what about #define HEATED_BED_PREHEAT_TEMP 55.. should I set that to zero? Thanks again.. Richard 

#define HAVE_HEATED_BED 1

You must delete also the #defines which override old value that you want to keep. As programmer it was clear for me, but I know I did not say that.

#define SDSS            10

#define SDSS 10

#define X_MIN_POS -35

#define HOMING_ORDER HOME_ORDER_XYTZ

#define Z_PROBE_X_OFFSET -32

#define ENDSTOP_X_BACK_ON_HOME 35

It's #define EXTRUDER_FAN_COOL_TEMP 50

#define EXT0_EXTRUDER_COOLER_PIN 6

#define Z_PROBE_DELAY delayInMc

#define SERVO0_PIN 5

// #define UI_DISPLAY_RS_PIN 32

#define DISTORTION_CORRECTION 1

#define ENDSTOP_Z_BACK_ON_HOME 0

#define Z_PROBE_Z_OFFSET 0
