Building Marlin 2.0.x Firmware for Ender 3 3D Printer and Ender 3 Clones

The Marlin firmware is an open-source firmware widely used in 3D printers, known for its flexibility and extensive feature set. This tutorial will guide you through the process of building the Marlin firmware for the Creality Ender 3 using PlatformIO, a powerful open-source ecosystem for IoT development, and Visual Studio Code (VSCode), a popular code editor.


Before we begin, make sure you have the following:

Download and install Visual Studio Code.

Open VSCode, go to the Extensions view (Ctrl+Shift+X or Cmd+Shift+X on Mac), and search for “PlatformIO IDE”. Install it.

Open a terminal or command prompt and navigate to the directory where you want to store the Marlin firmware. Run the command:

git clone
