Should a fan come on for a second when you pass M122 to marlin?
It turns out Servo_0 / CS_Z2 is always low, Servo_1 / CS_Z is always high and both do not react to M122, as opposed to Servo_3 / CS_X which behaves as expected.
Also a fan comes on briefly when M122.I am not sure if this behaviour is new. Maybe said fan is on a C/S line now. KEK
Pointers?
