Engraving 40 W USB Laser engraver

Hello
It´s my first post.
I bought my chinese machine on November. The time to try it is not much so I tested it engraving and cutting acrylic and it was fine.
after resolving some issues, related to work with Moshidraw 2012.
I manage to work in Illustrator and corel, and then to moshidraw, no problems with that.
The machine cuts fine, and engrave vector shapes fine, but I can not engrave fill shapes, only if the shapes are near the origin of the drawing.
I´m trying to engrave the file attached and the machine does not even starts. It makes a bump, like starting to work but then stops.
But all the other it ok.
I do not know if theres a ploblem with moshidraw, the file, I really can not understand because I´m doing it all. I even tryed to break the drawing, but it does not want to work.

Thank you

Helena
