Testing Stepper Motors
August 08, 2015 05:26AM
Hello. I'm trying to build a 3D printer from used printers and scanners. I have the Arduino Mega 2560, RAMPS 1.4 and the A4988 driver combo as the electronic part. I’m trying to test out the motors to see if they work but I don’t know what code to upload to the Arduino board to do that. Can anyone help me with a simple code that turns the motor in a direction a number of steps, and then in the other direction.

Thank you for your replay. That was helpful.

Is there a diagrame with the RAMPS pin numbering (for example, on the Arduino the pin numbers are printed on the bord)?

The pin numbers are the pin numbers on the Arduino board not the numbers on the ramps board.
There are diagrams that show pins used for output of X Y Z and extruders.
Pin numbers for drivers would not normally be changed from standard so code should work as given.

Ok, but on my Arduino bord (i've added a picture o it) the biggest number is 53 and in the code, for example 
#define Z_ENABLE_PIN       62
is this code for anater type of bord?

pins 54 to 69 are Arduino pins A0 to 69
