Trotec circles: solid black dots at the corners. Choose three or four. Three is usual, because the empty corner tells the camera which way round the piece is. Red + blue crosshairs: red at the top right, blue at the bottom left. Mark size runs 2 to 20 mm, and "Clear of the cut" sets the gap from the piece (0 to 20 mm). The file grows to hold the marks and the panel shows the new size.
