Re: articulating arm help

There are several ways to solve your backdrive problem (that's what it's called)

The mechanical solution, guaranteed to work, would be to replace your CIMple box with a wormgear. It cannot be backdriven. This is the same type of gearbox as comes preinstalled on the window motors.

A simple software solution would be to switch the jaguar controlling your CIM from coast mode to brake mode. This is likely to be not 100% successful, however.
