graphtec has blamed our material. (3m), going too fast, rollers too close to edge etc. Us cutter and graphtec techs immediately told us to adjust pinch rollers. They have no adjustment despite others on this thread claiming they do. We sent it back and it did have a loose carrier. I knew it but i refused to fix a brand new machine. We are now stuck wondering what to do . We really need a second machine for production.
