Interesting raft problem

Ive been searching the forum to find out how SF42 can generate a raft that doesn't follow the outline of the printed part. Ive Printed the calibration cube with no problems however, when i tried to print the 3d vase that comes in the replicator g folders it prints a raft then prints the first layer of the part half on the raft half off. ive tried several different versions of SF and have run the output through repsnapper since my TZ gen 3 electronics will not run on anything else.

Ive had some luck printing raftless on my lazercut build plate but i know that i will need the raft for larger prints. Any suggestions on how to fix this?

This can happen if the STL file doesn't touch the z axis zero over the whole bottom layer.

is there anyway to fix this? i am using downloaded stl files for now since my desktop with solidworks is dead.
I have netfab studio on my netbook, can that make the nessesary changes to a stl file to make it work?

In Carve tell it to start at second or third slice until you get a clean bottom...
If you are having problems with SF you can give SFACT a try..

RepG is good to re-orient .stl files.
