How to update the Marlin 3D printer firmware (Ender, etc.)
- Marlin is compiled per printer — you cannot flash a generic build.
- Start from the configuration files for your exact printer and board in the Configurations repository.
- Build with PlatformIO in VS Code, then flash over USB or by SD card depending on the board.
- Keep your current firmware image; a bad Marlin build can leave the printer unable to home safely.
Always download firmware from the manufacturer or project itself. Firmwarely links out; it never hosts firmware.
