hi everybody, i own a chinese i3 knockoff, namely the Anet A8 which i'm improving in various ways, including replacing the melzi controller with a RAMPS 1.4 on which i put Marlin 1.1.0RC6. unfortunately, these chinese i3s have a 5 button panel, unlike the classic encoder ones. i managed to get the LCD working, but of course, for the buttons, there needs to be support in Marlin. some guys overby Braccoz - Firmware - Marlin
