How to change default pin location for 4 wire stepper

[larz250sx]

Hello,
I made a mistake with wiring and soldering my motor driver to pins 8,9,10,11.... I was looking at an old electrical drawing... the accelstepper default pin locations are 2,3,4,5... is there any way to advoid redoing the soldering on the shield and just changing the default pin set up in the code?

Hi, 

Use AccelStepper stepper(8,9,10,11); instead of the default constructor.

Actually, the constructor call is 

AccelStepper stepper(AccelStepper::FULL4WIRE, 8, 9, 10, 11);

I will give that a shot, thank you!

Hello,

I tried that constructor call and I am getting an error saying 

"State_Machine:5: error: 'FULL4WIRE' is not a member of 'AccelStepper'

 AccelStepper stepper (AccelStepper::FULL4WIRE, 8, 9, 10, 11); // Defaults to 4 pins on 2, 3, 4, 5

                       ^

exit status 1

'FULL4WIRE' is not a member of 'AccelStepper'

I tried putting this in

AccelStepper::AccelStepper	(	uint8_t	interface = AccelStepper::FULL4WIRE,
		uint8_t	pin1 = 8,
		uint8_t	pin2 = 9,
		uint8_t	pin3 = 10,
		uint8_t	pin4 = 11,
		bool	enable = true
	)

Still no luck, same error " FULL4WIRE not a member of AccelStepper"

hi, 

this works for me (used it today to debug my stepper motor wiring)

#include <AccelStepper.h>

// Define a stepper and the pins it will use

AccelStepper stepper(AccelStepper::FULL4WIRE, 8, 9, 10, 11);

void setup()

{  

  stepper.setMaxSpeed(100);

  stepper.setAcceleration(100);

  stepper.moveTo(200);

}

void loop()

{

  if (stepper.distanceToGo() == 0)

  {

    stepper.moveTo(-stepper.currentPosition());

  }

  stepper.run();

}

what version of the library are you using? check the header of the AccelStepper.h file, the last entry of the changelog is the version number. mine is 1.57 - the latest version available through the Arduino IDE's library manager.

How do i find out which version i am using? I just copied your code and it came up error FULL4WIRE is not a member of accelstepper

Version 1.2

Thanks for your help

I updated to 1.57 and tried the constructor call change

Compiles!!! 
Thanks again and Have a great day!
