Hi all
while my 3d printer is out of service, i'm playing around with stepper motors.
when i use the test code, everything works fine, all the motors turn correctly, but when i try to modify other sketches to run on ramps ( i use the pin declaration and configuration that are present on the test code), nothing happens.
i've googled a lot, but i can't understand/find the right information that i need: can someone please tell me what is the equal pin for the hardware pins that are declared in the test code?
if i haven't explained well: in the test code (from reprapwiki), the X_STEP_PIN is the hardware pin 54, what is the software pin (the ones that are printed on the pcb) of those hardware?
sorry for my bad english and thanks for the time
