it’s been several years since I used the removable matte paper but I remember it being super thin, so I would try a force of 3 to start out and see if that cuts it enough to peel up but not so much that it destroys the sheet.
you might also want to slow down the speed if you have a lot of turns and corners. I always use a speed of 8, but I’ve heard other shops say that their machines can’t handle that speed. Every machine is different and so you really have to just play with the settings to find the perfect one.
unfortunately waste is just part of getting the perfect settings. But one thing that might help is to make a sheet that has several circles or whatever shape you want and make the cut lines different colors so you can have your machine try all the different settings on one sheet and see which setting works the best.
