:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Maybe not. A few years ago I was setting up a minimill, with drivers that change between full, half, 5, or 10 microsteps (Flashcut 3.5 amp). I changed the drivers from 5 microstep setting which had worked flawlessly, to half step, and immediately lost steps on parts due to resonance. If any of your parts will have arcs, the machine will go through the "bad" spots of resonance no matter what feedrate it's run at, with possible lost position.
