I don't know how big you think that trinket is, but that etching isn't even close to 1/4" deep, more like 1mm-1.5mm. Unless of course you think it's 1" thick overall, in which case I'm curious what power laser you think was used to cut the outline.Originally Posted by Bill George
I also had a CNC router that would do that piece...if it was the size of a dinner plate. At the small scale this was done, even sub-millimeter bits won't leave corners that square, and it would take forever.

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

Yup, it requires high-speed modulation of the laser power across each raster scan.

Yes I had a small Servo motor router and with VCarve Pro and some tiny milling bits I could engrave with it.
I have no idea from looking at a picture how big the subject? You must have better eyes than mine. I am looking forward to someone posting one they have done?

Somebody please tell me how to control charring color. Creating light colored char and dark colored char in different areas that are engraved at the same depth. Within the rings around the lasers / the ribbon behind the rings. The sun at the top / behind the ribbon at the top. The pebbles everywhere. Inside the logo at the bottom. Somebody Photoshoped the heck out of this thing.
I design, engineer and program all sorts of things.
Oh, and I use Adobe Illustrator with an Epilog Mini.

The FSL versions are no where near the quality Matt, the others are all RF lasers so have much better beam control and rise speeds
On the trinket I agree with Doug, somebody has photoshopped the hell out of that, look at the top where the spikey bits are, they seem to be above the height of the border ergo the entire border would have to be engraved away but it doesn't have a laser engraved finish
You did what !

In fact I'd go further and say I very much doubt that was produced on a glowforge

Uh, then why did you say the engraving was 1/4" deep? One clue to its small size is the blurring of focus at the top and bottom: lack of depth-of-field at short range.
Or maybe it's the size of a manhole cover, was CNC carved on a ShopBot, the charring airbrushed in after the fact, and rather poorly photographed...which do you think is more likely?

I would guess someone went over it with a qtip and alcohol post-engraving, selectively removing burn marks to make the engraving look deeper. They didn't do a real great job of it, but no PS was required.
Whether it was done on a GF or not... don't know, don't care. But there's nothing particularly difficult about doing this on a laser.

My point (again) is that no CNC router is required. And no, I'm not going to make a GF emblem to prove it: I have better uses for my time and there are more than enough examples of similar work on ULS/Epilog/et al.
(Note: I am totally agnostic on the subject of whether this was actually done with a GF. It certainly does not reflect any unique ability of the GF if it was.)

There are a lot of machines that can do this, thing is most of them are RF fired, DC tubes, even high quality tubes like GSI and Coherant simply don't respond fast enough to get really high quality engraving.

Sounds good but I personally doubt it was a Q-tip. Deep engraving MDF produces lots of char. The Q-tip would just soak the char into the porous wood. Plus I've never seen MDF engrave smoothly that deep. It's usually full of tiny pin-holes like the area around the small laser guns and to the left of the upper ribbon. I'm sure they took a pinch of the millions of dollars they brought in and hired a photoshop guru to "prettify" every image they put out.

Not gonna speculate if that image was of something produced on a GF or not, but I thought these were pretty cool:

It can be done if the machine is set up PWM rather than analog, most Chinese machines are set 0-5v trigger rather than PWM even though the power supplies can actually do it as can the control cards from Leetro, Ruida and AWC. I rewired one of mine to use PWM, it was a fun exercise but didn't really achieve much as I do very little engraving

heres one I tried way back when I had the fsl working.If I recall it took about 3 to 4 hours to do, and its not really good 3d . It looks more like steps then an even progression. This piece is about 3" x 4" x1/4" and its almost thru at the deepest points.IMG_20161213_114517001_HDR (Copy).jpgIMG_20161213_114453345 (Copy).jpgIMG_20161213_114545950 (Copy).jpgIMG_20161213_114554200 (Copy).jpgsorry bad photos but maybe you get the idea.

I've been able to see the GF at a maker faire, it can do that. The macro lens on the shot makes the work piece look larger than it is. It's a capable machine. More capable by far than a K40 though in terms of traditional work output no more special (I didn't get to see the camera tracing feature) than an import CO2 laser and certainly nowhere near any of the big three. The quality of the software is good but cloud based processing is still the weak link though it performed well. The issues over the life of the project have been hardware design, design for manufacturing and inability to scale manufacturing.
Software guys with a pretty good idea (easy to use laser engravers for non tech types) thought they could do hardware. By the time they added manufacturing and laser specific design staff to fix the initial design (not even a year ago) coupled with the inability to get a production line to scale without significant defects in manufacturing has led them to where they are right now. They needed to be somewhere like Foxconn or Flextronics and not trying to roll their own assembly with sourced subassemblies. EDIT: They have announced that Flex will be the CM. Flex makes Mac Pros in the US, the Xbox in China and Surface Studio in the same Texas plant as the Mac Pro.
It's not a scam, it's merely a poorly implemented manufacturing startup. They've got big names behind them in the second round so I'd bet there will be changes made in the management (they've already changed contractors) to be able to get the first run out the door. At this point I don't know what it means for them long term. The buzz is gone, the window has been missed and it's turned into a similar situation to what happened at Makerbot. If they miss the spring deadline there is a good chance they'll be done, particularly if there are a flood of refunds from the latest delay.
There are reasons they say "hardware is hard". Here's one reason the fits the situation at GF to a tee... http://lemnoslabs.com/2014/01/09/why-hardware-is-hard/
