Hi I have a `Excellent` balanced, full battery charge and auto tuned Ronin S, but I can hear the roll axis motor making a very slight noise. Is this normal? I've also expirenced some violent vibrations on either the tilt but most likely roll axis. I'm running a Z6 with a 50mm 1.8, so it's not very heavy however the auto tune has tilt at about 40, roll 25 and pan about 40.
