Cura 3.2.32 for Windows having difficulty with 100MB+ files
Open, NormalPublic


Cura LE Version: 3.2.32

Operating System: Windows both 7 and 10

Printer: Taz 6

Tool Head: Stock Extruder

Description of issue: Customer is unable to load large files into Cura LE, receives an Invalid File error. Is able to load same files in Ultimaker Cura and S3D without issue. Has tried files on 3 different computers at their work and all produce the same issue. This seems to be Windows specific because when they sent files over to us we were able to open them just fine on our computers.
The specs for the 3 computers tried are listed below:
Dell, precision 7920 Rack workstation Windows 10 Pro, 48 GB ram, Intel Xeon Gold 6130 2.1GHz, 3.7GHz Turbo, Nvidia 7920 rack
Dell XPS 15 9560, Intel i7-770HQ @ 2.80 GHz, 16 GB ram, Windows 10 Pro
Custom tower workstation, Gigabyte board Intel I5-8500T, 256 GB ram, Windows 7 professional

Steps to reproduce: Based on customer experience you should just need to load a very large file (100MB+) into Cura 3.2.32 using Windows computer. We were unable to reproduce using Linux computer in office.

Customer sent in several log files, I have included the most recent one but can also include older ones if that would help just let me know.

@Galadriel Can you get us an example file to test with?

We have also seen compatibility issues with multiple versions of Cura installed on a single computer, would they be able to uninstall other versions and clear cache?

@karrad ,
This is most probably numpy-stl or numpy problem.

It is probably due to 32 bit build, instead of 64 bit build (?).
