[Ender3] Set fan speed in preheat presets

Marlin Firmware Service Feature Requests

Hello,

Thanks for your amazing tool! :slight_smile: I noticed cooling fan running at 100% during preheat (which is not desired). Looking at Marlin docs I noticed it is possible to set fan speed inside presets:

#define PREHEAT_1_TEMP_HOTEND 180
#define PREHEAT_1_TEMP_BED 70
#define PREHEAT_1_FAN_SPEED 0 // Value from 0 to 255

#define PREHEAT_2_TEMP_HOTEND 240
#define PREHEAT_2_TEMP_BED 110
#define PREHEAT_2_FAN_SPEED 0 // Value from 0 to 255

Please make this setting available under Filament Options → Filament Presets next to Extruder and Bed temperatures.

Current workaround: there is M145 command (Set Material Preset | Marlin Firmware) which can be used to modify presets and M500 to save them to EEPROM.

Thanks in advance,
Mike
