How to stop execution of a buffer data?

[jihuang]

During the execution of a buffer, if I issue a flex_stop_motion to the control card, the motion stops, but if I issue another flex_start, the motion control card would execute the un-finished path of the
buffer first, then execute the new motion command.
Is there any way that we could thoroughly clear the motion command for buffer following?

The clear buffer function achieves precisely this. You should also use the set operation mode function and set the axis operation to absolute position mode so that your axi will have no more references to the contour.
