stepper Motor

Other Hardware Sensors

Hi all,

I'm using labVIEW interface for arduino to drive two stepper motors. I'm using two easy drivers on a single Arduino Uno. I have two separate power supplies(12V each) for the easy drivers. I have the digital pins of arduino connected to the step and dir pins of easy drivers.

For Stepper 1, Pin 2 Step
Pin 3 DIR

For Stepper 2, Pin 4 step
Pin 5 DIR

I'm using a VI from the LIFA example (Arduino Stepper motor). However, the first stepper runs, but if I command the second stepper to run it doesn’t runs. Only first stepper keeps on running.So pls help me on resolving this issue
