M4 Calibration seems good, but jogging literally does nothing

I’ve got my M4 assembled, up on the frame, and run it through it’s first calibration, which it passed (so it tells me). But when I try jogging it anywhere, the fan spins up, but none of the motors do, it doesn’t move at all. However, Z axis moves do work. I’m running 0.72.1 Where do I start diagnosing what’s wrong?
