Occasionally routing can leave burn marks on the work piece. This usually means 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 back of the blade insulating the bit and allowing for heat to build up, make sure to keep bits clean. A final possible cause of burning wood while routing is taking passes that are too slow or setting the router bit speed too high. A good rule of thumb for setting router bit speed is the larger the cutter the slower the speed. Set the spindle speed adjustment to around 20000 RPM when starting out and you can adjust as needed. If a specific cutter is marked with a recommended speed start with that.
