I just got bitten by this one. I can't emphasize enough how incredibly deficient this approach is. I have maybe a hundred existing .3mf files. I want to change the starting gcode I send to the printer on future gcode files I generate. If I open an existing 3mf, it is either going to create yet another superfluous printer (which must be deleted, and the existing one activated again). Or, if I forget to change the setting, it OVERWRITES my modified gcode file, and I start printing subtle junk until I notice. And the same thing applies to material settings??? So any change I make, when I reopen the 3mf, either permanently changes the material definition, or creates a new permanent material. Having to always remember to add a post-filter isn't a great solution either. As a user and as a pro software developer, I am just SHOCKED at this. Cura must separate the idea of what's in the current project from the presets, so if you open a file, you have only a *temporary* change, just for that project file. That's what happens implicitly with the various settings that you alter for a particular project. If I save it as a 3mf and reopen, everything MUST be exactly the same, and NO permanent settings can be changed. NO SIDE EFFECTS to opening a file. You must take a specific major action to change a setting, as you do now with materials ... update material to match current settings. NOT have it happen sneakily just because you open some random 3mf. This is a disaster. So much work put into Cura, and a clean botch. Not ready for prime time.
