Marlin 1.1.0 RC3 z servo doesn't move

Attempted to use Marlin 1.1.0 RC3 and the Z endstop servo no longer moves. It works fine in 1.0.2.

Arduino IDE 1.5.6r2 and 1.6.7.
RAMPS 1.4 on a Mega2560
EEPROM disabled in Marlin
Auto bed leveling enabled with four test points.

----------------------
#define NUM_SERVOS 1 // Servo index starts with 0 for M280 command

//#define X_ENDSTOP_SERVO_NR 1
//#define Y_ENDSTOP_SERVO_NR 2
#define Z_ENDSTOP_SERVO_NR 0
#define SERVO_ENDSTOP_ANGLES {{0,0}, {0,0}, {100,178}} // X,Y,Z Axis Extend and Retract angles
------------------

Put the angles in all three, no change.
Switched servo between all servo connections, nothing
Enabled all three servos with the same angles, z doesn't move.
M401 & M401 just move the Z up and M280 nothing happens.

So, is there a setting I missed somewhere to get it to work?
