DXF files Crash in Linux from Openscad

In the EXP Linux version, in the Spindle setting for CNC machining, when I take a drawing done in Openscad and exported to dxf, when it is put into voxelizer, the program crashes immediately. Is this an incompatibility between the exported dxf from openscad, or is it voxelizer? I tried the dxf from Zmorph for the rocket stand, and it did open.

So what’s up? Any ideas?

Thanks, Eliza
