Hi,
Yesterday I converted my board into Gerber files and when checking it in the Gerblook.org website the Soldermask was wrong.
I made a circular board defining the edge cut and that gave me the mistake. Gerblook presents me the edge cut correctly.
I made then a test and , made the board on a square edge cut and voila the board hat correct soldermasks (top and bottom).
So I guess I have no other choice then making a square edge cut and then manually cut out my circular board ?
thanks and regards Rainer
