+## MOD: Different Mainboard 
 It's possible to replace the stock mainboard with a different type of board, like e.g. a board from BigTreeTech (BTT). You just have to pay attention that it uses and provides 24V DC as well, as the PSU and the components like the fans etc. are running on 24V. Depending on the type of the board, you might have to use a different ABL sensor (and most likely a different type of control unit as well though, but I assume you'll run Klipper on it then anyway).
