      <p class="para_topic">The Chase Passes option allows you to specify spring passes at the end of the thread to control size of thread and minimize tool deflection. The system makes the chase passes at the total thread depth. You can also specify the number of OPSTOPS to be output and a local return move.</p>
      <p class="para_topic">The series of chase passes is always bracketed by OPSKIP/ON and OPSKIP/OFF. In addition, if you specify even one OPSTOP, then the series of chase passes will also be bracketed by OPSTOPs. &nbsp;Likewise, an OPSTOP will be output for each of the latter passes where it is desired.</p>
      <div class="title_division">Number of Chases</div>
      <p class="para_division">Before the first chase pass, the system moves the tool to the Local Return Point, if active, and outputs an OPSTOP and OPSKIP/ON command. Then the desired number of chase passes are output with the final one followed by an OPSTOP and OPSKIP/OFF.</p>
      <div class="title_division">Number of Opstops</div>
      <p class="para_division">For the number of opstops you specify, the system outputs an additional OPSTOP command before each of the last chase passes. For example, if you specify four chase passes and two opstops, the additional opstops are output before the last two chase passes.</p>
      <div class="title_division">Local Return </div>
