.obj load view has half slices at each poligon
why the .obj file load as half slices at each poligon and look so small ?
is there any otherway to convert .lxo modo file to .3ds/obj/g-code as well as 3d soft at repetier ?
You could try exporting stl instead. That is the most basic format. Make sure the triangle orientation is correct on export. Normals must face outside or you do not see them and host will complain about being non manifold.
If you are on Windows 10 you can try the repair in that case.
