Marlin Firmware @marlinfw.org · 28/09/2025Most people just use Auto Build Marlin in VSCode. You will need to be more comprehensive in setting up your configuration. I was merely pointing out that building Marlin is relatively trivial if you have a good configuration. 100
Marlin Firmware @marlinfw.org · 28/09/2025The options that were modified allowed the firmware to build for SKR3-EZ. The mftest command is included in the Marlin project and it builds Marlin from the command line. The -a flag tells it to automatically determine the correct target env. 200

Marlin Firmware @marlinfw.org · 14/09/2025Change nothing else —only the MOTHERBOARD— as a starting point. If it builds and works you can then make your own adjustments.
