Factory reset every time power is cycled


Recommended Posts

Posted · Factory reset every time power is cycled

I decided it was finally time to try to upgrade the firmware (4.3.96) that got stuck in one of my printers several months ago. It has never been able to upgrade the firmware since and has the bug where you have to restart after removing a print. I had to change which network I was on at work to get outside connectivity. When I setup the new wifi network the wifi started acting crazy. I tried going back to my normal network. Now the wifi won't connect, it will just turn off the wifi and think there is an ethernet cable connected. The worst part though is that now every time power gets cycled the printer thinks its new out of the box and I have to go through the new printer setup. That would only be a minor annoyance most of the time, but now I have to print off a usb and when it is done I am forced to reboot because of the firmware, it's much more of an issue.

The printer is about 3 years old and heavily used. Is it just old and ready for replacement, or is this related to the firmware?

    Hi alunna,


    3 years are no age for an UM3, and intensive use isn't either, if it's properly maintained.


    I suppose, you're stuck somewhere in the step stone firmware, that was needed to update to version 5 (don't know exactly, which versions were involved there). So you could try the "unbricking" procedure, described in the linked post:




    (its: https://community.ultimaker.com/topic/20024-recovering-a-bricked-um3/ )


    and return to a working firmware version and retry the update / upgrade again (I never had any issues updating the firmware, but I ever used "hardwired" ethernet instead of wifi).

    Actually, 4.3.96 IS the stepping stone firmware, which was never meant to be used for printing, but only to make the step to 5.x. The last "working" firmware was/is 4.3.3.

      • 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
