Sorry me old China! (Mate)
I've done it myself, too much cut on endgrain even with the sharpest plane in the world will dig-in and cause misery, heartache and in my shop at least, "very blue air" from the adult expletifs, (good job my wife can't hear it over the noise of the machinery!)
I use a sharp chisel or carpentry knife and rule to pre-score my exit edge exactly on the marking line, just deeply enough to prevent endgrain tear out. A piece of scrap as a spelch block is a good idea too.
I use no more than 1/16" inch cut per pass, going down to 1/32" for the final three cuts.
Cutter speed is also crucial, I use a piece of scrap and make several passes at different speed settings using as slow a feed rate as I can without burning the workpiece.
Planning is also a useful tool, if you leave a square board over dimension across the width, you can joint along the grain to take care of any annoying little tear outs.
