What is G-Code?
G-code is a collection of codes or functions that are part of numerical control or NC programming language. The Electronic Industries Alliance developed the earliest versions of this type of NC coding during the 1960’s. Serving as the standard CNC in the United States, the coding has undergone some enhancements. At present, a version adopted in February 1980 and known as RS274D is the standard in the United States and various other countries around the world. However, a different standard, known as DIN 66025, is commonly used in Europe. All types of code within the structure of NC coding focus on different functions. With G-code, the focus is on the actual positioning of the tool in order to accomplish the appropriate task. This contrasts with other types of code within the system. For example, S-code has to do with the speed of the tool, while F-code addresses the feed of the tool. While G-code may form the basis for the configuration of many different types of tools, it is not unusua
G-Code is the common name for the programming language of CNC Machines. Somewhat of a generic, catch-all type of term for CNC programming language. Very few machines adhere to this standard today. There are as many varations as there are manufacturers. This is how I think of G-Code. It is a simple language built off of the Cartesian Coordinate System for motion control. That is a mouthful. I don’t know if that is exactly right, but you will get my meaning in a second when we go through some code line by line. You will remember your High School Geometry soon enough. For the real pros out there, you know there is much more to G-Code then that, but it is a good place to start thinking about it. You will see many variations of the G-Code name like: Gcode gcode G-Code g-code G Code G-Code Are there other “Codes?” In a word…Yes. We will get to that in a moment. G-code is also the name of any command in a CNC program that begins with the letter G. G-Codes generally tell the machine to perform

Where does it come from? G-code (the RS-274 machine tool programming language) is a language for describing how to move machine tools. For example, the command “G1 X1.000 Y1.000″ would cause a milling machine to move the cutter from its current position to the location X=1.000″, Y=1.000”. G-code includes commands for spindle speed, feed rate, circular and helical movements, plus other features to make using multiple tools and other tasks efficient. Many CAD/CAM programs can produce the exact flavor of G-code that EMC uses, in which case you don’t need to write any G-code. Other times you might want the fine control that writing your own G-code gives you. EMC2 implements most standard G-code words, with some nice extensions to make writing your own code easier. How do I install EMC? EMC runs on a desktop PC running the free Linux operating system. But don’t worrythe Live CD (download from www.LinuxCNC?.org) makes installing Linux and EMC easy on many desktop computers, and you can try i
