I don't know anything about the 270D, but I have the Brother 8500D. You can "edit" designs on-screen by using arrow keys. Can you do that with the 270? It shows measurements on the screen on the 8500, so you'd be able to get them centered. If you can't do that, you'll need some kind of embroidery editing software like Embird so you can do it on your computer and then you'll need a reader/writer box so you can write the design to a card that fits in your machine.

I have the 270D. What I do is use a medium font, and after I have the name typed in, go to the bottom right hand button on the screen, sorry can't remember the name of it. There you can choose where on the screen to put the object. I put it as far up as it will go. (if it's too big, this just doesn't work) I stitch this...then after it's done, I do the same with the last name, moving it down the screen. On the screen there is another squre looking button that will actually move the hoop around the space the stitching will go, so you can adjust as needed. I would suggest a test run on a scrap first, as my directions are lousy! Sorry
