[edit] Overview

"Mendel" is the name for the second generation RepRap design - it's a self-replicating 3d printer. We're going to make a Mendel using the MakerBot. For more see: http://objects.reprap.org/wiki/RepRap_Version_II_%22Mendel%22

[edit] Updates

[edit] March 23

Dave cut some threaded M8 rod to length and mocked up a frame side using that and the printed frame vertices.

[edit] February 2

Heated build platform working well. Created a Flickr set for this Mendel: http://www.flickr.com/photos/dave_menninger/sets/72157623332559510/

[edit] December 18

MakerBot parts came in today! Now we have RepRap board, extruder controller and 3 stepper controllers. (still want to test James' design as well)

[edit] December 13

Electronics were in stock at MakerBot.com for less than 24hrs. Ed squeezed in an order for the Gen3 kit (separate components were already sold out) although we want to use James' circuit board for this when he's ready for testing.

Ed is seeing if a friend can fabricate a couple of these babies out of aluminum:
