Try braking. This is from memory so might be all wet... If you just turn power
off, the motor coasts to a stop. But supposedly you can send the motor a speed 0
command, I think, and the motor stops right then, frozen in place. It takes more
power, which might be an issue if you're on battery, but not a lot more. Steve
H. talked about it recently, either in .robotics or in .rtlT, not sure which.
Hope that helps.
