Changes made for Pathfinder 5226 controllers.

Shear limit switches are used differently than most other axes' limit switches. Usually limit switches are put into a place that is slightly past the usual range of motion because it's trying to stop the axis before it damages the machine. Shear limit switches on the other hand are in the range of motion because shears don't usually have a true feedback. So a lot of the times the user will just have the shear go from its home limit to its forward limit and then back to the home limit. The problem is these limits were not set up for directional stopping. So if the shear moved past one of the limits and the input turned off the shear will stop again when the input turns on when coming back.

The fix to this was to look at the direction the shear was moving. If the shear is moving in the direction that matches the direction the switch is supposed to be then stop the shear. If not then let the shear keep moving.
