How is a 40W laser Class I, but the 45W laser is Class IV?

You can get Class I by preventing human access, I'm guessing the Pro can't have the same interlocks for some design reason.

I think the pro is 'feed-able', wonder if that's it.

In the video, at about 13:40 they reveal that to print you have to use the web interface which runs "On Googles Cloud". I would not like the interface to my own printer to be "In the Google cloud". Does that mean when the company goes out of business, the printer is bricked? And right after, they admit that they plan adding paid services. Oh oh. How will thesed paid services be announced? I can imagine how. Whenever…

Open source to the rescue:

Yeah, I just saw that on their youtube video; the sides can remain open during operation to allow etching/cutting of materials larger than the enclosure. That means human access is possible, so therefore the class IV.

I'm a maker. Tell me more about this $700 Shenzhen laser cutter? I googled it and I'm coming up with a few things, but only very small $400 units and very big expensive units.

Pretty sure they are talking about the K40 "blue box" laser. I have heard they require some mods to get working properly but for the price some think they are worth it.

More info please :)

This looks like a decent laser but I thought I'd post a few thoughts about this package which might give a potential buyer pause.

First, the main unique feature I see is the built in camera which apparently gives you a preview of cut/engraved finished part on your computer screen with the material as it's positioned inside the machine. This also (apparently, it's not clear), allows you to correct for misaligned material inside the machine. These are nice features, but it's perfectly possible to cut and engrave without them.

One big problem with operating this inside your home is the fumes. Now, they do mention that the base unit needs to be vented to the outside. What this means is that your neighbors (and you, if the wind is right) will have to smell the exhaust from this machine. It's not a nice smell if you're cutting acrylic. Though I personally got used to the scent of vaporized acrylic over time, your neighbors might not be so inclined.

So they also offer a $500 add-on ($1000 regular price) to filter the air so you can exhaust inside. The add on is smaller than the already small laser cutter. This is quite a feat and I would really like to know how they got it to work. You see, the fumes/smoke from a laser cutter can really clog up a particulate filter pretty quickly. Wood produces wood smoke, and acrylic vapor is quite sticky when it settles. So you have to have a powerful pump to draw the fumes through the filter. Then you need a good amount of activated charcoal to get rid of the smelly stuff.

If you look at the professional model air filters, they're $2000+ and you have to buy filters and media regularly.

Laser cutters get messy inside, so if you buy one, be prepared to clean it out regularly to keep the optical and mechanical components clean.

Problems with operation can START A FIRE, so be prepared to watch the machine 100% of the time while it's cutting.

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 or other safety precautions.

If you're excited about making a laser work, they're a worthwhile project. If you want to use a laser to make things, you probably want something that is closer to working out of the box. (Speaking as someone who shipped 770 lbs of laser from China, then spent way too long getting it to work... sometimes.)

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.

> you're not depending on Glowforge UI to be backed by a startups servers, the software runs on google cloud instead.

What? Who is going to pay that bill? For example, Glowforge goes out of business... Google isn't going to continue to host and maintain that software out of the kindness of their hearts.

> 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.

What does the UI being web-based, and "in the cloud" have to do with it's firmware?

For example, if the UI wasn't hosted on some google server, instead existed within the device accessible via WiFi (like a router) nothing you've said here would be any different... other than the user being able to decide themselves if they _want_ their device updated.
