I'm using Windows 10 with SCALP 4

I have not used the pen tool. It cut 1 design right and I cut it again and it rolled out about 2 feet of vinyl and cut a line in it. The carriage just goes crazy. I changed the USB cord. I rubbed it down with anti static to rule out static.

Out of the blue, my Titan 2 stopped cutting correctly. Now the vinyl feeds and starts cutting then it stops OR it cuts random lines in the design. Any ideas what the problem could be. I use scalp and have never had this problem before.
