Strange cylindrical base on printed rounded objects?

Even higher up the quality is bad. That higher up section is caused by printing with not enough fan. Is this ABS or PLA? If ABS and you want good quality you really need to enclose the printer like the Zortrax. If PLA then you just need more fan and probably lower the printing temperature also. What temp are you printing at?
The bottom area that you spoke of is usually called by the build plate being too hot. I will get something similar at 70C but it's usually perfect at 60C for me but if you enclose the machine you might want to go a little cooler or maybe better - make sure the fans are at full power by the 2nd or third layer. In cura look at your fan settings and make it go to 100% by 0.5mm to .7mm (this is for PLA, not ABS). Also double check this by going into the TUNE menu while it is printing and make sure the fans get to 100% by layer 3 as your material settings on the printer can override the cura settings. For example by default I believe ABS keeps the fan no higher than around 50% and I would probably even go to 30% even if the printer is enclosed.
Oh - and white is more difficult to print with for some reason - it tends to melt at a lower temperature and so you probably want to print it 10 or 20C cooler than typical. Again, assuming this is PLA and not ABS. So either try a different color or try printing at say 200C. In fact I'd try an experiment where you print just the bottom bit of those pins (and then cancel the print) with 100% fan and 0% fan at 210C, 200C, 190C, 180C. And print slow - like 35mm/sec just like the zortrax does (I think it's like 20mm/sec!).

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
