Likely you are feeding too slowly, you should go along at a pretty good clip but not enough to cause the material to split out. I will occasionally, when having a little burn trouble, climb cut the material on the first cut then the final pass the right way. Climb cutting is a good technique but you should not attempt it if you do not understand the physics.
