I am doing work for a person and I have designed an item for him, but when I loaded the .gcode file onto pronterface, I get 2 random cubes in one of the layers, hanging off the edges of the design. they are not in my OpenSCAD design at all, and I don't know if it is how Openscad exported the STL or Slicer sliced it but I need to fix it soon so I can print it off. I do have a lot of rotate extrude commands in the design to give it rounded edges, but don't know if that is the cause. Any help would be appreciated.
Thanks.
