   All The Above

   Burns from a planer are unusal, I've never experienced such a thing.

   It could be a lot of things, including those you have mentioned, although I wouldn't think too fast of a feed rate would be a cause. When you say the blades are garbage I wonder how that could be since it's new planer. At least I assume it's new. DId you buy it used? What brand is it? Dull blades could be the culprit. The fix would be to have the blades sharpened.

   I think taking too deep of a cut would tend to stall the motor or trip a circuit breaker before any burning would occur. I rarely take more than a 1/32" cut with my 3HP motor. A slow feed rate could be the cause as could inappropriate infeed and/or outfeed roller pressure. Try feeding the wood so it makes contact with the infeed & outfeed rollers but the blade doesn't make contact. Note the speed. Then adjust the cut so you are taking a light cut and note if the speed is slower. If it is slower then the infeed and/or outfeed rollers need to be adjusted.

   Slow feed rate combined with dull blades might be the cause. Most machines only have one or two feed rates. Other things can contribute to slow feed rate such as excessive friction caused by the table being dirty or coated with grease. Cleaning it with mineral spirits and coating with wax or Bostik's Top Cote could help in that situation.

   Some woods are really hard and some have a high sugar content, both types could burn for those reasons. Taking lighter cuts with these types of wood is a good idea.

   Excessive sawdust/chips around the cutter head can affect speed and interfere with the blade. Are you using dust collection?

   If your blades are garbage, that might be the problem!
