Matt,
So which bit works best for you? On my board I used a 60 and it seemed to work fine. What RPM, DOC and feed rate are you using?
What kind of board stock are you using?
This was my first milled board and I was totally amazed at the quality. I think it was better then when I was doing boards with photo resist and films.
