#define TRY_AUTOREPAIR_LCD_ERRORS

you wrote#define Z_PROBE_X_OFFSET -50,49

#define Z_PROBE_Z_OFFSET 0

#define FEATURE_SAFETY_DOOR true

#define DRIVE_SYSTEM 3

#define X_HOME_DIR -1

#define ENDSTOP_PULLUP_X_MIN    true

#define RETRACTION_LENGTH 3                       

and the pin assigned to the #define ORIG_Y_MAX_PIN is a -1 which I am pretty sure is unassigned. 

#define ENDSTOP_Y_MAX_INVERTING   true

#define ENDSTOP_PULLUP_X_MIN    true

 #define EXT0_TEMPSENSOR_PIN THERMOCOUPLE_1_PIN

It would be nice to be able to set the board fan PWM via a #define. It is already being PWMed but with a hard coded value of 255 for the speed.

#define DEFAULT_AXIS_STEPS_PER_UNIT {80.00,80.00,4000.00,606.09}

#define X_HOME_DIR -1

#define EXT0_DECOUPLE_TEST_PERIOD 0

I'd say #define HEATED_BED_MAX_TEMP 110 is the reason.

#define HEATED_BED_HEAT_MANAGER 2 

#define YAXIS_STEPS_PER_MM 80

#define MIN_HARDWARE_ENDSTOP_X true
