    What I’m wondering is when “Glowforge” will become a verb or adjective? Ie. “the marketing team at that new startup put out the most bogus information ever, they really glowforged it”
    I have done so much with so little for so long, that I can do almost anything with practically nothing...

    So many people are having trouble with uploading their designs and then getting them to cut on the material where they want it also when they have more than 1 of the same design to cut that they can't just hit as they say print a second time but have to go back to the cloud and redownload it. The other big issue is not being able to cut the full size that Glowforge claims as a working area.

    That 300 x 200mm is an interesting machine. Have bookmarked it. I do a lot of engraving on one of my lasers that is just 110 x 40mm and that Sinjoe could save a bit of workshop space when it comes time to replace my current machine.

    Email Felix @ sinjoe and tell him he has to be nice to you Ju

    You guys are essentially arguing over the definition of "motion control". You will never resolve your differences because you keep interpreting each other's statements in the context of your personal definition of "motion control" when that wasn't the definition that was used to formulate the statement.

    It's pretty clear at this point there is a cloud component that is is used to plan out the movement of the laser, and also some local hardware component on the GF uses that plan to generate pulses that cause the steppers to move. Whether you call the cloud component a "motion planner" and the local hardware a "motion controller", or the cloud component a "motion controller" and the local hardware something else doesn't really matter. If the point of the conversation is to communicate, agree on a nomenclature and move on. Call the cloud component "Alice" and the local component "Bob".

    Alice decides *what* needs to be done and delegates the implementation to Bob.
    Bob decides *how* to implement what Alice wants.

    So who is the controller? Alice or Bob? I think it's clear that you can argue it either way, though I suspect engineers will tend to say Bob, and managers will tend to say Alice.

    Anyone who is married will absolutely tell you that Alice is in control, Bob just thinks he is...

    When you hear someone misusing industry-standard nomenclature, it's a pretty good way to tell a manager is talking.

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

    I wonder what ink cartridge does take and does it print in colors like other 3D printers.

    That's not how the Glowforge works. The cloud sends down the pulses for the steppers and the Glowforge hardware just sends those pulses directly to the steppers.

    And that's the reason the GF will fail. Without a buffer file or a special file formatted to download the "Cloud" can not reliably supply pulses in real time error free. If you have any basic knowledge of CNC controls you will see issues involved.

    Are you sure about that, what is your source for that claim?

    In the professional machine control world, an industry in which I spent a majority of my career, there is no ambiguity whatsoever. If some amateur wants to redefine the term, they run the risk of sounding like an idiot. That is a situation that appears to apply in this case.

    So Art, I do not get your point? Is the GF Cloud sending down stepper motor direction and pulses or is it not? That is the question.
    Ditto what Rich said.
