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.
