What are Ramps pins on my arduino mega pins

mitch25

Hi,

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 is 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.

Thank you so much for your time, Mitch.

All the info you need is here. first result in google for "Ramps pins"

All pins have a digital pin number and some have additional analog pin numbers depending on how you use them Google arduino mega pinmap for detailed information.
