What is a GCODE file?

A GCODE file contains commands in G-Code, which is a language used to describe how a 3D printer should print a job. It stores instructions in plain text with each line representing a different command, such as how fast the printer should print, the temperature it should be set at, and where the printing parts should move. GCODE files are created by slicing programs, such as Simplify3D and Slic3r, that translate CAD drawings into G-Code, which a 3D printer can read.

3D printing requires a large number of instructions for exact printing. This involves separating a job into many layers. Instructions are generated for each layer of the job or object and stored in a file, such as the GCODE file, which is referenced by a 3D printer.

G-Code is a standard printing language used by many 3D printers. However, some 3D printers use different file formats for storing printing commands, such as .STL, .OBJ, .X3G, .3MF, and .AMF.

GCODE files can be opened by various 3D printing programs, such as Simplify3D, GCode Viewer, are only meant to be used by 3D printers but you can open them with a text editor since they are saved in plain text.

NOTE: The "G-Code" name comes from the fact that most of the printing commands begin with a G.
