Sounds to me that the router is moving too slow. When I router material by hand, I would move the router about 70mm per second or 4200mm per minute (about 3" per second or 15ft per minute which is kind of slow for a 1/4" bit). With a router speed reduction to 10000rpm, I would still move at the router at a pace of 1700 mm per minute.( 5 1/2 ft per minute or 1" in per second). Any slower and you risk scorching the material.
At 10000 rpms. you're moving at 10" per minute or less than 1" per 4 seconds, just too slow.
