Setting the Direction of Steppers.

[Imagineering]

What is the normal method of setting the Direction of Stepper rotation when setting up the Software?
I've just started using TurboCNC and can see two options - Physically changing the Phase Wiring to the Stepper or changing the HI/LOW setting for Step/Direction when setting up the Axes.
I'm using the HI/LOW settings at the moment - are there any problems associated with this method??

There should be no difference either way.
