2-pin fan connected to 2-pin header on Octopus Pro 446 - input voltage pwm

upload your ratos.cfg and printer.cfg please

why are you (in your printer.cfg) doing

 # Hotend cooling fan
 [heater_fan toolhead_cooling_fan]
 heater: extruder
 # 2-pin fan connected to 2-pin header on Octopus Pro 446 - input voltage pwm
 pin: toolboard_t0:PA1

when this is already defined in your ratos.cfg

 # Hotend cooling fan
 [heater_fan toolhead_cooling_fan]
 heater: extruder
 # 2-pin fan connected to 2-pin header on T0 (EBB42 v1.2) - input voltage pwm
 pin: toolboard_t0:PA1

do i need to take it out in my config

polar jacinth
#

you should, it isn't doing anything and will just make it more confusing

#

but if you hotend fan isn't coming on I would look at the wiring and such, the config looks ok to me

if i use the slicer bar in mainsail it works

if i look to ebb-42 wiring it is on PA2. if i look in RatOS.cfg it is fan_toolhead_cooling_pin=PA1,

i have found it, in started the Wizard i change the setting for the fans. thanks
