 Smoothie has up to 6 MOSFET controls ( 6 on 5X, 4 on 4X and 2 on 3X ). You have to connect your PSU to the power input connector for those FETs, and connect your power consuming element ( be it heating element, spindle, etc... ) to the power outputs of those same FETs. Essentially Smoothie connects/disconnects the element ( connected to the MOSFET connector ) from the PSU ( connected to the power input connector ) as needed to maintain temperature or as requested by G-codes. Smoothie has up to 6 MOSFET controls ( 6 on 5X, 4 on 4X and 2 on 3X ).
