32bit board with LPC1768, support marlin2.0 and smoothieware, support lcd2004/12864, On-board TMC2130 SPI interface and TMC2208 UART interface no additional wiring is required
I have this setup for my printer which is a extruder at e0, layer cooling fan at e1 and layer cooling fan at pin 2.3
So I changed the pin addresses in the pins_BTT_SKR_common.h file
After changing and trouble shooting my printer, the layer fan would work, but the cooling fan at the extruder wouldn't work as it should run when raise the exturder temps up to 50C, it should start running.
Checked the leds next to the mofset(which tells if there is power running) the mofset that is connected to pin 2.3 doesn't light up. but, I don't think that the mofset is the problem since it's a new board and this is my first time connecting a fan in that pin.
Tried running the fan sending g-codes wouldn't change a thing (layer fans work, but extruder cooling fan wouldn't)
After some googling, there were some people who writes the pin number on the config file so tried it. Still, no running fan.
is there anything that I am missing?
in case here's the config and pin file
Configuration_adv.h
`/**
Extruder cooling fans
Extruder auto fans automatically turn on when their extruders'
temperatures go above EXTRUDER_AUTO_FAN_TEMPERATURE.
Your board's pins file specifies the recommended pins. Override those here
or set to -1 to disable completely.
Multiple extruders can be assigned to the same pin in which case
the fan will turn on when any selected extruder is above the threshold.

btw: I know that my marlin file is a bit weird. Usually the fan pins should be in the .h file that is something called (dunno the file name exactly) pins_BIGTREETECH_SKR_V1_3 but the marlin 2.0 that I have doesn't have the exact name as that and is just called pins_BTT_SKR_V1_3.h and that doesn't contain anything related with fan pins. due to that I work on the pins_BTT_SKR_common.h file which I know, is a bit weird. I dunno which version this marlin is because when I downloaded this file it's named Marlin-2.0.x (know that it is quite a old version for sure)
Anyway, thanks for reading this looong post and many thanks for anybody that helps me. I'm really stuck
