Autolevel servo problem; probe wont retract/ extend on g28/g29

Hello. I spent hours trying to solve my problem but google isnt much help.

I got everything up. Enabled auto level and set the retract and extend angles. I used my z endstop to wire my z probe so i dont have a z endstop anymore. M280 responds fine but m401and m402 only raises the z. My z probe wont even retract or extend on g28 i have to control in manually using m280. Any ideas? If i extend my probe before g28. It wont retract for z homing. I'll attach my config.

I think you need G29, not G28.

Full firmware instructions are here (down the page a bit):

[www.thingiverse.com]

Your servo settings are off

#define NUM_SERVOS 3
That should be 1

#define X_ENDSTOP_SERVO_NR 1
#define Y_ENDSTOP_SERVO_NR 2
#define Z_ENDSTOP_SERVO_NR 1
These should be like this

//#define X_ENDSTOP_SERVO_NR 1
//#define Y_ENDSTOP_SERVO_NR 2
#define Z_ENDSTOP_SERVO_NR 0

Index starts at 0, so if you only have 1 servo, it's 0 for your Z

Also you might wanna enable safe homing, and choose coordinates that put the probe on the bed when it's deployed. That is unless your probe will always deploy on the bed

//#define Z_SAFE_HOMING

#if ENABLED(Z_SAFE_HOMING)
#define Z_SAFE_HOMING_X_POINT 20 // X point for Z homing when homing all axis (G28).
#define Z_SAFE_HOMING_Y_POINT 20 // Y point for Z homing when homing all axis (G28).
#endif

Also in Configuration_adv.h people miss this one, comment this line out
#define ENDSTOPS_ONLY_FOR_HOMING // If defined the endstops will only be used for homing
