The Z axis jumping suddenly is a new issue and it seems to be related to overheating of the *driver* on the board under the printer. Most people fix it by lowering the current slightly. The issue possibly is *not* temperature related as some people claim cooling the board doesn't help yet lowering the current *does* help. Anyway try adding this gcode to see what happens:
M907 Z1000
That sets the Z stepper current to 1000ma. Default is possibly 1300? I forget. Also consider removing bottom cover, printing with printer at 45 degrees (it will print at any angle and even upside-down just fine) and have a fan blow gently on the underside.
Experiment and let us know what works so I can tell other people. It's really a small percentage of people with this problem (guessing 1% but don't really know) and it's a new issue (something different about the driver chip maybe or just the hot weather?).
Strap in for the first Cura release of 2024! This 5.7 beta release brings new material profiles as well as cloud printing for Method series printers, and introduces a powerful new way of sharing print settings using printer-agnostic project files! Also, if you want to download the cute dinosaur card holder featured below, it was specially designed for this release and can be found on Thingiverse!
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.
