You can think of the machinekit controller as a servo drive that has a stepper motor output. So there will probably be overshoot on any deceleration. If you have the computer for it, the Clearpath utility is very nice for capturing data. Don't forget that the Clearpath motors have their own decel setting, which they will enforce. You don't want to hit their decel limit on a multi-axis move, because the motors will be out of sync until the one that is behind catches up. I thought about getting their motors for my mill, but I feel like they skip over the power rating that I would like.
