I agree with jmos. I personally have had problems with the knives not being set the same depth on each end. When I got that corrected things went much better. When the jointer cuts the full length of the board the cut should be perfect unless you are able to put a tremendous amount of pressure on that board. Many beginners try to “push the board straight with pressure”. The board should be pushed against the fence and gently fed across the cutter and off the outfeed table. Technique is difficult to explain and for some difficult to learn.
Is this a recent change or has the problem always been there. How long have your owned this jointer? .002 above the outfeed table should be just right. That is .002 front back and center on all the knives…?
