Slic3r has experimental support for dual extrusion with a dedicated head
for support material.
Dual extrusion is nice and these extruders look like they could make it
much easier for RepRap printers.
Thanks,
Matt

Background:
I have a Mk7 right now and I am not happy with it. The tension
system is such a joke that I replicated the Mk6 adjustable tension
system on the first day. Since then it's repeatedly jammed, when i
talked to Mets about it he thought there might be some tiny
scratches inside the extruder. I bought some .35mm and .4mm drills
to try and clean it up or make a new extruder nozzle.
Right now dual just gets you two colors, not a pro-level supporting
system for making complex prints. So while this dual looks cool,
I'd like to see a bunch of other people using it without any problems.
I've just spent way too much money on parts and designs that failed
early on as there had been no field testing.

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).

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>
<http://reprap.org> and on ebay he
has lots of competition from everyone from grad students to
"Chinese
pirates" as some describe them.
