Ok, ive manage to cut the design to calibrate and got some question following the picture (the result of the carve)
1. The Rectangle shape was OK, as you can see the pic the shape and everything was good, only the little one in the right bottom had some problem at the upper right corner.
2. The Triangle was OK to, but the right bottom corner was not right, there was a miss cut or something like that, that make the shape was bad in one side.
3. The Round shape was the problem here, as you can see (hopefully its clear enough) the shape was wrong mainly at the center area (right and left one). and because of that the shape was changing into oval.
And thats the result and the feedback, anyone had an idea what went wrong?
BTW, thanks for the answer
