Stock Tevo Tarantula single extruder small bed

Running Jim Browns MarlinTarantula-EasyConfig-1.1.x (MarlinTarantula-EasyConfig-2.0.x freezes during compiling)

When print starts Fan 2 starts (I don't have a fan 2 and have no idea where the pins are), while Fan 1 stays at 0. Have go into Tune to manually start Fan 1.

Where do I change this?

Help!!!

You can set this in Startup/End G-Code

//Fan speed 0 - 255
M106 P0 S128 ; P0 = 1nd Fan 
M106 P1 S128 ; P1 = 2nd Fan

Thank You ... No more plugged extruder. ... At least From my memory !!! lol

That got it to run, but only at 128. Is that what the S128 means? If it is I can increase it there and make P1 S0 ??? Since I don't have a 2nd 1

Do you know where in the firmware to edit it?

Here is where extruder E1 is configured to a Fan.

Configuration.h
#define MOTHERBOARD BOARD_MKS_GEN_13

pins_MKS_GEN_13.h
#define MOSFET_D_PIN                           7

pins_RAMPS.h
#if DISABLED(HOTEND_USE_E1)
    #if EITHER(HAS_MULTI_HOTEND, HEATERS_PARALLEL)
      #if HOTENDS == 1
        #define FAN1_PIN              MOSFET_D_PIN // Enable 2nd Fan
      #else
        #define HEATER_1_PIN          MOSFET_D_PIN
      #endif
    #endif
#endif

I use the 2nd Fan for the controller cooling Fan // Unless you need extruder E1 as an extruder.
To use a 2nd Fan connect it to E1
