Need help configuring extruder_fan & part_cooling_fan

Hello,

I am trying to configure marlin 1.1.8 working with my printer, but I am having problem working the extruder_fan and the part_cooling_fan.
Can anyone please help?

About the extruder_fan. I have set pin 8 in RAMBo board, which is the FAN0.

#define E0_AUTO_FAN_PIN 8

But it gives me the following:

SanityCheck.h:977: error: #error "You cannot set E0_AUTO_FAN_PIN equal to FAN_PIN."
#error "You cannot set E0_AUTO_FAN_PIN equal to FAN_PIN."

There must be a problem in the code, because in marlin 1.0.2 it was working fine.

And about the part_cooling_fan. Where do I change the pin? In which folder?

Thank you all.

And Where is your part cooling Fan connected to? it looks like you have your Partcooling fan also on Pin 8.
this is not allowed, and would make no sense, because Partcooling would be always on With the Hotend..

Hi kabelfrikkler,

I have attached a photo from rambo board.
I have my extruder's heater block connected to "heat 0".
The extruder's fan is connected to "fan 0" and this is pin 8.
The part cooling fans are connected to "fan 2" and this is pin 2, as per pins RAMBO in marlin

The problem is that when I try to upload:
#define E0_AUTO_FAN_PIN 8, it gives me the following:
SanityCheck.h:977: error: #error "You cannot set E0_AUTO_FAN_PIN equal to FAN_PIN."
#error "You cannot set E0_AUTO_FAN_PIN equal to FAN_PIN."
So it must be a bug somewhere.

For the part cooling fan, I have tried:
#define FANMUX0_PIN 2, but when I give the M106 the extruder's fan is starting. this is wrong.
