Great I think I understand now. So If I wanted to use an extruder fan, I would wire both the fan and laser power to the D9 output? Typically I just use a few fans connected directly to the power supply, but good to know that’s possible if need be.

Though for dual extruders I believe I would have to set the motherboard to BOARD_RAMPS_13_EEF and use D8 for the laser/extruder fan.
