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.

Panels, cleaning, and access

At first glance, the three elements in this heading might seem unrelated, but in reality, they absolutely are. You want to have panels that open easily and provide maximum access to your work area as well as the controls on the machine itself. Of course, removable panels or a way to remove the entire enclosure for cleaning also means you have a way to control the spread of any debris that collects with each cutting job. Panels provide the means for ventilation and cooling you need to drive harmful fumes away from your machine and work area or let in air to keep your workpiece or toolhead cool. Also, with panels, if you are using a laser, make sure that you can safely view your machine in action without jeopardizing your eyesight. These same panels may also provide you with access to your emergency stop switch, power supply, and USB cables, and also confine any sparks or flames (should your workpiece ignite).

What you do for your enclosure panels depends...
