Preface: This article is in progress and should not be used for any wiring or troubleshooting. There is a high level of information contained in this article.

Depending on which machine and control board you have, the wiring for your rotary may vary. Nova (7pin), Odin, Bolt and Aurora 2.0 all share the same rotary wiring. The Aurora 1.0 wiring was Gnd Reference signals, so some wire changes have to be made for the same Rotary to work on the different machines.
