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.
NOTE: The "G-Code" name comes from the fact that most of the printing commands begin with a G.
How to open a GCODE file
You can open a GCODE file in various 3D printing programs, including Simplify3D, Blaze3D, and GCode Viewer. Since the files are plain text files, you can also open them and view their contents in any text editor.
