I'm having a problem with Cura locking up after both sending a model from Fusion 360 and from exporting it to STL and loading it up manually. This is occurring in 3.0.4 but was also happening in the previous version.
Basically, after the model is imported and sliced, attempting to navigate in the viewport or adjusting the model in any way can result in this issue occurring, forcing me to close Cura and restart. Sometimes my Mac will crash completely if I don't force close Cura myself.
I don't think there is anything wrong with my Mac (it generally runs well) and its not ancient either (16gb memory, 3.1ghz i7). The STL model appears fine as well; I've had a look at it in Blender.
This doesn't occur all the time but happens more often than not and its really annoying. Currently I have to just keep restarting Cura until I get an instance where it doesn't lock up. Any idea what could be causing this?
