// 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 D1 pin in the Aux 1 section of the RAMPS board for the signal.
// The D1 pin in Aux 1 on RAMPS maps to the Arduino D1 pin. The Z_PROBE_PIN is setting the pin to use on the Arduino. Since the D1 pin on the RAMPS maps to D1 on Arduino, this works.
// If you have RAMPS 1.3/1.4 and want to use the RAMPS D1 pin, set Z_PROBE_PIN to 1 and use ground and 5v next to it as needed. Check the RAMPS 1.3/1.4 pinout diagram for details.
// WARNING: Setting the wrong pin may have unexpected and disastrous outcomes. Use with caution and do your homework.
