Initially I was brave enough to just use a normal circle on the edges_pcg 
layer, but that didn't work out. I sent the .dsn file to the head of 
freerouting.net and got told that it only supports closed polygons and arcs as 
outlines, but not full circles.

So I ended up with using 4 arcs.

Step 1:

How are you defining a circle using the "edges pcb" layer?  I assume you had to 
enter 4 quarter circle arcs?  Or other?  If arcs, make sure they are connected, 
exactly down to the exact matching end coordinates.

I can provide subsequent steps as needed.

I was planning to get the boards cut as a circle.

It is possible to work around this with a polygon as the outline just so the 
autorouter works and then replace it with a perfect circle. I'm just not sure 
if the problem is kicad or the autorouter.

Will the board house cut a circle? if your doing it yourself just make the 
squair big enough and do the circle on the silk.
