Trouble printing marble machine

[Argus]

Has anyone tried to print this http://www.thingiverse.com/thing:795952

I have tried and always have extra tracks right through the middle of various parts of it. I have also tried all the rear options within S3D.

I tried a few days ago and it seemed to be fine, but I ran out of filament about 3/4 of thew way into it. I'll probably try again this weekend.

Does your gcode preview show problems?

Maybe it had something to do with the fact that I printed @ 0.5 full size.
