I've made a 9H-printing model tonight, and only a little part of it failed (because a support dropped off). I want to reprint only that little part.
How can I do that in Cura? How can I tell Cura to generate a gcode file so only that little part (inside the transparent cube below) will be printed?
I've placed the model upside-down on the Cura plate to "cut off" what was well printed. I've made a simple 3D cube model in Blender and placed it so it intersect with the part I want to print (I've set the "mesh type" of that cube to "don't support overlaps" for that). I've tried using "Mesh fixes: disable Union Overlapping Volumes" and the "Merge meshes" option, but the merge aligns the cube origin and the model origin (which I don't want).
What's the proper way to do such partial printing?
