I've had this happen before. It looks like switching power supplies worked for OP, but if anyone else has this issue, try this:#define Z_PROBE_START_SCRIPT "M340 P0 S2290\nG4 P2000\nM340 P0 S0&qu

#define MAX_FEEDRATE_X 80

I know how to move the PS-ON (just by modification of the line #define PS_ON_PIN ORIG_PS_ON_PIN to something like #define PS_ON_PIN 16.

#define Z_PROBE_Z_OFFSET 0

#define X_STEP_PIN         54

Yes, but also  #define EXT0_PID_INTEGRAL_DRIVE_MAX 140

#define XAXIS_STEPS_PER_MM 66.67

#define MAX_FEEDRATE_X 500

//#define ULTRATRONICS

#define CONFIGURATION_H

#define Z_PROBE_X_OFFSET 0

I'm using the latest configurator (0.92.9) and I've got a Viki 2 hooked up to my Azteeg X3 Pro and it doesn't seem to be powering on or doing anything. The config.h has the #define FEATURE_CONTROLLER

#define FEATURE_SERVO 1

#define BAUDRATE 115200

#define USER_KEY1_PIN     60      // set to pin you used for switch

#define CONFIGURATION_H

#define ENDSTOP_PULLUP_X_MIN false
