G33 failing consistently

[AmEv7Fam]

I was able to attach my PandaPi to my Openbeam Kossel Pro, and all that's left is configuration. However, whenever I run G33, it consistently errors out with either "homing failed" (if I don't home first) or "Z probe failed".

/**
 * Clean Nozzle Feature -- EXPERIMENTAL
 *
 * Adds the G12 command to perform a nozzle cleaning process.
 *
 * Parameters:
 *   P  Pattern
 *   S  Strokes / Repetitions
 *   T  Triangles (P1 only)
 *
 * Patterns:
 *   P0  Straight line (default). This process requires a sponge type material
 *       at a fixed bed location. "S" specifies strokes (i.e. back-forth motions)
 *       between the start / end points.
 *
 *   P1  Zig-zag pattern between (X0, Y0) and (X1, Y1), "T" specifies the
 *       number of zig-zag triangles to do. "S" defines the number of strokes.
 *       Zig-zags are done in whichever is the narrower dimension.
 *       For example, "G12 P1 S1 T3" will execute:
 *
 *          --
 *         |  (X0, Y1) |     /\        /\        /\     | (X1, Y1)
 *         |           |    /  \      /  \      /  \    |
 *       A |           |   /    \    /    \    /    \   |
 *         |           |  /      \  /      \  /      \  |
 *         |  (X0, Y0) | /        \/        \/        \ | (X1, Y0)

 *                           T1        T2        T3
 *
 *   P2  Circular pattern with middle at NOZZLE_CLEAN_CIRCLE_MIDDLE.
 *       "R" specifies the radius. "S" specifies the stroke count.
 *       Before starting, the nozzle moves to NOZZLE_CLEAN_START_POINT.
 *
 *   Caveats: The ending Z should be the same as starting Z.
 * Attention: EXPERIMENTAL. G-code arguments may change.

// Increase the FAN PWM frequency. Removes the PWM noise but increases heating in the FET/Arduino
//#define FAST_PWM_FAN

// Use software PWM to drive the fan, as for the heaters. This uses a very low frequency
// which is not as annoying as with the hardware PWM. On the other hand, if this frequency
// is too low, you should also increment SOFT_PWM_SCALE.
//#define FAN_SOFT_PWM

// Incrementing this by 1 will double the software PWM frequency,
// affecting heaters, and the fan if FAN_SOFT_PWM is enabled.
// However, control resolution will be halved for each increment;
// at zero value, there are 128 effective control positions.

// duty cycle is attained.

 * RGB LED / LED Strip Control
 *
 * Enable support for an RGB LED connected to 5V digital pins, or
 * an RGB Strip connected to MOSFETs controlled by digital pins.
 *
 * Adds the M150 command to set the LED (or LED strip) color.
 * If pins are PWM capable (e.g., 4, 5, 6, 11) then a range of
 * luminance values can be set from 0 to 255.
 * For NeoPixel LED an overall brightness parameter is also available.
 *
 * *** CAUTION ***
 *  LED Strips require a MOSFET Chip between PWM lines and LEDs,
 *  as the Arduino cannot handle the current the LEDs will require.
 *  Failure to follow this precaution can destroy your Arduino!
 *  NOTE: A separate 5V power supply is required! The NeoPixel LED needs
 *  more current than the Arduino 5V linear regulator can produce.
