Activate travel to fixed stop: FXS[<axis>] = 1
The movement to the destination point can be described as a path or positioning axis
movement. With positioning axes, the function can be performed across block boundaries.
Travel to fixed stop can be performed simultaneously for several axes and parallel to the
movement of other axes. The fixed stop must be located between the start and end
positions.
