I have my x and y done and have started on the z axis and man these ball screws move freely!

What are you guys with ballscrew conversions using to keep the z axis from hitting the table if the power suddenly goes out?
I have seen some guys using counter balances but some complain the counter balance can introduce backlash.
Someone posted up a part # for an electromagnetic brake, but I can't seem to find that post anymore.

What does the IH CNC Kit use?
Do the servos + pulley gearing slow it up enough?

Thanks,
Devin
