released in such scenario? There's not much volume inside so it should do the job. IANAF, just wondering.
For a while I've been wondering if you could flood the chamber of a laser cutter with CO_2 routinely, not just to prevent fires but to prevent the scorching that laser cutting leaves on wood. If that would consume too much CO_2, would it be workable to instead spray it topically onto the point of the cut, a bit like the inert shielding gases that some forms of arc welding use?

Yes. Actually both intake and exhaust fans. Both of those are under software control, so they only run at the speed required for the job. Then the $500 air filter option has its own internal fans to assist with air, also under software control. If you use the filter, there's nothing else hanging off the back of the device except a power cord. (My old laser had a squirrel cage fan, an aquarium pump, and a chiller teth…
Whats the ducting capability on exhaust? Munching on wood with an Epilog laser will produce copious volumes of smoke, and the air assist and 400CFM blower are not trivial pieces of equipment to embed in a unit to properly quell any fires and actually extract all the air needed.

Good question, I _think_ the ideas is the exact opposite -- you're not depending on Glowforge UI to be backed by a startups servers, the software runs on google cloud instead. Pros and cons, obviously, but I think the main pro is (like a Tesla) the machine's performance and usability can be improved without you installing any new software. As far as dependencies go, google's probably the best possible choice.

is likely referring to them updating their cloud infrastructure, not the machine. By centralizing the processing and whatever else, they can ignore some local machine updating.
Its not worth the massive drawbacks, but its likely the truth wrapped in that marketing speak.

(founder/CEO here) I vented a 60W chinese laser out my window for a year in the suburbs, but I've learned never to underestimate what neighbors may complain complain about. The air filter is definitely a good idea. If you do the math on the volume, and compare it to the actual volume of the filter of e.g. a Purex, you'll find it's similar. Almost half of the volume of the Purex is in the fans or open airspace; we hav…
Is it true the machine requires connection to internet or your cloud to cut or engrave? I was about to order a Pro until I read this in the comments. I expect to be able to use this machine with my laptop running some program and "send to laser", no internet connection required.
The Glowforge does require a cloud connection to operate. We use cloud vs. local a host of reasons including the motion planner, alignment, image recognition, and faster feature development.
But based on the excellent point made here that nobody wants a paperweight if we fall off the globe, we decided to make a change. We're going to do a GPL release of the firmware so people can do whatever they want, including porting offline functionality. You buy it, it's yours, you should get to do what you want with it.

Thanks for the great feedback.
Re: Glowforge launches consumer-grade laser cutter
#189It's not just cloud connected, it's cloud dependent. It requires internet access and their cloud services to function at all. That's kind of disappointing.

Air assist is a classic thing on many decent laser cutters, especially for the reasons mentioned. On our lasersaur for example, a builtin air nozzle blow compressed air at the place where the laser beam hits the material being cut...
