Order of Stepper Pins in Stepper Library

Other Hardware Motors, Mechanics, Power and CNC
10

I have 16 motors wired up to a Mega.
Mine are also blue-pink-red-orange-yellow coming out of the motor.
They plug onto the ULN2003 board as red-blue-pink-yellow-orange.
I did have a small batch of motors (out of 96) that rotated opposite direction from all the rest, and I depinned the ULN2003 connector end and replugged in the wires to turn the same direction as the rest, the one I am looking at might be one of them.
IN1-2-3-4 connect to 4 adjacent pins, and I have a note in my code that Stepper pin call out is important

Stepper stepper0(STEPS, 5, 3, 4, 2); //create the stepper0  <<< Order here is important
Stepper stepper1(STEPS, 6, 8, 7, 9); //create the stepper1  <<< Order here is important
Stepper stepper2(STEPS, 10, 12, 11, 13); //create the stepper2  <<< Order here is important
Stepper stepper3(STEPS, 17, 15, 16, 14); //create the stepper3  <<< Order here is important
Stepper stepper4(STEPS, 21, 19, 20, 18); //create the stepper4  <<< Order here is important
Stepper stepper5(STEPS, 22, 24, 23, 25); //create the stepper5  <<< Order here is important
Stepper stepper6(STEPS, 29, 27, 28, 26); //create the stepper5  <<< Order here is important

Stepper stepper7(STEPS, 33, 31, 32, 30); //create the stepper7  <<< Order here is important
Stepper stepper8(STEPS, 37, 35, 36, 34); //create the stepper8  <<< Order here is important
Stepper stepper9(STEPS, 41, 39, 40, 38); //create the stepper9  <<< Order here is important
Stepper stepper10(STEPS, 45, 43, 44, 42); //create the stepper10  <<< Order here is important
Stepper stepper11(STEPS, 49, 47, 48, 46); //create the stepper11  <<< Order here is important
Stepper stepper12(STEPS, 53, 51, 52, 50); //create the stepper12  <<< Order here is important
Stepper stepper13(STEPS, 57, 55, 56, 54); //create the stepper13  <<< Order here is important
Stepper stepper14(STEPS, 61, 59, 60, 58); //create the stepper14  <<< Order here is important
Stepper stepper15(STEPS, 65, 63, 64, 62); //create the stepper15  <<< Order here is important
Stepper stepper16(STEPS, 69, 67, 68, 66); //create the stepper16  <<< Order here is important

Figure out what yours is, and stick to it.
