Hi, looking for some impartial advice on Summa S2 plotter. I have had a Graphtec FC8600 that I have been fighting with contour cutting issues for years and gave decided to upgrade to a Summa S2 T160. It comes with OposX but I had been advised by another sign company that I should get the Cam version. I would like to use it for long runs of contour cut logos and like the idea of loading a printed roll and letting it work away, but do I need the Camera to do that? Any advice greatly appreciated!
