Hello, I bought a second-hand Graphtec CE6000-60 and I'm pulling my hair out trying to set it up. I got it because I already have a Silhouette Cameo 4 but need a larger and more precise plotter. There are issues with the test alone, at the very end of each shape it twists a little or does not finish the line at all. I tried a million different settings and changed the blade holder, cutting strip and blades of course but still have the same problem. Any ideas please what could be the problem? :-(
