  The first attempt at this print was a link wonky because of an issue in the grasshopper definition I was using that caused the machine to crash into the bowl. For this initial test we just stopped the print and manually extruded a certain amount, as well as manually moved the print bed to simulate what the print would have been. This experiment taught me that the speed of the movement was the most important thing for free-flowing noodles. That, and turning off the fan while it extrudes so it cools as slowly as possible. I needed to let gravity and the air do half the work for me.  The first experiment (tiny 2cm diameter version) suffered from some very stiff noodles because of the speed we printed it at.  The bottom of the bowl was a little warped as well because the print was exactly at 0 on the Z axis rather than being slightly above. This was also probably due to the extrusion factor.  The next version of the print we attempted took a few tries to narrow down th...

I decided to experiment with GCODE by making a bowl of pasta. The trick is that the pasta is going to be printed in the air and droop into the bowl from above. Hopefully without melting everything that came before it? Here's how I set it up: I used the trick with the Spiral + Intersect on a sphere I cut in half, then used the rectilinear fill definition to cover the bottom of it. I joined the two curves to make a sort of imperfect (and very tiny) bowl. The "spaghetti" is just two other curves I projected in the space above the bowl. As it prints, I'm hoping it all spirals into the bowl below like noodles that have just been thrown in there. I also took a look at what this might look like with 0.5mm wide pipes. From there I just put the curves into the gcode generator and tried it out in NC Viewer to make sure everything printed in the right order. The organization by Z axis made this process easy to set up. Here it is on the printing bed as well.
