I'm cutting .25 acrylic and getting this "ghost image" on the side of the table diagonally opposite to mirror 2, It does not affect the cut, but the ghost is just powerful enough to brown an image on the paper. I had this happen once when the cone was not seated properly, but it was anywhere on the table. Cone is fine, and no problems anywhere else on the table.
