Cura closes after 'Loading UI' - both version 4.11.x and 4.12 after upgrade to RTX 3060 ti

Posted · Cura closes after 'Loading UI' - both version 4.11.x and 4.12 after upgrade to RTX 3060 ti



I haven't had Cura opened on this machine since I installed version 4.11 some months ago . Today I wanted to slice something again, but Cura ran through the 'Loading <various plugins etc>', but as soon as it came to Loading UI, the screen turned white and then Cura just closed. 


I did a quick google search and found some vague answers regarding Nvidia drivers or something and thought that maybe, since I just recently upgraded to a RTX 3060 Ti in this machine, maybe I should just upgrade drivers for both Nvidia and install the latest Cura (4.12), but no dice.


The contents of the Cura/Stderr.log and Cura-4.12/cura.log is attached. 


Any help is appreciated as I am pretty screwed right now when it comes to slicing anything... 


OS: Windows 10, 64bit running latest (current as of this date) updates, 64GB memory, Asus RTX 3060 Ti, running Nvidia Studio Drivers version 472.47

    I've been doing some more searching and stumbled over this reply on github for a similar issue: 



    Turns out, it can be because I had "GPU Tweak III" running.. which I installed when I upgraded the GPU to tweak fan curves... sigh.. I hope this post will help others as well. Exiting GPU Tweak let me immediately start up Cura..

      • 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
