The Electronics

Abstract

Your CNC machine consists of two parts: the MDF (and the bolts, bearing, nuts, and other hardware) and the electronics. The majority of the chapters in this book will cover the building of the CNC machine—cutting, drilling, and bolting together various MDF pieces to make the physical frame of the machine. The other part of the machine is the electronics. Three motors will be used to move the router and allow your CNC machine to do the job you want it to perform. These motors are controlled using some additional electronics, which we’ll talk about shortly. It is these electronics that will connect to your computer and receive instructions from the special software you’ll be using to tell the machine where to cut, drill, and perform other actions.
