Retract Before Outer Wall Does Not Appear to Add Retract...

Yes, but the travel move to the outer wall from the wall next to it is only 0.4 mm long and this is shorter than the Retraction Minimum Travel setting so no retraction is done. I just noticed that setting is currently not visible (it was disabled a couple of months ago). I will ask the UM people what's happening with that.

Ah, thank you for the information. I did a bit of searching, and I see that the "Retraction Minimum Travel" setting has been explicitly hidden due to several bugs:
Adding a line to the appropriate Cura quality configuration file in order to set the value of retraction_min_travel (e.g. retraction_min_travel = 0.0) seems to add the retraction to the G-code, at least in the test scenario that I provided in my prior post. I'll try to test things later today.
Incidentally, I have a Creality CR-10 printer, and I have been trying to resolve a problem with a skin seam that appears when the nozzle moves to the outer wall. This problem does not appear to occur in Cura version 4.0 and prior (the seam alignment behavior appears to be a bit different in versions after 4.0, regardless of the "Z Seam Alignment" setting, which makes the problem more apparent). It appears that I might not the only person who is experiencing this problem (https://github.com/Ultimaker/CuraEngine/pull/1108#issuecomment-555751196):

Is there any information as to what this bug actually is? I think the disabling of this in the fdm printer is the culprit of why we can't get the creality printers to print as well as v4.0 with our old profiles and the legacy definitions I created for 4.3. I was hoping this would be fixed by the 4.4 release.

In the Cura 5.8 stable release, everyone can now tune their Z seams to look better than ever. Method series users get access to new material profiles, and the base Method model now has a printer profile, meaning the whole Method series is now supported in Cura!
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
