Surface Quality Downward Spiral. 6 months and still cant figure out.

· Surface Quality Downward Spiral. 6 months and still cant figure out.
I'm not sure which issue you care about. I'm not sure what you are talking about. But I see 3 unrelated things:
1) poor quality on some overhangs - severe overhangs particularly bad but even 45 degree overhangs like blue model upper lip should be better. This is usually fixed for me by printing slower - I'd dial it down from 30mm/sec to 20mm/sec just in this area to see what happens.
2) very fine stringy hairs (these are very easy to remove and I've heard several theories of what cause this whipsy things but I'm not sure)
3) Some vibrating patterns in green image (this is made better by printing cooler usually)
#1 seems like the worst problem. Could it be that your models have many more triangles/faces than your older models? Cura can only plan 16 line segments at a time so when you have 16 line segments fitting into 2mm of travel it mess things up and you get weird shaky movements.
Also it seems you are changing filaments. A lot of the newer "pla" formulations do better at cooler temperatures.
