CNC and Linear Motion Related Tutorials

Here, you will find the tutorials to help you get through the process of building your CNC Machine, or related system.

Most of the tutorials on this site are created in response to the difficulties I see users having with machines mechanics, structural dimensions and the electronics that drive their CNC machines. Overwhelmingly, I have noticed that the electronics pose the most difficulty with new users. I have put together another set of wiring instructions that demonstrate a methodology that begins with a simple and straightforward wiring of only one driver and motor and follows with the remaining drivers while testing throughout. The steps per inch for many forms of mechanical option are also explained in depth. Read on and view the videos...

Primer on Homing and the Use of Limit Switches

I know, you are finished with the machine, and now, you need to set up the limit switches and be able to home the machine. Argh, the concept of restricting the machine and making it know where it is standing seems like a serious challenge. Well, not really. I am going to demonstrate a few techniques on connecting switches and how to home the machine, but in a rather unique way. You will learn how to connect limit switches and home switches using two different circuit types, normally open (NO) and normally closed (NC). I will also demonstrate a method of homing that uses the end mill (bit) to find the home position. Read more and see the videos...

Calibrating Your Axes

Do you know where your end mill is going? What, you don't have a dial indicator? No problem, calibrate your axis with my poor man's method. With just a little jogging and a bit of easy math, you will be able to calibrate your axes.
