[3.4.1] Cura back to windows and crash when add printer

[BugsBunny1403]

I have a custom printer settings work on cura 3.2.1 but with upgrade to 3.3.1.
The printer is an EXP3D, the builder provided configuration files for version 3.2.1 but I think with the changes in the machine manager a variable must be wrong and crash cura.

Can you provide the 3.2 data folder so we can investigate?

[fieldOfView]

Also provide the configuration files for the printer (is they are not included in the 3.2 data folder)

I loaded up those profiles and got the same error. The mistake comes from the definition file. It names a preferred_quality metadata entry, but that should be preferred_quality_type in the more recent Cura versions. As a result, the preferred quality type remained normal and this quality type is not available for that printer.

I've made a fix so that Cura no longer crashes on this for the next release but instead swaps to an arbitrary quality type that does exist. You'll need to update the version of those configuration files anyway though. Good luck.

@Ghostkeeper. I redid the procedure described to try to solve the problem but it was unsuccessful.
I don't understand what wrong.

[Ghostkeeper]

Could you try again with Cura 3.5? The fix I made should be included with that release.
