Occasionally routing can leave burn marks on the workpiece. This can happen when the workpiece is fed through the router too slowly, but it can also mean that the bit in the router has become dull. Let a shop supervisor know if a bit seems dull. Sometimes the burning is due to build up of resin and other gunk (a technical term) on the backside of the blade which insulates the bit and allows for more heat to build up. Inspect the router bit before using, and make sure it looks clean. If the bit seems both clean and sharp, the cause of burning on you workpiece is either a feed rate that is too slow or a router bit speed that is too high.

If you are shaping end grain with a router table, use a square push block behind your workpiece to support the trailing edge and prevent tearout.
