I tried change some parameter such as "DELTA FLOOR SAFETY MARGIN", "#define MIN_HARDWARE_ENDSTOP_Z  (false)". and I have no idea about resolve this problem. 

#define Z_PROBE_X1 20

#define STEPPER_HIGH_DELAY 2

in sprinter i uncomment #define RAMPS_V_1_3 in pin.h under mega so i tryed the same in repetier.

clue around line 1300 i extruder.cpp with the #define NUM_TEMPERATURE_LOOPS .... but feel most uncertain on the consequences of adding 1 to it, and where code would transfer osAnalogInputValues[my in

I use a Ultimaker v1.5.7 Motherboard. I have configured it in the online configurator and made no further changes by hand. My entry in the configuration.h is #define MOTHERBOARD 37

#define DEBUG_QUEUE_MOVE

* #define STEPPER_HIGH_DELAY 0

#define KNOWN_BOARD 1

#define DELTASEGMENTS_PER_PRINTLINE 24

Maybe a speed problem. You have DOUBLE_STEP_DELAY 1000 so with double stepping your max. frequency is 1000. So you have to hope that you never reach that,#define STEPPER_HIGH_DELAY 20 is also long but
