OK, forgive me for going slightly off-topic here, but this whole time, I've
been sitting here wondering if you're batshit crazy, or if your 3D printer
design will work as well as you say it will work.  That's mainly because I
do think it's crazy to be designing a machine in 2017 when there are so
many existing designs out there that work.  I remember your arguments from
before as to why, so my purpose of writing this isn't to bring the
motivation back up.  Originally I didn't really have a leg in the fight,
but as I've been looking at the CAD screenshots and build pictures from
your recent work, it is actually starting to take the shape of something
that I had started to design about a year or so back, for the purposes of
SMT pick and place.  Looking at the pics at
http://forums.reprap.org/file.php?177,file=96492 and
http://forums.reprap.org/file.php?177,file=96491 it looks alarmingly
similar to what I had originally intended to design.  The only differences
are what gets mounted on the head, and I probably would have went with
Hiwin rails instead of pulleys.  There's enough room on that head for
cameras, a Juki nozzle or two, and a height touch-off probe.

Differences in 3D printing philosophy aside, I think that this design could
possibly be useful for an SMT pick and place frame.

At this point I'm just going to sit here and patiently wait with popcorn in
hand and wait until the whole thing plays out.  I'm not in any real rush so
it wouldn't even be in 2017 before I would start building one.

Anyway, good luck with the whole thing.  I still think you're batshit
crazy, but in some evil genius way, if you can pull it off.
