I stuck an old 3D printer nozzle on the machine, and ran a test with a weak saline solution to test it from one end to the other. All the electronics, low and high voltage, behaved well together. I got the stretching I wanted, so all's good there.

Sorry about the lighting. I had to grab a flashlight to get a video of it and I guess I'm not very good at keeping it steady while I'm flipping switches and such.

I call this a success. While not perfect because the nozzle isn't perfect, the test went well and I got that stretching. That's the whole point of the machine, after all.

Now, to get the RIGHT nozzle, and make stuff for real. The machine still has a few things I need to do to it, but on the main it's about ready for show time!
