  1. Okay. I got it fixed, but that tutorial did not help. I had to heat it up, remove the nozzle and the fan assembly. The plastic had completely surrounded the extruder both above and below. At temperature (200C), I was able to carefully pry the plastic out (being very careful of the wires). The dental tools I have were very handy for this.
  2. Thank you. I will give that a try when I get the chance.
  3. I started a print yesterday before I left work and then checked on the printer from home. I watched through the first two layers before I left, but when I got home, the glass was empty and all of the plastic was around the nozzle (or so I thought). When I got back to the printer today, this is what I found (the assembly has been unscrewed and lowered a bit so I could get a better picture): The PLA plastic had wrapped around and into the cooling fins. With all that plastic in the cooling fins (and the wiring), how do I clean it out? I hope we do not need to replace the extruder. Background:
