Added Coordinate System and G-Code Dialect / Post Processor Articles to CNCCookbook’s Online G-Code Learning Course
As promised, we’re adding additional articles to our Online G-Code Course and Tutorial at a rapid clip. I just added a new article on G-Code Coordinate Systems and another on G-Code Dialects and Post Processors. These articles will answer questions like:
- What is a Post Processor or “Post”?
- What are some of the differences in G-Code dialects and what are the most common dialects?
- What’s the difference in right-handed versus left-handed coordinate systems and should you care?
- Why are all the arcs plotting wrong in my controller or GWE’s G-Code Simulator and how do I fix it?

Engrave file with bad Post settings for Arcs: one of the most common G-Code Dialect differences between controllers…
Each installment in the G-Code Tutorial includes a description of how those concepts in G-Code work together with exercises to help you become proficient with the concepts introduced. Where relevant, we show you how to use the G-Wizard GWE Editor and G-Code Simulator to experiment with the concepts. Each installment is bite sized and shouldn’t take more than a half hour to an hour to go through including the exercises.
Our next installment will be around how manual machinsts can quickly pick up G-Code and take advantage of the MDI capability of their CNC machine.
