Lorie -
I know you are using SCAL 3 but which version? Some of us have had issues with the latest release - that is why I am asking.
Are the lines that you are scoring a different layer so you "cut" them at a lighter pressure and then go back and raise the pressure and cut out the box? If you do it that way, you will have to cut WYSIWYG so the scoring lines line up with the cutting lines of the box, but you can move the image down to the bottom right of the screen mat and that way you can set the origin at the bottom right of the paper and not lose room I hope that made sense. I am just wondering if you are trying to score and cut at the same time
And if you have been fooling around with the x and y numbers, a reset is a great idea just to get things back to square 1.
We will get you cutting happily. It's always harder if you are trying to learn the machine and master a project at the same time. But I think you are getting close!
