The skeinview-output of a skeinforged lego brick consequently shows no raft. Is this intentionally or do I miss a crucial point?

The bit about disabling rafts causing things to center around the origin was driving me absolutely crazy! I thought I'd screwed up my profiles somehow or something. Thanks for that detail! Aha!

This post came just when I needed it. I'm still fiddling though.

Biffle Sun, 19 Jul 2009 18:35:23 +0000 http://blog.thingiverse.com/?p=520#comment-1037 Raft tuning is tricky, and two of these settings are interdependent. 1. "The Base layer thickness over infill thickness is the speed of the print head relative to the standard feedrate." This also increases the thickness as it decreases speed. 2. "Making the nozzle lift less than one standard layer (here it’s 0.75 of one standard layer) means that the nozzle will not raise up as far as it would for a standard layer." This decreases thickness without affecting speed. So this appears to produce a layer 1.5x thicker than a normal layer (2.0 x 0.75), but printed more slowly. Right? A normal human would have provided "base layer thickness" and "base layer speed" knobs, but Skeinforge has its own notion of how these things should work. :-) Raft tuning is tricky, and two of these settings are interdependent.
