#define ORIG_SDCARDDETECT -1 // Ramps does not use this port

#define AXIS_STEPS_PER_MM ((float)(MICRO_STEPS * STEPS_PER_ROTATION) / PULLEY_CIRCUMFERENCE)

OK solved it - using the online configurator, set the Fan Pin to Digital pin 4. If you want to do it manually, then add the following #define to your Configuration.h:

#define FEATURE_CONTROLLER 1

#define HOMING_ORDER HOME_ORDER_XYZ

#define BEEPER_PIN             18

#Done loading the points from the log file....

#define SDPOWER            -1 // -1 default setting

#define BEEPER_PIN             18

Changed #define SDSUPPORT 0 to 1, so how does that relate to pins.h as shown below?

#define KNOWN_BOARD 1

#define SDSUPPORT 0should be

Did swapping to EXT1 work for anyone?#define E0_PINS ORIG_E1_STEP_PIN,ORIG_E1_DIR_PIN,ORIG_E1_ENABLE_PIN,***********************************************************************************************

#define E0_PINS ORIG_E1_STEP_PIN,ORIG_E1_DIR_PIN,ORIG_E1_ENABLE_PIN,

#define EXT0_WAIT_RETRACT_UNITS 3870, in the Repetioer configurator it's 3mm.

I have a strange problem: When I start a print, the printer goes through the steps of the start script (basically Homing, Autolevel, go to side and wait until everything is heated), but while it waits

#define SDSUPPORT 0

#define X_ENABLE_ON 0

#define X_HOME_DIR -1

#define HEATER_0_PIN 9 // EXTRUDER 1
