I'm working to do a full tutorial.. maybe next month it comes.. but if you are interested, you already can buy a gt2 closed loop 400mm belt, gt2 20 or 16 teeth pulley with a bore compatible with your motor choice (look for a 200w CC black motor as mine here) and then you can buy the other basic things like Arduino Leonard board, bts7960, incremental encoder.. lots of things..😁 you can wait for my tuto or look for another one
