may be we can do it as Feature, something like #define Feature_WorkpieceCoord

#define X_MIN_POS -100 // Posisi titik X minimum

#define ENDSTOP_PULLUP_X_MIN false

#define EXT0_EXTRUDER_COOLER_PIN -1

#define FAN_PIN HEATER_2_PIN

#define EXT1_X_OFFSET -76

#define EXT0_X_OFFSET 0

You have selected #define FEATURE_CONTROLLER 11this is for the full graphic display

#define UI_DISPLAY_CHARSET 2

#define BED_MOTOR_1_X 140

#define cDEG "\002"

1) I changed #define DISTORTION_CORRECTION_R to 80 (from 100) - my radius is 90.

#define cUP "\001"

#define E0_STEP_PIN ORIG_E0_STEP_PIN

and #define EXT0_TEMPSENSOR_PIN THERMOCOUPLE_0_PIN ?

#define _SET_OUTPUT(IO) do {DIO ## IO ## _DDR |= MASK(DIO ## IO ## _PIN); } while (0)

So, I modified the firmware to use Bluetooth (#define BLUETOOTH_SERIAL 3, #define BLUETOOTH_BAUD), compiled, and uploaded the firmware to the test Arduino Mega board via USB. 

#define EXT0_STEP_PIN ORIG_E0_STEP_PIN

#define EVENT_CHECK_FAST_KEYS(action) {}

1) Leave this as is : #define REPURPOSE_FAN_TO_COOL_EXTRUSIONS 0
