Bosch 1617EVSPK router help
The hole in the router table isn't big enough for the bit so you have the entire bit above the surface of the table. You need to put a different red insert in the table and lower the bit so the end of the curve is level with the surface of the table for a typical round over. You CAN raise your bit up and make a little flat below the curve on your workpiece, but taking all that off in one pass is asking way too much of your bit, it would take about three passes to remove that much wood.
In woodworking there is always more then one way to accomplish something.
