-I have a model split in Rhino to 2 STL's -Loaded in Cura - Dual Extrusion Merge - Looks perfect in the NORMAL view. -but the LAYERS view looks wrong and I know it wont work. Any insight about this would be appreciated....... does each separate half need to be a closed object on its own?? This same model has printed successfully many time as a single extrusion... thanks
