I dont want the part cooling fan on during preheat, especially when I'm only heating the bed, it is just unnecessarily loud and serves no purpose at that time.
However when I set
PREHEAT_1_FAN_SPEED to 0 it has no effect, the fan still spins at full speed as soon as I preheat either the hotend or the bed.
So why is this setting not working and how do I fix this?
I am using the latest version of Marlin.
The only one that is defined is the one that I am editing and it is the one that appears on line ~1260 of the stock configuration.h
#define PREHEAT_1_FAN_SPEED 0 // Value from 0 to 255
And this is the grep result of searching the entire firmware folder:
