Auto Bed Leveling - Error: Probing Failed - Marlin 2.0.5.1 (no replies)

Hi All,

I tried to set up the Auto Bed Leveling at a homemade Graber I3 using Marlin 2.0.5.1. When I start ABL the probe is deployed, touches the table once and then is stow, causing the error: Error: Probing Failed

I expected the probe touches 3 times each point (9 points)

In the debug Log there is a "SLOW Probe fail!" but I don't know exactly what is meant. Could you help me to understanding this error?

My Configuration about the probe and Bed Leveling:

#define Z_MIN_PROBE_PIN 19

#define Z_PROBE_SERVO_NR 0 
#define Z_SERVO_ANGLES { 100, 0 }

#define NOZZLE_TO_PROBE_OFFSET { -2, -26, 32.50 }

#define MIN_PROBE_EDGE 10

#define XY_PROBE_SPEED 8000
#define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z
#define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2)

#define MULTIPLE_PROBING 3

#define Z_CLEARANCE_DEPLOY_PROBE   37
#define Z_CLEARANCE_BETWEEN_PROBES  3
#define Z_CLEARANCE_MULTI_PROBE     3
//#define Z_AFTER_PROBING           5

#define Z_PROBE_LOW_POINT          -3

#define Z_PROBE_OFFSET_RANGE_MIN -20
#define Z_PROBE_OFFSET_RANGE_MAX 20

#define PROBING_HEATERS_OFF
#define PROBING_FANS_OFF
