user-1: I've been working on a 3D printer and I've come to the last step, which is wiring it all up.
The 3D printer I'm making works ONLY with the Arduino Mega. No Ramps. If I need to get Ramps later, I will, but for now, can someone please help me understand which of the Ramps pin goes with which Arduino pin. For example, in the Repetier firmware, the code is like this:
#define X_STEP_PIN         54
#define X_DIR_PIN          55
#define X_ENABLE_PIN       38
#define X_MIN_PIN           3
#define X_MAX_PIN           2

But Arduino doesn't have a 54 and a 55 pin. I've been googling this and I found that Ramps pins 54 - 69  are the same as pins A0 - A15 on the Arduino Mega.
I know this but not for the other pins...
Can someone please tell me the connection of all the Ramps pins to the Arduino pins?
Like: pin 54 on Ramps = A0 on Arduino. I need this for all of the pins.

user10394: You are right, your have all the information in your question.
Pin 54 Refers to the Arduino PIN Number, nothing to do with RAMPS.
0-53 are the digital pins and the 54 is A0, etc.
So the pin numbers should go higher than 69, which is A15.
