I just setup a cross-hair laser and thought I'd share some pictures. Total cost was around $13. Once complete and mounted, I set the cross hair at the point I want x and y to zero, then enter one of the custom C codes that I have setup to move x and y the distance to where the cross hairs were pointing. I can provide more details if anyone is interested. The picture of the cross-hairs does not do it justice - the laser was adjustable and looks pretty good with fairly tight lines.
