@Claymore I have no clue, I was just lucky I guess I started with several cuts on max speed and I was getting lots of fuzziness. Not that plenty on plywood, bud especially on paper and tape under it, that it was quite hard to see narrower patterns. That drove mw crazy for some time. Then I lowered the stroke speed approximately by half and it was a whole new level. Lines were clear and I was able to clear almost all plywood tear out by tracing the cut out spots so it needed no sanding.
