G-Code Basics
G-code, a programming language, instructs computer-controlled machines like 3D printers to perform specific actions.
You’ll find that G-code is based on the NIST RS274NGC standard, making it compatible with CNC milling and other applications.
As you work with G-code, keep in mind that RepRap firmwares use a variant specific to 3D printing.
- G-code standard: G-code is based on the NIST RS274NGC standard, allowing compatibility with CNC milling and other applications.
- G-code command: A G-code command is a single instruction that tells the machine to perform a specific action, such as moving to a certain location or extruding material.
- Generation options: You can generate G-code using slicing software, libraries, or write it manually, depending on your specific needs and preferences.
G-Code Structure
When generating G-code, understanding its structure is essential for effective communication with your 3D printer.
A G-code file consists of a series of commands, each starting with a letter and followed by parameters. The G1 command, for instance, specifies a linear movement in the Coordinate System.
You’ll typically see commands like G1 F3000, which instructs the printer to move at a feed rate of 3000 mm/min. G-code scripts can be added to the beginning and end of print files to perform specific actions.
G-Code Variations
Various industries employ G-code, a versatile programming language, to control computer-controlled machines.

G-Code Structure and Fields
Delving into the structure of an M103 CNC code, you’ll find that a G-code file is fundamentally a list of fields separated by white spaces or line breaks. Each field consists of a letter followed by a number, or a standalone letter (flag). The letter indicates the meaning of the field, while numbers can be integers or fractionals.
| Field Component | Description |
|---|---|
| Letter | Indicates the meaning of the field |
| Number | Can be integers or fractionals |
| Flag | A standalone letter |
| Colon | Separates multiple numbers in a parameter |
| Line Ending | Unix Line Endings, or Windows Line Endings in some firmwares |
In a G-code file, some parameters can be followed by multiple numbers, separated by colons. Understanding the structure and fields of a G-code file is essential for working with CNC machines and the Coordinate System.
G-Code Case Sensitivity
You need to ponder G-code case sensitivity, as it affects how CNC machines and 3D printers interpret your code.
