Just wanted to come back here to post the results and close the loop. Overall, I was able to tune things and get things looking good. Here are the after pics https://imgur.com/gallery/Ogqr8lM
I did switch the order of the walls.
I printed the pressure advance test here https://forum.duet3d.com/topic/6698/pressure-advance-calibration/18 and adjusted accordingly. This made a nice improvement.
I lowered my print temp to 230. Might play around a little with this just to see.
I turned off combing. I did this more so because retraction on this extruder is tiny.
I also lowered my flow to 98%, lowered the speed of the walls to 60%, and turned on my cooling fan 30% after layer 3. For bridging I jumped the fan to 100%.
I've still got some slight ringing, but I'm going to tighten the belts a little and see how that plays out. They seem like maybe they are just a touch loose.
Just want to say thanks to @jens55 and @Phaedrux . Your tips definitely helped.
