Gary, If you can add another parallel port card ($10 on fleabay) you can have lots of extra inputs easy.
There are two speeds that are settable for homing the search speed which you set as fast as your comfortable with and the final position speed that you set slower so you can get good repetable position. Unfortunaly the last speed is done at a rapid so if you have a weak heart and a very fast machine >400IPM it will jerk real bad and scare you... In slower machines it works well. Too bad none of the developers have real fast machines or we might get another option there... Basicly it moves the axis until it sees the switch change states then backs off then comes back again to touch off then rapids to your home position. If you have limit switches you can configure them to home as well.
