I've been reading as many entries in the forums as I can to get a better idea on cutting 3d images. One of the things I've noticed is almost everyone says use a 1/8" ball nose cutter for the finishing tool path. However for the roughing tool path some say use a regular end mill other say use a ball nose mill. In 3d I would think the ball nose would be the best choice, but I would like to hear from others the pros and cons of using a regular end mill for this application.
