Follow up: I went ahead and changed the X and Y max speed change from 15 to 10 and the X from 10 to 0. I haven’t tried 5 on the X-Y since I got the impression that may be to low. If you guys think it would be ok then I could and see.
The changes do seem to really smooth out the printer without a noticeable speed sacrifice. It didn’t seem to do anything major for the ringing issue but may have helped a bit. A print at 2000mm/min is pretty good.
One thing I haven’t tried yet to see if it helps is printing more shell layers. I am at 2 and maybe it doesn’t like that. I am not sure of the actual wall thickness since it is just an STL. However when I made my own sample I gave it a wall thickness divisible by the nozzle width I have set (.4) and that didn’t make any difference. Anyway, I’ve learned a bunch more so thanks again!!
