The 2BEIGH3 (pronounced "2 by 3" ) is an R&D machine that can quickly be modified from 3D Printer to CNC and back with very few changes and in less than 1/2 hour.
The 2BEIGH3 was released May21, 2012 and received 52,000 views in just 70 days with over 180 public comments and 1,700 private questions and comments.
While the design posted on the instructable site was a basic CNC and 3D Printer configuration, the actual 2BEIGH3 used by taulman has many more configurations and capabilities. The intent was to be able to test, measure and print anything within reason and not be limited by a machine.
The 3D Printer section of a 2BEIGH3 uses high torque NEMA23 steppers, Modified Stepper driver boards to handle high back-emf, a Z axis with a 1/4-20 threaded rod on a shimmed ball slide, two types of extruders, the largest, capable of 80-120 lbs sqr/mm and several hot-ends with some capable of very high temperatures as well as some designed with multiple orifices to reduce oxygen uptake during heating.

Because the instructable was very large, there may have been CAD drawings that were to large for the site.
Some of these can be found here in native Rhino Format.
