1. A control system for controlling movement of a work tool of a machine near a desired end of travel position of the work tool, the machine including a boom member operatively connected to a frame, a stick member operatively connected to the boom member and the work tool operatively connected to the stick member, the control system comprising:

  • a controller configured to;

    store target signals indicative of end of travel positions of the boom member, the stick member and the frame;

    receive a signal indicative of actuation of an operator input device on the machine, the operator input device actuation signal indicating a desired movement of the work tool;

    determine positions and velocities of the boom member, the stick member and the frame based at least in part upon signals received from sensors on the machine;

    generate command signals to control movement of the boom member, the stick member and the frame based upon the operator input device actuation signal, proximity of the boom member, the stick member and the frame to their respective end of travel positions and the velocities of the boom member, the stick member and the frame; and

    transmit the command signals to the control system to control movement of the boom member, the stick member and the frame near the desired end of travel position of the work tool.
