#define CONFIGURATION_H

I have just downloaded the new firmare with the ALTERNATIVE_JERK implemented. As you suggested, I included this in the configuration.h: #define ALTERNATIVE_JERK

/** \brief Delta drive type: 0 - belts and pulleys, 1 - filament drive */<br />#define DELTA_DRIVE_TYPE 0<br />#if DELTA_DRIVE_TYPE == 0<br />/** \brief Pitch in mm of drive belt. GT

#define ENDSTOP_PULLUP_X_MIN false

#define ALTERNATIVE_JERK

Another question: What do you recommend for #define STEP_DOUBLER_FREQUENCY ? Since I am using an ARM, this value could be higher than for the AVR, but do you maybe have a best-case value?

#define PRINTLINE_CACHE_SIZE 16

#define HEATED_BED_SENSOR_PIN TEMP_2_PIN

#define X_HOME_DIR 1

#define ALTERNATIVE_JERK

#define DEFAULT_MINSEGMENTTIME        20000

I see#define NUM_EXTRUDER 1 so that is correct in config.h

I have my extruder fan plugged into D9 on my Ramps 1.4 board, in the Repetier firmware #define FAN_BOARD_PIN was at -1 as well as in Pins.h as per default. The red light which indicates the fan is on

Bed slam, betcha saw that coming #define Z_PROBE_ON_HIGH false change to false and G32 s0 probes my 3 points five times and seems to work 

#define ENDSTOP_PULLUP_Z_MIN false

1. Z-min is false (I found that info in another post) [discovered software endstops as well, A+ feature i like it] 2. The Z-probe pin is set to #define Z_PROBE_PIN ORIG_Z_MIN_PIN which i would assume

<rectangle color="#dddddd" yMin="0" yMax="200" xMin="0" xMax="200"/>

#define Z_PROBE_HEIGHT 1

#define ENDSTOP_PULLUP_X_MIN true

#define THERMOCOUPLE_0_PIN  2   // Dua analog pin #59 = A5 -> AD 2
