This guide will explain the 10 most commonly used commands, what they do, and how to edit them in Simplif圓D. For any maker, it is beneficial to have a basic knowledge of G-Code to understand how your 3D printer works, debug or perform maintenance on your machine, and verify your print files. These commands tell your 3D printer exactly what actions to perform – where to move, what speed to use, what temperatures to set, and much more. Most of these commands start with a G (hence the name), but there are also some common machine-specific codes that start with an M. Did you know that 3D printers have their own language? Today, many desktop 3D printers use a numerically controlled programming language made up of a series of commands called G-Code.
