Modified fan_generic, Print cooling fan. [fan_extended my_fan_extended]
all parameters from original [fan] section https://www.klipper3d.org/Config_Reference.html?h=fans#fans linear regulation of fan speed, if additional parameters provided:\
[fan_extended my_fan]
#min_speed: 0.0
#the minimum speed will be set after the printer is in ready state. default = 0, from 0 to max_speed
#max_speed: 1.0
#maximum allowed speed. default 1.
#min_temp: 0
#minimal temperature, temp_sensor <= min_temp, speed = min_speed
#max_temp: 300
#maximum temperature, temp_sensor >= max_temp, speed = max_speed
#linear adjustment within min_temp...max_temp, speed proportionally between min_speed and max_speed
#temp_sensor: temperature_sensor host_sbc
#the value of the sensor that is taken for adjustment
#specified as the full name of the object.
#for example, if you need to adjust using the host temperature
#[temperature_sensor host_sbc]
#sensor_type: temperature_host
