You d/l a manual for the software from signwarehouse, it's in pdf form.
You need to in fill/stroke I assume, never messed with wireframe, as I always create everything except text in inkscape then import into the cutting program, which I now use signblazer, both of these are free.
There should be a serial port on the cutter next to the usb port, you may try that but I was having so much trouble, and wasting so much vinyl until I just went straight serial port.
Hope this helps! Alan
