Yes it is! The motor pulley and motor drive shaft on your Marbel 2.0 have a 3mm keyway and multiple set screw locations to ensure perfect alignment every time. Should your motor pulley ever need to be serviced, it is now easy to upgrade or replace.
When engineering the Marbel 2.0 we focused on designing components to be self-serviceable and even upgradeable. As a result, almost everything can be serviced by the user and even replaced in a matter of minutes. In addition, several of the Marbel 2.0 parts are even backwards compatible with the Original Marbel Board.
