I am putting together my Prusa i3 and when I change #define FEATURE_CONTROLLER 0 to something other than zero, it will not compile. I have Arduino 1.6.7 and I believe I have Protocol Version 1.0. I am

#define X_STEP_PIN         17        13

I've found the problem - it's #define ZHOME_HEAT_HEIGHT 20. My probe is much lower

#define Z_PROBE_Z_OFFSET 0

When I set  : #define EXT0_TEMPSENSOR_TYPE 102 (the MAX31855)

for 18 and nothing found. I tryed to use:#define Z_PROBE_PIN 18

First you seem to like to measure from top. That is quite risky depending on target position. In any case you should set #define ENDSTOP_Z_BACK_ON_HOME 20

#define NUM_EXTRUDER 1

#define Z_PROBE_Z_OFFSET 0

Note: I also tested setting up #define Z_PROBE_Y_OFFSET 25 (positive) but the printer behaves exactly the same.

#define Z_PROBE_X_OFFSET -37.3

#define Z_PROBE_Z_OFFSET 0

I have no real programming experience, and am wading into this project with only the #DEFINEs figured out.  The firmware config tool (ver. 0.91) is having issues with compiling (I think I picked the w

when i checked the setting "#define ALWAYS_CHECK_ENDSTOPS 0",  It seems that this was already set to zero....

Disable  #define ALWAYS_CHECK_ENDSTOPS 0

Wow thanks for the fast response and if it would be that easy that would be awesome.  I added #define START_STEP_WITH_HIGH 0
