Exhaust Fan

[utrumo]

Hello. Please tell me how to test the exhaust fan and how to configure it?
Which port of the octopus board to connect it to is described in the instructions.
But it is not spelled out in the printer.cfg config, and there is nothing in the article initial startup checks about checking it.

I found pin name of this fan PD13 on this scheme

For orca slicer, according to the instructions, I corrected my printer.cfg:

Commented on these lines:

[fan]                                    # Parts Cooling Fan 
pin: EBBCan:gpio13               # Fan pin 
cycle_time: 0.00003                  # Cycle time
hardware_pwm: false              # hardware pwm

And below I added these:

#--------------------------------------------------------------------

# instead of using [fan], we define the default part cooling fan with [fan_generic] here
# this is the default part cooling fan
[fan_generic fan0]                   # Parts Cooling Fan 
pin: EBBCan:gpio13                   # Fan pin 
cycle_time: 0.00003                  # Cycle time
hardware_pwm: false

#--------------------------------------------------------------------

# this is the exhaust fan
[fan_generic fan3]
pin: PD13
cycle_time: 0.00003
hardware_pwm: false

gcode:
    {% set fan = 'fan' + (params.P|int if params.P is defined else 0)|string %}
    {% set speed = (params.S|float / 255 if params.S is defined else 1.0) %}
    SET_FAN_SPEED FAN={fan} SPEED={speed}
