&lt;P&gt;&lt;SPAN&gt;Thanks for raising your concern via Forum.&lt;/SPAN&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;SPAN&gt;Have you tried Direct Coordinate system? In this method&amp;nbsp;rotary axis approaches the programmed position directly on the shortest path.&lt;/SPAN&gt;&lt;/P&gt;

      <description>&lt;P&gt;Hi All, I'm looking for advice again!&lt;/P&gt;&lt;P&gt;I'm running a simulteaneous 4 axis pocket job using the C axis on a SMEC lathe with Siemens 828. The part runs perfectly on the simulation. The code is running fine until the value for 'C' changes from 1.154 degrees to 359.987 degrees. The machine will go the longway round instead of the shortest route. At this point the cutter is still engaged in the part!!&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Is there any way that angles can be outputted incrementally or does anyone know if there is a parameter in Siemens to make sure the spindle goes the shortest route?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;N1135 Z-93.665 C=2.746&lt;BR /&gt;N1136 Z-94.701 C=1.154&lt;BR /&gt;N1137 Z-95.804 C=359.987&lt;BR /&gt;N1138 Z-96.922 C=359.091&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot 2019-06-17 07.35.05.png" style="width: 999px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/647829i04DC6823257C0193/image-size/large?v=v2&amp;amp;px=999" role="button" title="Screenshot 2019-06-17 07.35.05.png" alt="Screenshot 2019-06-17 07.35.05.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Any help is greatly appreciated!&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Chris&lt;/P&gt;</description>
