Ah that would work - because the initial outline it prints clears the nozzle anyway.

Well currently printing another plug at 0.3 and it didn't curl !

I can see that it's adding infill at the edger of each layer - which makerware doesn't do. I think that's what's keeping it from curling.
So far I'm impressed :-)

And i remember someone replacing that purge code with the code makerware uses to draw the line on the edge of the bed.
Think that was on the simplify3d forum.
