Description
At the request of my eldest daughter I printed a Happy face. I didn't check here first to find if anyone else did one since I was showing my kid how the whole process works start to end. Of course it took 8 tries with Green ABS to get the thing to print. The biggest challenge I ran into was the behavior of the green was nothing like what I'd printed in natural ABS.
Anyhow, give it a try, I hope to see a few of these in other colors (I may do a couple myself, byt if anyone else has a go GREAT!

Instructions
Mostly Standard 3D print on Makerbot cupcake. I Used green filament ABS but had some challenges...
In skeinforge I carved the 0.30mm layer thickness, which required that the feed rate increased to 32mm/s and the Extrusion PWM was set at 245. There was still a bit too much plastic being extruded. and the finish ended up being a bit dodgy. On my next go I'm going to up the feed speed to 36mm/s and maybe reduce the plastruder PWM to 240. I left all the other Skeinforge settings the same as recommended on the makerbot wiki page for skeinforge.
If you have a chance to use this setting combo and to works out for you, please let me know. Or if you find a better combination, I'd love to hear about it.
June 25/'10 Update:
Increasing feedrate to 36mm/s and reducing plastruder speed to 240PWM worked really well. Check out the new Red Happy face image. After 3 failed attempts to get the raft to stick, I was able to get the red print done.

If you get too much plastic all around (vs only on the perimeter or only in the fill), I'd turn the feedrate up a little instead of turning the flowrate down. Or, same idea, if you get too little plastic all around, slow the feedrate down instead of speeding up the flowrate.
I (try to) set the flowrate based on my filament width. Turning it up to 255 for 2.8mm filament and turning it down to about 230 for the fat 3.0mm filament. That, in theory, hopefully, gets me pretty consistant 'hardware' behavior - volume of material per time out of the system - so I can then jus
t mess with how fast the steppers are moving.
Thanks Dave,
I did try setting the speed up to 40mm/s and was getting really excellent lines right up until the X-Y axis stopped moving and Replicator-G ceased up on my computer. I did 2 tests and Replicator stopped in the midst of the first layer both times
&
amp;gt;:o . So, I decided I'd just slow the whole thing down.
