GUS Simpson is a experimental grounded delta robot 3D printer prototype, built in 2013 by Nicholas Seward in Hot Springs, Arkansas, USA. Simpson is named after George Gaylord Simpson who came up with the idea of Quantum Evolution, the theory that evolution can happen in abrupt burst. The name signifies that this is a quick divergence (idea to first print in 1 month) from other existing designs.

Your choice. Currently gcode is transformed using a gcode preprocessor and then sent to GUS Simpson. I use Repetier for machine control.

Assembly
One of the biggest gotchas is that all the holes for M8 and M3 bolts will probably have to be drilled with the exception of where you actually want to thread into the plastic. The other gotcha is that you will probably not be able to drop the 608 bearings into their holes. I put the part in an oven on low. I take it out every minute and hit it against a hard surface. When the tap turns to a thud you are ready to insert the bearings. I have heard reports that you can do this also by heating a bearing with a hot plate or heating the part with boiling water.
