after flashing my printer keeps booting. It shows progress bar and after it's full it starts again from the beginning.

Thanks for your fast response. I've done all that and tried to disconnect all the other pins but these didn't fix it :(

Is this correct?  

If I comment out #define EEPROM_SETTINGS then it boots to main menu. Button works but rotation doesn't, but anyway my board is alive. I guess this isn't the final solutions?
