Delteron

Hey folks! I'm back again with another printer I'm designing and building. I'm cheekily calling it a Delteron, but it is one of the 2 other configurations of a Tripteron. This one is colinear, and uses a Linear Delta type frame and actuator orientation. I am still refining some pieces so I wouldn't recommend attempting to build this yet, but it *does* work, and has linear kinematics like the other Tripterons. It is **not** Cartesian, however, and requires custom code to pre-process gcode or to make your firmware of choice drive it.

I've written the code for Smoothieware [here](https://github.com/Apsu/Smoothieware/blob/edge/src/modules/robot/arm_solutions/ColinearTripteronSolution.cpp) and it can be readily adapted to other firmwares, I'm sure.

Bill of Materials will be coming once I am a little happier with the joint design, though I believe these models are very close.

As before, lots of information on the RepRap Forum thread, starting with this post [here](http://forums.repr
