Yeah. I've read that kind of thing before. Although that is correct and accurate. On my machine I changed from full step drives to microstepping, due to resonance problems. When I cut a circle out of some material with the old drives (full step), you could see small ridges where the axis were interpolated to cut the circle. With the new drives (1/8 mircostep). Those marks are not visable, even under an eye glass. So for me resolution was increased (the smallest movement achievable). Accuracy is within .003" and I'm happy with that. It's more accurate than I expected it to be. I'm still fiddling with the setup, so it may get better yet.
That's my experience so far, but I'm hardly a seasoned CNC'er.
