    So the "uP" GF refers to is, what, duct-taped to the inside of the cover? Pick a story and stick to it.
    Not a traditional control board. If you want to debate semantics and tell them that they are wrong, here's a link to get started:

    http://community.glowforge.com/t/skydog/1668/22

    Here's an excerpt:

    "The glowforge does not have a motion controller onboard
    How does it move then? It may not have motion planning, but it must have stepper control of some kind inside. I can't imagine it solely has an h-bridge being controlled over the internet. Stepper control etc must be local, otherwise network latency would cause total havoc...

    Traditional motion controllers (GRBL, TinyG, Smoothie, Marlin, LinuxCNC (or MachineKit) & Mach3 all have the ability to output stepgen pulses required to move the steppers (specifically to tell the stepper drivers which direction and how long). The glowforge does not have this. The Glowforge 'cloud' create these and outputs a waveform in which the glowforge 'plays' locally."

I do not think that could even be implemented if the wireless feed was in the next room let alone over the real internet. Anyone who has worked with, repaired or built CNC knows it depends on constantly knowing where the carriage, milling head or laser is at and sending reliable feedback to the controller. Yes I know steppers do not have feedback, but it depends on knowing the last command was received.
    Right. Steppers do not have feedback. It's open loop. Check out that link above.

    The GFs hardware buffer contains the motion planning (performed in the cloud) which the onboard motion controller then does it's thing. The "uP" is the motion controller.
    There is no traditional onboard controller.

    You do realize that the two paragraphs you quoted contradict each other, right?
    Yoga class makes me feel like a total stud, mostly because I'm about as flexible as a 2x4.
    "Design"? Possibly. "Intelligent"? Sure doesn't look like it from this angle.

    You might need to read the thread to understand the context.

    I think we need to start a new thread just for all the problems that the people that got their Glowforges are having. Can't use the whole bed, takes hours to calibrate, can't engrave large files without breaking them down, server is down, takes hours to engrave items, camera does scan correctly and can't through cut what they sell as Proof grade at high prices. There are more problems but you get the idea.

    Probably confirmation bias, on your part.

    I suppose you could start another thread, if you like.There's already a Problems and Support forum over at GF. I clicked this last quarter, when most of the shipping has happened, and then sorted the most viewed threads. There doesn't appear to be one thread from that forum on the first page. The most popular threads are from the Made on a Glowforge forum. The FB group seems to have received the machine pretty well too.

    Just the opposite in many cases Matt, a lot of first time users are making the mistake of comparing the GF to nothing else.

    Even the worst machine tool in the world will seem better than no machine tool at all
    Poof! and just like magic the shop keeper dissappeared

    I see there are hundreds of posts in the Problems and support forum and a lot of them are closed before they are addressed

    Glowforge forums are heavily moderated, makes the CIA look like an open group.

    In all fairness to GF, that's the method they use for one leg of their support. You can email them OR post it in the support section. If you post it in the support section, they lock it when it's been logged into their support system. It's not locked because they don't want people posting, it's because it's how they setup the support forum. Post, when we see it, we'll acknowledge it by locking it. Makes it look like they just lock anything with a problem, but that's not the case at all.

    Locking and removing unwanted Threads make it look like Everyone is Happy!! I suppose someone will start a Forum like the other not popular co2 engraving machine had, where un-happy owners could go to complain. I swear Matt is being paid to act as a GF advocate on this Board.

    I don't agree with that and don't see it to be true. It's also why I sorted by views, which can't be locked. See previous post. Also, GF doesn't have admin of the FB group where the general consensus seems to be that they are happy with their purchase and enjoy making cool things.

    GF just moved the counter to indicate that they are shipping day 30 of the the 30-day campaign Pro units, which were the most popular. Posts have indicated that the ship dates for some have moved up, in the right direction.

    Good point.

    Well, of course, you have no proof of this and I don't even recall an owner claiming that a thread has been removed or censored. This is a provacative tin-foil hat theory that you just made up. No matter how many times you repeat that, it will not make it true, only repeatedly wrong. You have no interest in being correct, only right.

    If you have a beef with GF's marketing hype or name, but OK with creating falsities, you might need to consider the hypocrisy.
