Cura 4.7.1 VERY slow to load


Recommended Posts

Posted · Cura 4.7.1 VERY slow to load

Cura 4.7.1 was running fine.  I installed Cura 4.8 and 4.8 loaded and ran VERY slow.  More than 5 minutes to load the software.  Loading model files, rotating objects, etc. were painfully slow.  I tried 4.7.1 again and it now has the same issues. I uninstalled 4.8 and 4.7.1 and re-installed 4.7.1 and it still runs painfully slow.  I ran Creality Slicer, which is based on a Cura engine and it runs fine.  How can I get Cura 4.7, 4.8, or any other version running again on my Windows 10 desktop?

    Did you ever get a solution to this problem ? My PC recently went through an update ( Windows 10 ) , before the update Cura 4.8.0 ran fine, now after the update Cura is very very slow to the point I can’t use it.. yesterday it took half an hour to load !!! But today I tried turning the wi-fi off on the laptop, and hey presto Cura runs fine, no stalling, it runs as fast as it once did !!! Very confusing

    Do you have a network drive mapped to the driveletter X:? If so, try mapping it to a different drive-letter.

    I do, I will try that, but it was working fine before the update, and the X drive has been there for months 🤔

    It is an artifact of the buildsystem. The source files are on a drive labeled X: at Ultimaker, and for some reason Cura keeps looking for the files in their "original" location before using the files installed in your program files folder. If there's an inaccessible drive X, each file will result in a timeout after ~20 seconds or so before continuing. There are many files.

     

    Why X:? Because it was deemed less prevalent than the previously used 😧 drive.

    The D drive used collide with removable drives, which caused a similarly annoying issue that Windows told the user there was not disk in drive D a couple hundred times.

     

    I'm not quite sure why the buildsystem doesn't use an ntfs junction instead of a driveletter. That would forego the entire drive letter thing. Better still would be to stop Cura from trying to find the files in their "original location" in the first place.

    This shouldn't be a problem for 4.9.1 anymore
