a stepover of .01 is 5% of bit width and will account for major time in carving, i start at .025 or 10% and some times run 13% and sand a bit.
i have bob cad and have never used it as i am an aspire fan, that said you can still learn a bunch about carving on vectrics forum

there is also a gathering in november in pittsburg, it would do you well!!
the other issues are acell and feed relaionship and can be adjusted, kinda like a car racing to a curve, when to slow down and when to speed up in order to have smooth inertia around the curve
i will post my ini for you in a bit
