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.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
