Fan2 for light
I have an effector light connected to fan2 on radds When I press light on radds display it goes on for a second then goes off. When I start the printer it also goes on for a second then goes off. Why doesn't stay on?

CASE_LIGHTS_PIN whcih I do not see in your config part.
#define FEATURE_FAN2_CONTROL 1
mean enable second fan and that also uses FAN2_PIN and will disable a light enabled with M355.In that case
M106 P1 S255 should enable the light.
#define FEATURE_FAN2_CONTROL 0
should be set so it does not use same pin. Also check if you have no cooler pins set to fan 2.
