This action uses the platformio cli to build a Marlin firmware binary.
Make sure that in your platformio.ini you set the default_envs variable to match your printer. Example for an Ender3 v2:
...
[platformio]
src_dir = Marlin
boards_dir = buildroot/share/PlatformIO/boards
default_envs = STM32F103RET6_creality
include_dir = Marlin
...location of the resulting binary file
