  • If you cannot see the Marker points of the L-shaped rod clearly, you can use the middle button of the mouse to zoom in or out of the image in the reference video to click on the Marker points.
  • When clicking on the Marker points, try not to click in the wrong position or in a crooked manner. Click on the exact center of the Marker points in the image.
