We I’ve posted about this previously and haven’t had improvement or a solution, so I wanted to mention it again since it’s still happening to me, but the result is slightly different. It was previously a burr type of thing but now it’s a bit more smooth - but still an issue of not cutting all the way through smoothly and always in about the same place.
Whenever I cut a circle like the piece you see below, it always leaves an odd burr or rough place somewhere around the 9 o’clock to 10 o’clock position.
Today I even ran two passes on the outside cut. But the circle still took a small tap to fall out rather than falling out on its own - so there’s clearly an issue somewhere.
