how the heck do i get this to work. i put lube in the controller and put power to it via an industrial spring and its not transmitting power to the machines hooked up to it. i read that i was supposed to put a gearbox or a shaft in the corresponding side, but nothing happens when i do that. the machines are getting 0 power. the gearbox was a 4:1 steel with 1% damage and the shaft was a steel shaft.
