Hello All,
I am working on my first 1.6 Ramps, with Arduino Mega and 3 stepper motors + A4988 drivers ( 3 axes X Y Z). I will not pilot them via Marlin firmware, but only with Accelstepper library (I am not building a 3D printer). My goal is to pilot the motors, using push buttons. The problem is, I don't know where to connect the buttons ?
Since I won't be using LCD / endstops / servos, I have plenty of pins available on the Ramps, but I don't know how to adress them in my code. For exemple : Pins D16 to D32 are free, but the Arduino won't recognize "D16".
I found the "Mega2560 pinout" but I can't find out what Mega's pin is linked to Ramps D16 pin. Thank you for your help.
Rick
