(Is it right for me to submit this issue here? If not please let me know)

All versions of Cura are in an unresponsive state.




I did the following to solve this problem, but it didn't work:



Is there anything I should do?
Let me know if there is any information I need to provide!

Thanks in advance.



Printers I use: Ender 3, Ultimaker 3, Adventurer 3 (333...? lol)

My System: Windows 11 22H2, Cura 4.13, Cura 5.2.1

    Hey @Kamilake,


    Welcome to the Ultimaker Community 🎉
    You are welcome to post your problems here. It's also quite common to post them on the Cura Github. It's easier to find duplicates of your report there. 

    I have a couple of questions to narrow it down.

    1. Do you have multiple monitors? Does Cura start if you disable one of the monitors?
    2. Do you have GPU Tweak OSD overlay enabled? Does Cura start if you disable that software?
    3. Do you have a Ryzen CPU? Can you try this workaround? https://support.makerbot.com/s/article/1667412437627
    4. Do you have the Nahimic audio enhancement service enabled? Can you try this workaround? https://github.com/Ultimaker/Cura/issues/12102#issuecomment-1157907665


    If this is not the case it might be related to windows 11. We have a number of reports of cura slowing down on windows 11, but haven't figured out why yet. My Windows 11 is running just fine. You can read more about it here. https://github.com/Ultimaker/Cura/issues/13820

    Sorry to resurrect an old thread but this may help out somebody who has the issue of Cura not loading and sitting on a white screen "not responding" when using a multiple monitor set up on a Windows PC.


    Firstly close Cura - kill it in task manager if necessary


    Open the Cura folder in your profile - C:\users\<username>\appdata\Roaming\Cura\5.4, typing %appdata% in the windows search box will get you to the Roaming folder, the version of Cura may be different to 5.4 depending on what you are running


    Open Cura.cfg in a text editor


    In the [General] section at the top look for the the entries for window_left and window_top, delete these two lines then save and close the config file.


    Cura should now open correctly


    The cause for me was that the window_left value had a negative value due to me dragging Cura to the second monitor and I can only assume the program doesn't like negative values for screen position or it was too far out of range, removing the entries causes the program to start on the main monitor in full screen and everything works correctly. This is the same for Creality slicer which is Cura based as well.


    The work around for now is to not to use my second monitor to run Cura and hopefully a fix can be coded into the program at some point but at least I can fix the error manually to avoid having to reset the program totally 👍

    If the above works for you, then uncheck the "Restore window position on start" checkbox in the General preferences. Cura will then no longer use those two lines.

      • 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
