Fixed.. working like a champ now.
The blockage was actually a large chip that was interfering with the auger and wouldn't free up until I heated the unit and removed material with a knitting hook....

Continuing the cleaning cycle, but very happy now.
Can't wait to order the filter and the new motor!

Heat to 180C, remove the nozzle with gloves on. Be careful not to bend the pipe - best to remove the 4 main bolts and pull the hot end out from the rest of the unit.

The nozzle may be clogged with debris.

Insulation is ~3" long. Make sure it is rated for 300C or better.

I have a stock KS kit... except
I never did get the washers to work, so I tried to use a roll pin (which shattered), so I replaced the pin with a bit from an allen wrench.

That worked fine (I got ramen for the first 50 feet but I didn't really care because that was the cleanout cycle.
Next day (after reheating for 30 mins), the pipe clocked itself almost 80 degrees, so I took the 2 flanges apart and rotated the unit.

After figuring out the ramen problem, I ran it for ~4 hrs yesterday, producing about 15 feet of filament.... but then end seemed to be slowing down to a halt...

This morning, it clocked 80 more degrees and only extruded a blob -- motor was stalled a lot and "lurched forward" about every 1/8th revolution or so.

I've removed the nozzle.... is there something I should be looking for / do as part of a cleanout?
How do I get the ABS out of the nozzle and the tube?

PS. How long is the insulation? It seems my son ran off with it when I wasn't looking, so I need to get another piece...
