I'm with Lurch on this one.
Are you using the correct sized cutter in the correct sized router?.
The only thing I can think is that you are using too small or large
(diameter) cutter or that you are using a 1/4" router instead of a 1/2"
one so that the guide is the wrong size.

What difference should the type of router make? If the cutter and the
guide are the right diameter then surely the router type is
immaterial.
