Overview of this book

Until recently, Computer Numerical Control (CNC) machines belonged to the realm of heavy industry, but as technology becomes cheaper and smaller, these machines now can be used in home workshops. It’s not easy to get started, though, but thanks to this guide, you’ll be ready to take on a variety of projects in no time. A Tinkerer’s Guide to CNC Basics contains everything you need to get set up at home with computer-controlled machining and fabrication. Sparing you the theory, this project-laden guide helps you learn by doing. Once you’ve got to grips with the principles of CNC and installed the 3018 Pro CNC machine, you’ll gradually move from simple projects such as basic engraving to more complex milling and machining techniques. You’ll even learn how to upgrade your machine to accomplish more sophisticated designs. The plethora of projects in this book will keep you busy and give you the practice you need to get started with your computerized workshop. By the end of the book, your computerized home workshop will be one step closer to realization, and your machining skills will be taken to the next level.

With some common components, we can improve our machines’ performance and extend their capabilities. In addition, there are several add-ons that can be easily acquired or fabricated.

In this chapter, we will cover the following upgrades:

  • Adding end-stops so that our machine can home itself and not require us to set the origin.
  • Adding a Z probe so that we can define the starting point on any surface.
  • Giving your machine an emergency STOP switch so you can prevent problems from getting worse without having to rely on the computer and risk lag when telling your 3018 to stop. This is also important if you intend to operate the machine untethered from a computer.
  • Introducing the ability to carve and cut on a rotary axis.

We will also upgrade your 3018 to be able to operate as...
