I'm having a few issues with my new Mh-721 1. Sometimes, the plotter won't finish cutting i.e, leaves out the circle in the Capitol "R" 2. Can't seem to get the right pressure on thicker tshirt vinyl, right now I have it on the highest pressure and its still not cutting all the way through in spots, (using a 60 blade) 3. I'm using Imprintables glitter vinyl and it seems IMPOSSIBLE to weed, it just comes apart in big uneven clumps!
