Once I had the mechanics down, I had to wire everything. I am not skilled with programming Arduinos, and I wanted to keep my wiring skills strong, so I decided to wire it all directly. I wanted to motorize the X axis since the 10-32 rods made it take forever to move the axes by hand and the X axis has a really big range of motion. I got a three position switch so I could have the motor move one direction, stop, and move the other direction without the aid of a controller. I also wanted the spindle to spin with a different switch, but not necessarily change direction. My messy wiring planning is below.
