I still have a bad extrusion problem. I think the extruder motor may have problems it chitters a lot. When I take out the motor, the stem is full of black grease. I clean it and next time it is full of grease again. Also the motor gets really hot.
When I print large objects, it is printing fine but about 2/3s in to the print, it stops extruding but continues to move the print head for quite some time. If I push filament at the feed tube it starts to extrude again but by that time the print is ruined. Also the final layer is very stringy and brittle. At other times it just stops and retracts the print head as if it is out of filament but there is still filament in the tubes.
I have resolved my spool issues because I watch it and the spool is rotating and filament is fed into the extruder motor.
All this is why I suspect that I have a failing extruder motor(?).
