Quality issue. Vibration/ringing?

[mattanonymous]

I've been working on fine tuning my i3v 10in and have the e steps configured, everything's tight, and the hexagon is at about 200C. Unfortunately, I'm getting the following artifacts when printing and was hoping you guys might know what's up.

As you can see, some areas are super smooth while others have what looks like there are vibrations.

Thanks,
Matt

PS There's also severe z-scarring on the other side. I assume this can be fixed via retracting on layer change, but I haven't tried that yet. Here's a pic of that https://goo.gl/photos/drgo5Kfb3hSwZC6H9
