Ryper Mod from the nice Bear Hemera and modified to work with MMU2S+1 Ryper mod.
It requires a special firmware version not published, if you like to use Hemera with MMUs you need to choose currently another design with a filament sensor using the tension control from Hemera as is the one´s can trigger the correct filament change process.
