[UM2] Does the firmware store values in EEPROM?

Does the UM2 firmware store any values in EEPROM on the board?

If it does, are they completely reset by the Reset to Factory Defaults menu item?

I see some strange behavior on my UM2 after switching back and forth between stock and @tinkergnome's firmware version and now I wonder if there is something in EEPROM that causes this...


Best regards,

    As far as I know yes, thats also the reason why you should always do a factory reset after changing the firmware branches, to clean up old or "foreign" values.


    But @tinkergnome can tell us more I guess......

    found it:



    A factory reset marks the stored settings as invalid and loads the default values (at least that is how it is intended to work 🙂).

    The runtime statistics are preserved.

      • 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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
