I have the dewalt planer DW735. I’ve been using it frequently lately on hard maple and have noticed marks in the wood that i’ve seen in other blogs called “chipbeat”, which is where the shavings follow the blade around and then get caught between the blade and the wood causing unwanted indents which almost looks like minor tear out on the wood. The blade depth on this planer is not ajustable and neither is the chip deflector. I noticed the chip deflector was bowed so i ran a screw into the housing to push the chip beater closer to the blade. The “chipbeat” is reduced but has not gone away. Has anyone else experienced this problem in the past?
IT isn’t DC problems either. The DW735 has a built in blower so in my setup, the chips are blown into a canvas bag which is regularly cleaned. I’ve tried just letting the chips blow out the port which doesn’t seem to have an effect on the degree of chipbeating.
Secondly, I’m running new aftermarket carbide blades in the planer aswell. So it isn’t a dull blade issue. Any help is appreciated.

knife size?
Are these aftermarket knives exactly the same size as the originals ? Width & Thickness? There might be some geometry that is messing things up.
I'm not familiar with the specific planer that you've got, but the problem is common to all machines. The chips are sticking, not to the blade, but to a roller in the outfeed side. Possible remedies:
Clean the rollers well and wax them.
Make sure the DC is unobstructed.
In some weather conditions, static electricity can cause chips to cling where they usually don't. Try slightly wetting the wood before passing it through.
Things To check
Check that the duct is clear, that the blower wheel is intact (they can get worn away), and that the drive belt for the blower is working.
PS: A note from BruceS has informed me that the blower on a 735 is directly driven off of the motor, so there is no belt to check.
