Hello Harp, As of now Cutting master will not play nice with X7. Right now you would need to export and bring into Graphtec Studio. We have not received a release date on the update for CM3 yet. I would recommend using X6 for now as it does play nicely.
I know this doesn't help, but figured I would respond to let you know.
Have a great day!
Matt
