Laser Class definitions are a measure of beam safety not overall machine safety. The class is defined by the ability to access unguarded laser beams nothing more.
A 1mw 532nm Green Laser pointer is safe according to it's Class I rating...right up until you shine it into the cockpit of an aircraft

Oooooh. I just got an email from a company called Trackr. They make little keyfob like devices designed to help you locate lost keys and wallets and pets and whatnot. Their email says they have teamed with GlowForge, advertising that you can now customize your Trackr with your GlowForge in your own home!!! (seriously!) A deal! I can buy my $17 Trackr and by adding a $1700 GlowForge to the order I can use the GlowForge to customize my Trackr!!! As they might say in the UK Dave...."Brilliant!" <grin>
Where is that credit card????
900x600 80watt EFR Tube laser from Liaocheng Ray Fine Tech LTD. Also a 900x600 2.5kw spindle CNC from Ray Fine. And my main tool, a well used and loved Jet 1642 Woodlathe with an outboard toolrest that helps me work from 36 inch diameters down to reallllllly tiny stuff.

hahahahha I guess I've got cynical over the years brother...my old Dad taught me "If it sounds too good to be true it very usually is" and sadly in this case I think he's right

Well, goodness -- anything can be misused.
What part of this is not true?

What class are the machines already in schools?

Big difference in a school and a kitchen table. You don't have a 4 yr old sister next to you at school where an adult is always present.
Lasers : Trotec Speedy 300 75W, Trotec Speedy 300 80W, Galvo Fiber Laser 20W
Printers : Mimaki UJF-6042 UV Flatbed Printer , HP Designjet L26500 61" Wide Format Latex Printer, Summa S140-T 48" Vinyl Plotter
Router : ShopBot 48" x 96" CNC Router Rotary Engravers : (2) Xenetech XOT 16 x 25 Rotary Engravers

I through IIIb usually although it's the suggestion that the machine is "Safe" per se....that generates a system of acceptance that accidents cannot happen.What class are the machines already in schools?
Most blu-ray players have a 1.5 to 3 watt 445NM diode...the way they are constructed means to get at that diode and cause harm with it is close to impossible (the cartridge is sealed and the drivers are linked on a ribbon cable) so the chances are you would have to be quite skilled to get to the bit that can do harm. Not the case with a laser, we have no blink reflex to the 10,600 wavelength so any minor accident can be serious right off the bat.
It's the potential harm that is the problem
A handgun is safe..it's an inanimate object so much so that millions of good Americans own them. By the same token and test a W53 Nuclear Warhead is also safe right up until it isn't. Then potentially millions can die.
What I'm saying is the test of safety isn't a valid comparison,no more than comparing a Glock 17 to a W53.

OK then.

A thought just occurred to me. The Glowforge cuts out flat parts to construct a 3-D object and they call it a 3-D laser printer. Does that mean a 4 X 8 CNC router is a 3-D cabinet printer?

Eh? That power sounds high by a couple orders of magnitude. Milliwatt maybe?

"Design"? Possibly. "Intelligent"? Sure doesn't look like it from this angle.

Trying to figure out what problem that actually solves...OK then.

I'd be a lot more impressed if they released the cloud/server-side stuff under GPL, but that ain't gonna happen. If the as-bought machine requires "the cloud" to run, having the source to the firmware doesn't make it run if the cloud-based portion goes bye-bye, it just gives you the theoretical capability to spend a lot of time and money modifying the firmware to run standalone. In the meantime, your Glowforge widget (and all the others) is a rather expensive paperweight.
(That's assuming you know quite a bit about machine control, firmware/software development, etc. As it happens, I do, and I wouldn't touch that job without at least a 6-figure budget.)

Blu-ray laser diodes are fairly powerful. The ones I've seen are 700 to 1,200 mW. I'm skeptical that you'll find 1.5 to 3 W diodes in common blu-ray players though. A quick search for a 3W diode results in finding one on eBay for almost $500.
