How do I tell Estlcam to make 90 degree inner cuts?

Is there a setting to make the corners on the red selected area come to a point and not rounded?

If that’s a hole cut, then on the bottom left of the properties window is “Overcut”. Click that, then select the corners. It will add a small dogbone to the corners so a sharp corner will fit into a round-ish hole. You can’t make sharp inside corners with a round bit, so this is how it’s done. Either that or make the corners sharp with a file or chisel.

Okay, I thought that was how it was done, but wasn’t sure. Thanks!
