If the bit is high to the out-feed this is what happens. I would check again the out-feed to bit alignment. If you are using a flushtrim bit make sure the bearing is just isolated in relationship to the out-feed. This is the same thing that happens to jointer/planners (machines).garryjc said:The fence has been checked and is accurate. It is 50 mm thick and 40 mm high.
If you have the time, take a scrap piece of wood and feed it along the fence so that it cuts off the 1 mm then when the wood is just maybe 50mm past the cutter pull it away and turn off the router.garryjc said:Sorry, I should have said that I had isolated the bearing to the out-feed.
