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.

The ShapeOKO

Long ago, I purchased a kit for the ShapeOKO 1. At the time of this writing, they are on version 5 of this machine. This unit is more a “pro” unit that goes beyond the desktop hobbyist but is still small enough to occupy a suitable spot on your desk (albeit, more space than the 3018). The ShapeOKO 1 used belts for movement, using all-metal components. I outgrew mine almost immediately, and it has sat languishing and waiting for its upgrades. The new versions of the ShapeOKO have features that improve rigidity and accuracy that we have discussed elsewhere in this book, such as rails and ballscrews. I will eventually modify mine to use leadscrews and rails and replace the current contrller with an updated controller, or convert it to a purely laser platform. The ShapeOKO is expensive when compared to our 3018s, and the jump in cost is significant. However, it is a more “serious” machine, and if you are doing more than hobby work, this machine...
