I did more testing. I believe there are two causes of the ripples/ridges:
1. "Ringing" (small, higher frequency) caused by print head vibrations after sharp changes in direction, and
2. Larger, lower frequency ridges caused by the infill impressing upon the outer shell.
Ringing
These ridges/ripples start intense near the sharp turn and taper off (dampen).
- Acceleration: I lowered the acceleration to 1500 mm/s2 but this didn't make any difference
- Adding several (3) extra outer shell layers actually intensifies the ridges/ripples (makes them worse) - I think because the ripples of each layer are additive to the next. However, increasing the shell thickness to 2 layers from 1 layer didn't have much impact - but it solves the infill ridges (see next)
Infill Ridges
I have been able to address this by increasing the outer shell thickness to 2 layers (0.8mm). I see in Cura there is a setting for reducing overlap between your infill and our shell layers. Decreasing the overlap would probably also help.

Here comes Cura 5.9 and in this stable release we have lots of material and printer profiles for UltiMaker printers, including the newly released Sketch Sprint. Additionally, scarf seams have been introduced alongside even more print settings and improvements. Check out the rest of this article to find out the details on all of that and more
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
