· Bed does not find Z-axis home position anymore
Hi,
and welcome to the forum.
When does the bed not stop any more? When it goes up or when it goes down?
When you first start a print, the bed tries to go down first. There it hits the limit switch - it does a kind of bounce movement, first triggering the limit switch and then going a bit up and down again. Then it waits for the nozzle to heat up. After that, it goes up and stops a few cm before the nozzle. There it waits until the nozzle starts extruding some filament and then the print starts and the bed goes all the way up to the nozzle.
Where does it exactly fail?
If it is the first - when it goes down, then most likely the mechanical limit switch at the bottom might be dislocated or the switch's arm bent so the screw underneath the bed does not touch it when it reaches the bottom.
When it is at the top and the bed tries to go higher, then you might have flashed the wrong firmware. If you have an Ultimaker 2 and would flash the Ultimaker 2 Extended firmware, then the printer thinks it is taller, and would try to move the bed further up.

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.
