Changement automatique de filament/couleur

This document illustrates the procedure to automate filament or color changes during 3D printing by inserting the 'M600' command into the GCode file. Users are instructed to slice their object, identify the relevant layer numbers using visualization tools, and edit the GCode file using a text editor to include 'M600' at specified layers. Multiple filament changes can be programmed by repeating the operation for different layers. The modified GCode is then saved and transferred to the 3D printer's SD card for execution.
