Looks great, are you planning to publish the parts when you're done? I'm sure folks would find it quite useful as 8mm rod & bearings are quite a bit more common than 6mm.

Yes, I definitely plan to publish the parts. Once I get the kinks worked out, I'll figure out the best place to publish them.

What are the profiles size? 15x15 or 20x20? 20x20 is far cheaper than 15x15 at least here in Europe. You can get 1m for only 4€ which is about 5 USD and they are widly available.

RepRapPro does this with two Melzis, which are quite similar to Sanguinololus. You would have to do a bit of research and looking through RepRapPro's firmware, but I think it should be doable with two...

They're designed for Misumi 20x20 extrusions, which were $4 each. The rods came out to about $10 each, so they're a much larger part of the cost than the aluminum extrusions. I order the rods and...

I'm working on the mounting brackets for the end stops, and I have a question for people. RichRap used hall-effect sensors, but reading some of the posts on this site, it sounds like micro switches...

Awesome design, thanks Richrap. I have most of the BOM ordered now. One thing that worries me: When I ordered the printable parts, I left off the list the LCD covers. I was planning on printing them...

Nicholas, It looks amazing, I bet there is little to be improved. The gear joints add something special to this machine, it looks like nothing else I´ve seen, like more industrial. Congratulations to...

Thanks to you! If it wasn't for you I would be stuck with torsion springs. Let's take this all the way. BTW, You could do all 3 DLCJ's and the 1 PGDJ for one arm with one string. It could suck to...

(This relates to the arm idea shown in the September 11, 2013 10:47AM post. That's the post I clicked "reply" in!) I don't think this 2-joint arm scheme works as-is, because the string headed for the...
