[hackpgh-discuss] Re: opensource hardware meeting next week

I was going to mention this at the meeting last night, but I had other things come up.
I got in on the $98 dual extruder reward level, and it even comes with two high-torque NEMA17 steppers. We'll see how it turns on later this summer. Going to put them on my original design Prusa that I still need to finish wiring up the electronics.

What do you guys think about using this extruder for our yet to be built
printer?

There are "rewards" for both single and dual extruders with either
resistor or cartridge heaters. The dual extruder with resistor heating
is $98 - half the price of a Makerbot MK7 single extruder.

Looks like it would be compatible with pretty much every newer printer
out there. And should ship as soon as the the pledging period is over
(July).

    This is part of the reason I think it's not a simple question and
    actual experience with bots is part of the question.


        2 Comparing the pint quality of your first generation Cupcake to
        MakerGear's finely tuned sales tool demo unit is pretty absurd.


    Of course his first-generation Mosaic was "tuned", just like any
    production unit taken to a show by a company selling things.
      MakerBot, Stratasys, etc, would have also brought a tuned box for
    demos.

    However, my "first generation Cupcake" was hardly that.  It runs on
    a Mega, TOM/Gen4 electronics, beefed up replacement steppers from
    Lin, bigger power supply, and uses a Mk6 extruder with a custom
    temperature chart. About the only parts that are FG Cupcake are the
    case and the Z-plate and the fasteners.

    This is why I asked on the reprap-dev list something like, "which
    one is easiest to hack/modify/test for a club or school?"  The
    Cupcake was easy to assemble and turn on but modifying it has been a
    challenge for me some days given how many parts are stuffed into a
    tiny wooden box.

    I'm willing to at least look at MakerGear's products and designs
    having seen the effort he puts into cranking out a good product.
      Personally I don't see much "hate" for him on the reprap-dev list
    and there are plenty of MakerGear parts on Thingiverse and the M2
    has some promise. Sure, MakerGear is selling Reprap clones (and a
    bunch of other stuff), but it's in a very competitive market. If you
    look at the lists on reprap.org <http://reprap.org> and on ebay he
    has lots of competition from everyone from grad students to "Chinese
    pirates" as some describe them.
