Dan, your last comment about me not given up.. made me laugh, but anyway... I know that you know what your doing or I wouldn't be asking. I did the STL slicing and somehow it didn't turn out anything like yours when I put the pattern on a .75 board I had the whole four sweeps through the board. Maybe by looing at what I come up with might help by what I'm doing.. showing on the snips is kinda what I thought it would look like. (before it came up.)
