That is excellent,

I didn't realize it, bit you're correct, there are fewer non-printable 
parts on a scara versus a conventional XY platform. (no linear bearings)

That platform (video) looks really far along. One of the mechanisms IBM 
used in this arm to maintain constant direction on the front facing 
appendage is just link it with a belt to the theta 1 axis. it 
effectively removes the 'turn' on the front axis, so you don't 
necessarily have to have the extruder (or pen) in the video's case in 
the exact center of the front facing part. I can snag a picture later on 
to demo this, which might be useful for printed-out-scara-arms.

@jeshua, thanks! The smiley-face was a reference to the movie 'moon'. 
There's a robot in the film with a very basic display, that looks 
similar to the printout.

I think this is the most-recent for scara-reprap development:
http://forums.reprap.org/read.php?2,128991,128991

if you run into other people developing for that platform i'd be 
curious,

Thanks,

Re: [Emc-users] SCARA robot arm 3D printer

[ceenbot]

This link is for a reprap SCARA: http://www.youtube.com/watch?v=Cquw7dvR80A

There was a conversation a while back about how many plastic Yoda heads and 
other fast prototyped plastic waste would end up in land fills.  I see the 
above reprap SCARA being a positive and constructive engineering use for a 
reprap machine.  The HF06 used stepper motor and linear bearings but the rest 
is pretty much made with a reprap.

Cool stuff.

Thank you Dane!

I am going to hold off on my purchase of the Makerbot extruder controller for 
now then!

P.S.

I love the happy face on your machine!!

Wow, that is a really great idea! Pretty much the only thing you couldn't print

This is an interesting development, as it has more printable
components than a conventional RepRap. You could (in theory) print the
arms, whereas printing linear slides is more tricky.
