I am using SignGo V.1.12 with a Desay Master XY 300 Cutter/Plotter. When doing cuts, it sometimes goes nuts. Example I had a cutout that was 5" x 60". First cut went perfect. The second cut went half way and then the roller stopped turning and the cutting head went straight across the vinyl (cutting it) until the carriage went to the far and and just jammed up against the side. I have tried different cutting speeds hoping this would help, however it doesn't matter what speed I use, I get the same results. It seems to happen 2 out of 3 times (destroying tons of vinyl). Any one know if this is a software or a hardware problem, and is there a fix.
