Hi I am presuming that with a new printer there is no need. But after several years I did recalibrate. I noticed that dimensional accuracy on x/y axes had deteriorated and yes, as a mechanical machine gets older things wear so not surprising.
I do not have a UM but I guess the process is the same. You will find the e-step parameters in the firmware and need to change those. It is a bit suck and see until you get there. Print a straight line, say 50mm, and measure it. This will give you a % error. Change the e-steps and reprint. Repeat until it is spot on and then repeat along the other axis.
That is one way of doing it but lol my memory just clicked in and I did it a different way. Instead of printing I just moved the print head 50mm, using my Repetier Host print control software, and measured the distance by marking the nozzle position on a sheet of paper, before and after the print head move. Now this is faster but not easy to get accurate - just the width of the pencil line --> edit
marking the position
is enough to make it wrong and where you mark the paper against the nozzle, which is >.4mm,can be different on the two markings. But take it carefully and it should be good. And then print a line to get verification.

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.
