I was talking about the motors. Just seen the mods for shrouds to do active cooling on the motors and the talk of adjusting the voltage to the stepper motors to the lowest point where they don't miss steps but run cool. Didn't realize the drivers on the Rumba board would be potentially more of an issue. But now that you mention it I've seen designs for shrouds and mounts for the electronics too just not any threads on here about it.
