Adding of External MOSFET for both Heat Bead & Extruder
I have the MK3s. I would like to add External MOSFET for both the extruder header and the heat bed. I understand how to connect the heater ends to MOSFETs. But what I don't know the power end. The PSU has 2 24V outputs. I know that either 1, or 2 or both are involved in the board & stepper motor, I don't care about these as I will supply them the same way already. But my question is about extruder and bed heaters.
1) Is it that 1 terminal supply to both extruder & bed's heaters?
or 2) they are supplied separately?
