Trouble controlling stepper motor

Stepper motor driver: TB6600

stepper_motor_test.vi outputs the pulse signal into the driver via an Arduino, the driver uses this pulse signal to drive a stepper motor. The driver also requires Enable and Direction outputs from the arduino.

The problems are:

1) Wait.vi cannot be lower than 1ms. Ideally I want delay to be as low as 10 microsecond.

2) The Motor does not rotate as smoothly as compared to controlling it directly with Arduino IDE.

 

I had a look at the Arduino stepper motor example in the example folder, but I cant make it run and I have no idea how the example works.

 

Is there a better way of controling the stepper motor than my .vi?

Or can I modify the example to make it work?
