Where is PIN 63 ?
in Motherboard
One thing is unclear for me.
In section "Z- probing" in configuration.h, in documentation. I read that: " #define Z_PROBE_PIN 63 "
What's about ?
is it the number pin of the 2560 itsef : pin PJ0 (RXD3/PCINT9)
or the number pin of the board : Digital Pin 15 (RX3) , pin 10 on the connector EXP3 card RUMBA ?
What is really the "standard" pin to connect this Z_Probing ? Pin number for 2560 or pin on the board ?

I find that : https://www.arduino.cc/en/Hacking/PinMapping2560
There are only one Pin 63 on Arduino 2560, it is the 63th pin of 100 on the chip 2560 ! This is the: Digital Pin 15 for the firmware Repetier
Why don't say that ?
It's very simple !
It's the physical pin number 88 on the chip atmega2560, also labeled Analog Pin 9
labeled A9/D63 on the connector AUX2 on the RAMPS (pin conn 4 )
re-labeled Pin 63 in the firmware
and localised on connector AUX3 (pin conn 7) on RUMBA card
Résumé: Pin 88 => Analog Pin 9 => Digital Pin 63 => Analog pin 9
Simple !
I'm right ? It's OK ?
Thanks !
if there is a comment, it is absolutely unclear.
but whatever. thanks for the firmware even if sometimes chaotic :-)
