#define ORIG_E1_STEP_PIN    43

it´s quite simple, in configuration.h you see a lot of #define  and values.

#define ENDSTOP_PULLUP_Z_MIN false

#define UI_HAS_KEYS 1

#define UI_DISPLAY_RS_PIN    63    // PINK.1, 88, D_RS

#define UI_HAS_KEYS 1

//#define ADVANCED_OK

    #define EXT0_HEATER_PIN HEATER_0_PIN

#define DEFAULT_MAX_FEEDRATE          { 200, 200, 2, 25 }

    #define HEATED_BED_HEAT_MANAGER 0

Try lowering #define HEATED_BED_PID_INTEGRAL_DRIVE_MIN 80 in eeprom.

#define MIN_HARDWARE_ENDSTOP_Z true

#define HAVE_HEATED_BED 1
