This is something I haven’t seen come up yet. Every cad cam system I’ve used for many years now has had a built in decrease of feed rate for cutting radius sections of parts. The initial feed rate for a tool is used on all the straight cuts, but decreases for any radii in the pass. This technique is used on mills, plasmas, and water jets to maintain the cut quality. Is that a feature that the Easel development team has considered?

Maybe. Your reply prompted some research into just what’s possible with grbl controls, and it looks like someone developed an algorithm for it. It may be happening but isn’t being displayed. I admit I’m used to seeing everything displayed on cnc machines, but this isn’t really the same as the machines I normally deal with.
