In Reply to: Backdrive disable for the van door motors?

Sorry I'm too late to be of any help, but sense no one else gave a programming solution (my specialty), I thought I would.
Depending on how much rotation you need, you could use a potentiometer, we actually have 4 on our robot, 3 10 turn pots and 1 one turn. If you want background information on how it works, how to program it, etc. just e-mail me at

: My team is trying to use two van door motors to lift a ball-grabbing arm. The problem is that when we cut the power to the motors, the arms come back down. Does anyone know how to disable backdriving? We think it may have to do with the torx screw on the top of the motor, but we're not sure.
: Can anyone help us out?
: Thanks!
