Your 3D printer needs a handful of electronics to control the Extruder and motors, and that's what you'll be working on in this chapter. While you could easily mount all of the electronics on a separate piece of plywood, that would also involve having many long wires running from motors and Extruder to the various controller components.
Because most of the electronics for the 3D printer are small, you can mount them right on the 3D printer frame. This will keep the machine portable but also help to reduce the clutter that comes with lots of long lengths of wiring.
