That video shows they have cut makrs every FT... There is no way to make it roll in both directions when cutting - the take up reel is slow... think about it, if you were on 100 speed cutting, how would it handle it? No system is that way... Summa doesnt do it, the $100,000 flatbed cutters dont do it... it just physically wouldn't work out. If the old graphtec did that, it was only for feeding the media. Matching feeding and take up speeds isnt as simple as that.
If you're doing print and cut... turn on segment area. It will cut each segment, and roll it up inbetween. Doesnt matter if you have a 10 Ft, or 100 FT Print... it'll roll every 12" or whatever you set your segments to.
If you're not doing print and cut... I believe you can use the pre-feed and it should roll up after every pre feed. never tested it though, and dont know how it'd work for really long prints - its in the manual
