· Loose Y-axis Ultimaker Original - How to fix?
There are some improved end cap designs on Youmagine or Thingiverse using screws to fix the rods.
However, my personal recommendation ist this one:
Fix them as they are fixed on the UM2, with spacers going around the rod and fixed by the (outermost) pulleys (for anybody interested: check the UM2 assembly https://github.com/Ultimaker/Ultimaker2/blob/master/um2%20assembly%20manual%20V1.1%20_english.pdf?raw=trueon pages 15-17). For having the right length of the spacers, you have to adjust everything and then measure the distances (which is actually a bit a pain). And then print them. I did that recently on an UMO with great success. The spacers are just cylinders with 8.6mm inner diameter and 0.8mm wall thickness (model sizes, already compensated for the usual rubberband effect of PLA).
The spacers should be ROUND. So for printing them maybe you have to do some quick-fix of the rod at one end (chewing-gum, washers, whatever seems suitable for just one print... )
remark for UM2 users: replacing the standard spacers by printed ones with adjusted length helps to get rid of belts which wear out at the pulleys.

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
