Mixing Extruder with 3 seperate heaters

  YOu need to find the places in extruder.cpp where temperatures get set and controlled and remove the mixing extruder condition there. Especially setTemperature, manageTemperatures and report tempertures should be checked here. I think these are the 3 places you need to test.

  I changed nearly all the conditions for mixing extruder but it still does not work. But I dont know how to change this part:

  #if NUM_EXTRUDER > 2
      ,{
          2,EXT2_X_OFFSET,EXT2_Y_OFFSET,EXT2_Z_OFFSET,EXT2_STEPS_PER_MM,EXT2_ENABLE_PIN,EXT2_ENABLE_ON,
          EXT2_MAX_FEEDRATE,EXT2_MAX_ACCELERATION,EXT2_MAX_START_FEEDRATE,0,EXT2_WATCHPERIOD
          ,EXT2_WAIT_RETRACT_TEMP,EXT2_WAIT_RETRACT_UNITS
  #if USE_ADVANCE
  #if ENABLE_QUADRATIC_ADVANCE
          ,EXT2_ADVANCE_K
  #endif
          ,EXT2_ADVANCE_L,EXT2_ADVANCE_BACKLASH_STEPS
  #endif
  #if MIXING_EXTRUDER > 0
          ,10,10,{10,10,10,10,10,10,10,10,10,10,10,10,10,10,10,10}
  #endif
          ,{
              2,EXT2_TEMPSENSOR_TYPE,EXT2_SENSOR_INDEX,EXT2_HEAT_MANAGER,0,0,0,0
  #if TEMP_PID
              ,0,EXT2_PID_INTEGRAL_DRIVE_MAX,EXT2_PID_INTEGRAL_DRIVE_MIN,EXT2_PID_PGAIN_OR_DEAD_TIME,EXT2_PID_I,EXT2_PID_D,EXT2_PID_MAX,0,0,0,{0,0,0,0}
  #endif
              ,0,0,0,EXT2_DECOUPLE_TEST_PERIOD
          }
          ,ext2_select_cmd,ext2_deselect_cmd,EXT2_EXTRUDER_COOLER_SPEED,0,0,0
  #if EXTRUDER_JAM_CONTROL
          ,0,0,10,0,0
  #endif
      }
  #endif
  

  everytime I change this part I get a compilation error saying: braces around scalar initializer for type 'int'
  How do I need to change this code? I think this is the important part to change?

  There is absolutely no reason to change that part. All relevant parameters can get set in configuration.h. Changing this part is so critical that no one should try it. It all depends on order of variables in base classes and one comma wrong and nothing works.Look only for code like this:
  
  

  #if MIXING_EXTRUDER

          if(controller > 0 && controller < NUM_EXTRUDER) continue; // Mixing extruder only test for ext 0

  #endif // MIXING_EXTRUDER

  
  where you see that when MIXING_EXTRUDER is defined code parts get omitted for extruder > 0 which is just what you do not want in your case.
