· Layer shift only when printing multiple models
By changing the way you print you put more stress on the Y axis and it is slipping. But the root problem is that one of the pulleys is loose.
There are 5 or 6 pulleys on the Y axis - you need to tighten the little set screw in each one. Tighten the hell out of that little screw - so much that the tool is twisting almost.
usually the most important one - the problem one - is the hardest to get to - one of the two pulleys on the short belt: either the one on the stepper motor or the one just above.
You might be able to tighten the one on the motor without removing the left rear cover but if you do have to remove the cover it's only one or 2 screws (depending how old your printer is).

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

Thanks a bunch! We'll try tightening everything next time we get a chance.
