Arduino Unicorn tester

I finally finished printing the Unicorn. I really wish I had gone for the two piece derivative, it would've been way easier to finish and attach everything!

I used the printable linear slide. It works so-so, but has a good amount of stiction... as do the rotary joints on the servo connectors... so I wrote up this quick sketch to let me run a burn-in test on the unicorn and try to loosen up the joints.

The goal of this is to allow you to test your unicorn WITHOUT an Extruder Controller.
