Defining the direction of rotation
In order that the direction of rotation is correctly displayed in the ShopMill user interface, and
when programming ShopMill functions, the correct direction of rotation is executed, you must
make some settings that are coordinated with one another. You must align these settings to
the actual direction of rotation of the axis at the machine.
