The slicer will then translate the 3D file into the appropriate G-Code for your machine. To counter this, most slicers have options to set up your printer profile so that you can choose the right flavor for your machine. However, some niche commands aren’t the same, which can lead to print errors if used with the wrong machine. Different flavors exist due to the different G-Code standards and firmware that various printer brands use.įor example, standard commands like the move, heater on, etc., are common among all printers. The G-Code flavor refers to the way your printer’s firmware (Operating System) expects its G-Code to be formatted. They are prefaced by an M, which stands for miscellaneous. Another thing M-Code is responsible for is setting the bed’s temperature and the nozzle’s temperature. Things they are responsible for include turning the motors on and off, setting the fan speed, etc. They are machine commands controlling the printer’s other functions apart from the printhead’s motion. M-Code stands for Miscellaneous commands. They are prefaced by a G to show that they are G-Code.

Using G-code, you can move the nozzle in a straight line, position it in a specific place, raise or lower it, or even move it through a curved path. Its primary function is to control the print head’s motion, position, or path.

Types of G-CodeĪlthough the general name for CNC commands is G-Code, we can broadly divide the commands into two categories They include: Popular slicers on the market include PrusaSlicer and Cura. It also controls and sets specific printer functions like turning on the heater, fans, cameras, etc. It then specifies the coordinates or path for the printhead to pass through to build up these layers. This program takes your 3D model and slices it into thin 2D layers. G-Code for 3D printers is created using a special application called a slicer.
