For computed tapping cycle to work correctly, the Spindle format in XBUILD has to be completed. The <SPINDLE> reserved word also needs to be added to the Linear format.
Example Spindle format:
{N<SEQ>}<SPINDLE><EOB>
Example Linear format:
{N<SEQ>}{<F-UNITS>}{<COMP-STAT>}{<MOTION>}
{X<X-COORD>}{Z<Z-COORD>}{F<FEED>}{<SPINDLE>}
<EOB>
