Planer snipe is usually caused by the cutter head assembly moving too much or an uneven in/outfeed tables. Picture below show an example of planer snipe.
One easy way to avoid snipe is to marry to boards together and then run it trough the planer. You must ensure that your scrap piece is longer than your good piece at both ends so that the snipe doesn't occur on your good piece. I simply taped the bottom of two pieces together and this did the trick.
Ran the boards though my planer until desire thickness.
This simple trick worked. I planed the maple piece to my desired and avoided snipe. There are other methods online but this was so simple and worked well.
