Every vinyl is going to be different and also the blade depth / type of blade will also make a difference. But for a start I have a 60° in my Summa right now and my settings were in the attached screenshot. I did my contour cut first and removed the material and weeded it out and then put the material back in the machine and did my perf cuts, so the pressures are a bit lower than do it through the vinyl and backing. Again, all of your settings could be completely different than mine.
