I have just purchased the US Cutter SC Plotter. and Sure Cuts A Lot 3. The cutter is not cutting the right direction. I am cutting "Growing in Grace". It is 15 inches in Hieight and 120 inches long. It wants to cut it across the vinyl. I have changed direction with my mat and it does not make a difference,,,, cuts the same either way. Not sure what I am doing wrong
