Negative comments are appropriate in this case. This looked so amazing, but the comments here point out the very important fact that this requires access to the internet to function, something that the co-founder so far hasn't addressed in the comments despite numerous requests for an answer.

The founder addresses this in a video review done by Tested. https://youtu.be/0R3mMUsHFvU?t=13m48s Also, I don't disagree with your comment, I just hate that the top comment always seems to put a damper on every truly promising launch or product - with Dropbox's launch being a famous example.

Tempering the excitement with some of the drawbacks is usually good.

Wow - Great way of generating Carcassone tiles. Thanks for posting. (Runs off to hackspace with files in hand)

Thanks! JavaScript manipulates the SVG files. That's one file type usable by the laser cutting machine. Due to how the machine operates, it's a mixture of vector cutting lines for the fine lines and tile edges, and bitmap images for the raster fill and shading. The vector lines are easy to change in color by adjusting DOM attributes, while for the fill images I change the colors on a pixel-by-pixel basis before spitt…

Very cool, I´ve seen other sell them:- https://msraynsford.myshopify.com/products/carcassonne-tile-...

Cool use of javascript.

It'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.

Yeah, recently purchased an ePaper dev module(electric imp). The specs looked cool and I wanted to get my hands on this technology for while. Well, surprise surprise the module can only be programmed via a web-based (cloud) IDE that connects to the device ... no other way around it. So basically if the servers are down, so is your device (in the case of ePaper at least). Not for me.

(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.

It is odd to require an Internet connection. The Epilog models at my disposal do not.

Every issue you mentioned apart from the terrible fumes are problems that already exist in one's home with cooking in your own home, and people, seeing the convenience of cooking in their homes, have adapted to it. Regarding fumes actually, the smell from my neighbor's cooking isn't always to my liking either, but, perhaps, burnt plastic might be worse and equally undesirable to all people.

I think one thing that was not clear are the fumes are extremely toxic. Rarely do you cook where the fumes could make you go unconscious or cause long term health effects. If you dont believe me, check out: [ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1475175/ ]

I guess that makes sense. I thought of the smell as nauseous but being dangerously unhealthy (than breathing the same concentration smoke from a fire, I'm assuming is the comparison) makes it involve different levels of health issues. I'd suppose they'd have to make the buyers sign waivers, huh, otherwise they have a number of civil class-action suits waiting--from which they lose anyway since a waiver would make the cutter much less attractive.

It's a very polished product, and the "pen" mode is a cool idea. To me, they're targeting an odd demographic, Makers who can afford expensive toys / tools, but also want a very friendly, hands-off interface. I would have expected the Maker camp to be ordering ~ $700 40-50W laser cutters from Shenzhen. I suppose the Glowforge would be pretty great in a school setting, though.

CEO/Founder of Glowforge here. There are a bunch of lasers billed as 40W on ebay and amazon, but please look really carefully before you buy one. The mostly-harmless part is the lousy interface, overrated tube, and inability to cut (the motion controller only supports raster mode). The worrisome parts are the ungrounded case, high voltage wires that are usually but not always firmly attached, and lack of an interlock…

Can you talk a bit about the tube? Is it DC or RF excited? Who is making it?

This is a pretty neat product. I especially like the continuous-feed idea. I'd really like to do stuff that involves stainless. What would be the cheapest option capable of doing some reasonable sheet stainess? My wallet is cringing at the mere concept, but maybe I could talk a local hackerspace into doing it or something. I've been meaning to build a CNC mini-mill for a while. I think that seems like a more practica…

A CO2 laser will not cut stainless - it won't even mark steel unless you coat it with a special ceramic. You're looking at a very very large fiber / YAG laser to cut it. A low power YAG laser can engrave steel - commercially these start at about $30k

Technically, the statement "CO2 laser will not cut stainless steel" is not accurate. Stainless steel is commonly cut by 500W-5kW CO2 lasers, see:

https://vimeo.com/106264555

But it's true that sub-100W CO2 lasers are not even remotely capable of cutting steel.

Why hell would it need this? I would really like to know as well. Was seriously about to place an order for a Pro but this leaves me wondering...

Do you have any details about this? I can't seem to find that on their site. But yeah, if that's true it's a real buzzkill.

They say so here at 13:40 https://www.youtube.com/watch?t=292&v=0R3mMUsHFvU I said so in a comment half an hour ago, but it immediately got downvoted to oblivion. Meanwhile the comment seems to slowly recover. Nowhere on their website they say so. I would be really pissed if I bought a printer for thousands of dollars, unpack it and then realize I cannot use it. Letting it use my internet connection and being dependa…
