The G09 command is used to precisely stop at a given point.

The G09 command is non-modal and acts only in the block in which it is specified, without affecting the subsequent control program blocks of the CNC machine.

When the G09 command is found in the block in which the motion commands are located, the axis motion slows down when approaching the end point of the trajectory and the position is checked in order to achieve precisely defined coordinates before proceeding to the next control program block.
