I also thought once of replacing the belts on my UMO with ball screws. There are 3D printers which have ball screws for all three axis. But: Unless you really need the very last few microns of x/y-accuracy you will not see a difference, especially not on the UM2. With the belts there are actually a few issues which can be avoided by general maintenance. If you have a belt rubbing at the pulley, you might want to print your own spacers between pulley and bearing with a slightly different length. From time to time it's good to check the tension of the short belts and to adjust it a bit if necessary. I also read some UM2 users had an issue with the auto-tensioner of the long belts and they had to replace it after some time. Personally, I don't see such an effect (yet) on my 1.5 year old UM2.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
