Look mom, round holes

So I finally got round to do some
print testing with Cartesio.




I started at 40mm/sec (in photo, the right hand side, and video below).

 

what !!!!!!!!  4mm round holes.
I normally get oval shaped holes, roundish at best.

next, did 2 tweaks in skeinforge and ended up with left hand side.
Oh, I am SO gonna tweak some more !!
