Hi there. I am having problems opening Cura on my windows PC. When I start cura I get the splash screen and then the programme stops. If I click the icon, the programme ends and disappears. Please see the output below;

Traceback (most recent call last):

Hope to hear from you soon.

Kind Regards,

    Do you have haskell install?

    (This problem happens when there is a glut32.dll in windows/system32 which isn't compattible with Cura. Haskell seems to be one of the programs that installs it there for no good reason)

    Sorry, I am asking on behalf of someone and I am unsure if they have Haskell installed or not

    If the DLL was installed on his PC by an other programme which requires the DLL to run, is there anyway this problem can be fixed?

    Is there perhaps an other version of Cura that can get around this problem?

    What would you advise?

    Thanks for your help

    Copy the DLL next to that programs executable, as that it where it should be. And then remove the one from windows/system32

    Just to confirm, there is no Glut32.dll in the system32 folder but instead a Glu32.dll in the system32 folder.

    Haskell is not installed on the PC. Are there examples of other programmes that would install this dll into that folder?

    If the programme that installed the dll cannot be identified and thus cannot be moved to the programmes executable file, what can be done?

    Are there any other solutions other than deleting this file from the system32 folder as this may affect other programmes that need it later?

    Thanks for your support

    Haskell is the only tool that I know right now. But most certain there will be others.

    You can rename/move the file and see if Cura works then. And see which application stops working after that.

    Just to clarify, there is no Glut32.dll in the system32 folder as you first mentioned. Instead there is a Glu32.dll in the system32 folder.

    Should I assume it is this glu32.dll that is causing this problem and is this the file you are referring to when you say to 'rename/move the file and see if Cura works then'?

    Well, maybe the glu32.dll is the culpit. But the error is coming from glut32. Another cause could be the total lack of OpenGL drivers, but that usually gives other errors.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
          • Thanks

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
