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.

Chapter 11: Building a More Capable CNC Machine

Summary

In this chapter, you have seen a design for a versatile type of purpose-built CNC machine that runs faster than a 3018 for laser cutting and plotting. The same machine also can be applied as a drag knife cutter. Because this is a belt-driven machine and the toolheads are very light, they can operate much faster than the 3018 for these functions. That is not to say that the 3018 in all those modes doesn’t work, but you get added utility and the ability to run parallel, unrelated jobs rather than tying up your machine to run those same jobs in series. More importantly, this kind of machine can have its work area adjusted by simply changing the dimensions of the two larger extrusions. The limit to this is how much the machine can take the way it is without tipping over (the Y-axis mount stabilizes it). However, I built a machine recently that adds a second 2040 extrusion, feet, and X-axis carriage that supports the Y axis on both ends and there is no change in the software...
