I went to get something to eat and ended up at a diner across the street from the 'Space with two other Makers. One of the guys, Ed, knows quite a bit about the Makerbot 3D printer. When we got back to the 'Space, he analyzed the problem. He took the left extruder apart and realized that there was a missing washer on the pin that pushed the filament to a gear. The missing washer allowed the gear to slip on the filament. We added one washer and tried another print. It worked great.
Here is a picture of half of the auger that I printed. I realized after it started that I already successfully printed this piece and did not need another one. Oh well.
In other news, I brought a bent metal piece that attaches to my camper to the space. Dan, the blacksmith, helped me straighten it out. Cool!
Another great day at the Makerspace.
