Folks, I'm new to the forum, and have just got an SC540EX print/cut (refurbished). Having a problem with the thing not wanting to cut the same path as I tell it to. It acts as if the kerning is different for the cut than the print. Both will start at the same point, but by the time it gets 8" or so over, (on a contour cut), it starts to cut differently. Keeps getting off more and more the farther the cutter travels. Have tried auto adjust, and manual adjust. According to the marks and where it cut, the thing's dead on. Using Signlab 9.1 print & cut. T-100 cabled to router. Software issue, hardware issue? Ideas?
