Has anyone done this Or do you rely on the drive to hold the spindle in position.
No doesn't happen and if you have the correct size motors the holding torque is enough.

If you have a very heavy Spindle then having a counter balance will help the motor but it's still down to the motor to hold it unless you have a break on the motor.
