The only time it raises the Z axis is before the initial probe and it does not probe each position twice. Again this maybe a config issue, so here is what I think are the relevant config items. Also I added a serial dump to probe_pt to output z_before each time it's called.\r\n\r\n    #define X_PROBE_OFFSET_FROM_EXTRUDER -22     // Probe on: -left  +right\r\n    #define Y_PROBE_OFFSET_FROM_EXTRUDER -19     // Probe on: -front +behind\r\n    #define Z_PROBE_OFFSET_FROM_EXTRUDER -12.20  // -below (always!)\r\n\r\n    #define Z_RAISE_BEFORE_HOMING 15\r\n    #define Z_RAISE_BEFORE_PROBING 15\r\n    #define Z_RAISE_BETWEEN_PROBINGS 10\r\n    #define Z_RAISE_AFTER_PROBING 5 \r\n\r\nHere's the output of G29 V4\r\n\r\n    Marlin1.0.2\r\n    echo: Last Updated: Mar 29 2015 06:28:19 | Author: (none, default config)\r\n    Compiled: Mar 29 2015\r\n    echo: Free Memory: 4770  PlannerBufferBytes: 1232\r\n    echo:Hardcoded Default Settings Loaded\r\n    echo:Steps per unit:\r\n    echo:  M92 X80.00 Y80.00 Z4000.00 E106.00\r\n    echo:Maximum feedrates (mm/s):\r\n    echo:  M203 X300.00 Y300.00 Z2.00 E25.00\r\n    echo:Maximum Acceleration (mm/s2):\r\n    echo:  M201 X2000 Y2000 Z100 E10000\r\n    echo:Accelerations: P=printing, R=retract and T=travel\r\n    echo:  M204 P2000.00 R3000.00 T2000.00\r\n    echo:Advanced variables: S=Min feedrate (mm/s), T=Min travel feedrate (mm/s), B=minimum segment time (ms), X=maximum XY jerk (mm/s),  Z=maximum Z jerk (mm/s),  E=maximum E jerk (mm/s)\r\n    echo:  M205 S0.00 T0.00 B20000 X15.00 Z0.40 E5.00\r\n    echo:Home offset (mm):\r\n    echo:  M206 X0.00 Y0.00 Z0.00\r\n    echo:PID settings:\r\n    echo:   M301 P34.18 I3.07 D95.19\r\n    echo:Filament settings: Disabled\r\n    echo:Z-Probe Offset (mm):\r\n    echo:   M851 Z-12.20\r\n    ok\r\n    G29 Auto Bed Leveling\r\n     z_before: 15.000\r\n    Bed X: 35.000 Y: 20.000 Z: 11.883\r\n     z_before: 15.000\r\n    Bed X: 170.000 Y: 20.000 Z: 11.418\r\n     z_before: 15.000\r\n    Bed X: 35.000 Y: 170.000 Z: 10.980\r\n     z_before: 15.000\r\n    Bed X: 170.000 Y: 170.000 Z: 10.525\r\n    Eqn coefficients: a: -0.00340279 b: -0.00598749 d: 12.11915874\r\n    Mean of sampled points: 11.20156192\r\n     \r\n    Bed Height Topography: \r\n    +-----------+\r\n    |...Back....|\r\n    |Left..Right|\r\n    |...Front...|\r\n    +-----------+\r\n     -0.22181 -0.67631\r\n     +0.68119 +0.21694\r\n\r\n    planeNormal x: 0.003403 y: 0.005987 z: 1.000000\r\n     \r\n\r\n    Bed Level Correction Matrix:\r\n    +0.999994 +0.000000 -0.003403 \r\n    -0.000020 +0.999982 -0.005987 \r\n    +0.003403 +0.005987 +0.999976 \r\n    ok\r\n    echo:endstops hit:  Z:10.53\r\n\r\nI'm getting acquainted with the code, but will take some time to do so.
