// As of 3-28-2015, there are NO Z Probe pins defined in any board config files.
// Z_PROBE_PIN is for the signal pin only. RAMPS 1.3/1.4 boards may be able to use the 5V, Ground and the D32 pin in the Aux 4 section of the RAMPS board for the signal.
// The D32 pin in Aux 4 on RAMPS maps to the Arduino D32 pin. The Z_PROBE_PIN is setting the pin to use on the Arduino. Since the D32 pin on the RAMPS maps to D32 on Arduino, this works.
// If you have RAMPS 1.3/1.4 and want to use the RAMPS D32 pin, set Z_PROBE_PIN to 32 and use ground and 5v next to it as needed. Check the RAMPS 1.3/1.4 pinout diagram for details.
// D32 is currently selected in the RAMPS 1.3/1.4 pin file. Update the pins.h file for your control board to make use of this. Not doing so nullifies Z_PROBE_AND_ENDSTOP
// WARNING: Setting the wrong pin may have unexpected and disastrous outcomes. Use with caution and do your homework.
#define Z_PROBE_PIN -1
// Mechanical endstop with COM to ground and NC to Signal uses "false" here (most common setup).
const bool Z_PROBE_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
