Learn Basic G-Code
Understand CNC Machines


  • CNC Simulator

This course will teach you how to create G-Code so you can control CNC machines. This is very useful if you are a machinist or want to be a DIY and create what ever you can imagine in your own garage. You will be given material to teach you the basics and watch tutorials of G-Code applied to real parts. This course will use CNC simulators so you can see what the code you create actually does. The course will provide you with the materials necessary to turn drawings into the code required to make it a physical part.

My background is in engineering with an emphasis in physics. I have a passion for learning and teaching those that enjoy learning as much as I do. I am a jack of many trades and want to try to make the complex topics much easier to understand by focusing on the essential concepts. Many engineers might know this as the KISS Principle. So my goal is to avoid any unnecessary complexity in trying to convey essential topics to you. Learning from my mistakes and gaining the tricks that I have learned along the way will give you a great foundation and help you take that next step.
