Love this! I have been using 3m painters tape but I am going to try the heat tape. I call the 6 yds on the take up roll the head since it is at the beggining of the print. For the tail I usually waste 1-2 yards because my EOD image is a CMYK design I made. I never thought of printing nothing then rewinding. I am going to start working on 3d print roll holder for a tail roll that can be manually fed into the shaker for the ending. I will let you know how it works.
