-Shiney tube ends with ragged or burred edges with CONCAVE curves facing the laser scanner camera can create an overload problem for the exposure. This can create flyers (points that are not on the surface) in any laser camera.
+Shiney tube ends with burred edges that form CONCAVE curves facing the laser scanner camera can create an overload problem for the exposure. This can create flyers (points that are not on the surface) in any laser camera.

 The example on the right shoes a burred end wall on the left side. For this kind of cut, it is critical that you apply a target like the green dot stickers shown here.<br><br>
