Help with air assist

Machine: k40

Board: Cohesion3D mini

Firmware: Smoothie

I’m pretty sure I burned out the mosfet that controls the air assist. I’ve connected a multimeter to the output pins and am not getting any voltage when the air assist should be activated. I think this happened because I connected it wrong in the past and it burned out.

Is there any way to get it working off of a different pin?

Sorry to hear that.
