hello, im new to all this and i have a question about Cura. i have a character model that i sliced in zbrush into multiple parts, i think had to import each part separately onto the bed in Cura. a scale them, and separate them so they do not overlap, and then hit "slice". it just gets stuck slicing and there is no progress. is there a reason it wont do it? is it because i have multiple objects on the printer bed and it cant compute it? maybe a setting?
