Hi! I work in a public library and manage 4 3D printers (two 3s and two S3s) which we use to print patron submissions. Patrons are instructed to download Cura, choose settings, and save and submit as 3MF files. Library computers run on Windows 10.
In the past, this sometimes worked and sometimes didn't - some patron files would open with all their chosen settings and some wouldn't. Since getting the S3's and updating to 4.8, no files have opened with settings. Attached are some example files patrons have submitted - none have loaded with their settings and I have tried both preferences of "always open as a project" and "always ask me" whether or not to open as a project.
I read elsewhere that I could open 3MF files to manually read and find this information, but I am not sure how to do this. Tried opening in Notepad but just had random characters. However, even if I could open up files manually to find the info I need (Layer Height, support, which parts of model are printing from which extruder for 2 color prints, etc.) this still seems time consuming.
I also read elsewhere that if the 3MF file is saved in another program, it will not load with cura project settings. For patrons submitting from home, this is possible, though unlikely. And I know for a fact that many of the files were done in Cura because they were done by the patron in the library and I watched them save and submit a 3MF project file. These too do not load with settings.
So, questions I have:
Is there something easy/obvious that I'm missing to get these to load with their settings?
We have 4 different printer profiles set up for each printer - is there some adjustment/interference there that I'm unaware of and need to fix?
How does one manually open a 3MF file to inspect if this is in fact a viable option?
Our workflow is based on patrons doing the work and us accepting/printing files. Not having them load with settings prevents that from functioning. I appreciate any and all insight and help!
