i have never tried this print nor tried to print with conductive filament. I also have a ctc makerbot clone.Two things i would suggest though is one using simplify3d. it has a much more intuitive slicer slowing your printer down when printing finer detail and keeping a constant flow. The other thing i would suggest is printing the extruder mod like this https://www.thingiverse.com/thing:231310 . The extruder setup on the ctc is atrocious and i have found this mod to print with excellent results. Also Chuck has a youtube channel and printed this mod and has a good example of how much it improves the print https://www.youtube.com/watch?v=jv_tRVZrN68 . I do think i get better results on the CTC than his channel shows and i think maybe its becuase i am using a stiffer spring. Hope this helps you out Cheers!
