Pridate3D internals video. That is actually a very clever trick with the single belt that controls X and Y axis.

Great resolution on that.

If you want to roll your own variant of that single-belt X/Y motion, see http://www.thingiverse.com/thing:22005

This is a straight up hbot and does not do the corexy belt cross to counteract racking forces.

Good point; I hadn’t noticed that.

H-type belts are really cool! With a Bowden type extruder, all steppers are stationary on the printer and the weight is kept low. I’m working on a similar prototype: http://hipstercircuits.com/category/hipsterbot/

Looks like the entire printer is based on that CoreXY design, just with an h-bot belt arrangement.

i was going to build the same model. exact same system just with rods. i am afraid its patented or something

Karan, have you found a patent for it? If there is one, I’d be very interested in it. Festo claims to have invented it according to this article, but a Google search did not reveal anything: http://www.festo.com/rep/en-gb_gb/assets/pdf/Advanced_handling_article_IT_Feb_2013(1).pdf

its surely closed source and propitiatory.i am thinking of making it for commercial use. i dont know if i can do it or not.

Interesting to see that it’s an H-bot. They were carrying the X on the Y like MBI/solidoodle/etc. in the early version shown here: http://www.3ders.org/articles/20130325-singapore-pirate3d-aims-to-bring-affordable-3d-printing-to-the-masses.html
