If you have any issues related to the CR Touch please report it here, if not then report it directly to the Marlin firmware page.
To build and upload Marlin you will use one of these tools:
- The free Visual Studio Code using the Auto Build Marlin extension.
- The free Arduino IDE : See Building Marlin with Arduino
- You can also use VSCode with devcontainer : See Installing Marlin (VSCode devcontainer).
Marlin is optimized to build with the PlatformIO IDE extension for Visual Studio Code. You can still build Marlin with Arduino IDE, and we hope to improve the Arduino build experience, but at this time PlatformIO is the better choice.
Marlin is published under the GPL license because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork.
While we can't prevent the use of this code in products (3D printers, CNC, etc.) that are closed source or crippled by a patent, we would prefer that you choose another firmware or, better yet, make your own.
