配置Marlin

Marlin is a huge C++ program composed of many files, but here we’ll only be talking about the two files that contain all of Marlin’s compile-time configuration options:

  • Configuration.h contains the core settings for the hardware, language and controller selection, and settings for the most common features and components.
  • Configuration_adv.h serves up more detailed customization options, add-ons, experimental features, and other esoterica.

These two files contain all of Marlin’s build-time configuration options. Simply edit or replace these files before building and uploading Marlin to the board. A variety of pre-built configurations are included in the config/examples folder to get you started.

To use configurations from an earlier version of Marlin, try dropping them into the newer Marlin and building. As part of the build process, the SanityCheck.h will print helpful error messages explaining what needs to be changed.

Also a tool like Winmerge is usefull to compare the old file to the new one and you can copy over the settings.
