When making a cut of the outline of an eagle I am getting extra unwanted cut lines across the body of the eagle starting from the zero point in the top center of the stock. I m not sure what causes them or what to look at to fix it.
I loaded a DXF file on an Eagle into Meshcam then scaled it 40% to fit on a
piece of stock I had. The outline of the eagle cut nicely, but there were extra lines
across the body of the Eagle that should not be there.
The extra lines all seem to start from the zero position which was in the top center of the stock. I then raised my retract height and tried another cut. I got a very similar result, but a couple of lines across the body of the eagle were not there in the second cut. The results are shown in the photo below
The simulation in Meshcam shows the retract height being well above the stock, and no moves from the center of the stock.
The toolpath parameters I used are shown below
Has anyone seen this type of thing before? What should I look at to fix it and just get the outline of the eagle cut, without the scratches starting from the zero position in the center of the stock?
