Extrusion

I managed to get the extruder to put out some plastic without falling apart. After trying various things, two mods made the most difference:
1. Zach's suggestion of using a hose clamp on the Teflon / heater barrel connection worked extremely well.
2. The other end of the Teflon barrel kept slipping as well, so I wrapped it in some doubled-over sandpaper.


I cranked up the heat and pushed some filament through. Here's the result. When stretched out, it's about 14".


Unfortunately, I seem to have destroyed another thermistor in the process. On my next order, I might have to stock up on a few.
