For better overhangs the most important thing is 100% fan. So if the overhang is below 5mm from the bed you need to adjust the cura settings. Not as critical - it can help quite a bit to print slow. 20-35mm/sec. Also having a 2-pass-shell helps (make shell thickness 0.8). Also if layer thickness is too thin or too thick this might affect things - not completely sure about this detail - but anyway .08 is a reasonable choice for layer height.
So try .8mm shell and print at 20mm/sec just for an experiment to see if any better.
Other hints about other printing issues (not overhang) are here:
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
