First of all, cutting the Recollections paper at that pressure is not high. That is about what I use to cut card stock roughly that weight.
I am guessing the issue may be the font itself. As you know cuz we say it a lot
, all fonts are not created equal - some cut much better than others. Have you looked at the nodes to see if it is node intensive? How large are you trying to cut it. All of that could be playing into the results you are getting. I would start back with getting clean cuts on simple shapes to be sure you have the blade set correctly and then try a font or whatever you need/want to cut. Try cutting something you know you have cut before successfully.
Is your mat sticky enough and are you brayering the card stock down? Also be sure, even though you have a new blade, that it is not chipped.Every now and then a new blade can be defective. It doesn't happen often, but it can happen.
