image to gcode

I do simple test to flow Bitmap image.

1. I trace white/black edge of image (image is 1 color B/W lineart) to get edge
2. I folow that traced outline/edge and for each pixel I do next steps (loops)

A. Start loop of radius from 1 to some max limit
B. Start Angle counter from 0 to 2PI
C. Check if Circle with loop radius with center of radius and angle from loop fit's on bitmap black area
If circle fit's then remember that radius and angle
D. finish all loops

Remembered radius and angle should point to just right point for cutter.

It's should work but I got some strange errors and still can't solve it. Just some pixels are seems to be noisy. The principle seems right one.
Just see sample... The white should be router path but isn't clear. I do not now why

I got 1'st code output.

It's not smothed and hughe.
Only smothing is done with G64 P0.1 Q0.1 ie smothing by EMC itself.

Now I had to do smoothig of cone and for now I had no idea how to do that. and to remove path where is double. (As I trace contour I got in near all points double trace

Here is simple cutout. The image is not so good than real part is.
