Hello
I have a problem with the MKS 1.3 board. It is a hotend fan. In the configuration I have set up like this:
# Switch module for fan control
switch.fan.enable true # Enable this module
switch.fan.input_on_command M106 # Command that will turn this switch on
switch.fan.input_off_command M107 # Command that will turn this switch off
switch.fan.output_pin 2.4 # Pin this module controls
switch.fan.output_type pwm # PWM output settable with S parameter in the input_on_comand
switch.fan.max_pwm 255 # Set max pwm for the pin default is 255
switch.fan.startup_state true
#switch.misc.enable true # Enable this module
#switch.misc.input_on_command M42 # Command that will turn this switch on
#switch.misc.input_off_command M43 # Command that will turn this switch off
#switch.misc.output_pin 2.4 # Pin this module controls
#switch.misc.output_type digital # Digital means this is just an on or off pin

# Temperatureswitch. See http://smoothieware.org/temperatureswitch
# Automatically toggle a switch at a specified temperature. Different ones of these may be defined to monitor different
# temperatures and switch different swithxes. Useful to turn on a fan or water pump to cool the hotend
temperatureswitch.hotend.enable true #
temperatureswitch.hotend.designator T0 # first character of the temperature control designator to use as the temperature sensor to monitor
temperatureswitch.hotend.switch misc # select which switch to use, matches the name of the defined switch
temperatureswitch.hotend.threshold_temp 40.0 # temperature to turn on (if rising) or off the switch
temperatureswitch.hotend.heatup_poll 15 # poll heatup at 15 sec intervals
temperatureswitch.hotend.cooldown_poll 60 # poll cooldown at 60 sec intervals

The fan works well according to the setting right after start. I choose the file to print. The straw heats up and then hotend and when it reaches the set temperature, the fan stops and the printer starts printing. I need to manually turn it on. What could be wrong?
