    I know two Makerfarm i3v owners and they were very happy with their machines and the company.

    The Pegasus is a very weird mix of wood and metal. I guess it shouldn't be surprising given how much...

    Can a user post some sample scans and impressions of this design? I can only find one video of scan results, moving about a point cloud on YouTube. No printed objects, etc.

    Those motors have a lot of tiny little plastic gears inside. That's most of the reason why they're cheap. I wonder how long they'll really hold up, even with the dialed-down performance settings.

    It would be nice if they made their dev boards more widely available. It would be nice to have another option. Integration into a locked-down machine doesn't sit well with me though.

    Well, their brand PR is one of the more annoying ones. It's not just about this article.

    Also, you could "lost PLA" cast parts too. I've known someone that's successfully done it, though his early efforts were a bit rough.

    The story does link to it, though I think it falls a tad short of attribution. Sure, you can go find the file creator's name (ericthepoolboy), but not naming him still seems pretty weak.

    Yeah, I'm thinking it's not even pretending to be generous for the marketing. It's just straight-up quid pro quo.

    I'd suggest not buying their machines anyway. The machines and materials cost a...

    I didn't do any calibration, though I did check it against a separate thermocouple meter.

    Specifically, I used a thermocouple on an E3D, and B3's 500˚C thermistor on a Pico.

    "over 100 hours of testing" Is that supposed to be a lot? Is that divided between all six prototypes, or just one long part build?

    If it's all-metal, why does the barrel look like plastic?

    An external radiator is needed, but I gather that's standardized in the PC water cooling circles. And this seems to be made to appeal to them.

    As it is, I do question the need for this. Fan...

    I think you'll have to ask them. I didn't look very hard, but I don't see where they say what's actually in the M3D, what protocols it uses, etc. The web site claims the software and instructions are...

    Yes, in my experience, threats to sue are 99% empty. The fact he doesn't respond to a serious inquiry suggests he's not serious. Also, if you're not in Texas, Texas law doesn't apply to you.

    Did they say how they got the filament? Did they extrude their own? 14kg spools of PLA don't seem to be very common.
