My first planer was lunchbox style. I figured the manual was wrong when it wanted the infeed and outfeed "tables" sloped up compared to the table under the cutter, so I aligned it flat and got great snipe. Finally I went back and sloped the in and outfeed tables up as recommended and the snipe was dramatically reduced.
On my MiniMax (commercial grade) planer, I get snipe if the first side isn't flat (as it should be coming off the jointer), or if the board tips down on infeed or outfeed. I simply hold the in or out feed end up slightly and the snipe disappears.
Think about what produces snipe. When you just have one roller holding the work down, then any flex will tip the board into the cutter and create snipe. If you lift the end while only one roller is in play, you tip the board into the table, away from the cutter, and no snipe.
