I had a failed print lastnight and a glob of pla surrounded the hotend. After heating it up and removing the glob the extruder does not release any significant material. I checked with OctoPrint and the extruder stepper does push filament without the hot end on.
After fully heating the hot end I was able to remove the nozzle.
I then pushed the previously melted PLA out of the tube and heater. It was discolored in the heater. I then tried to put the nozzle back on and pull the old PLA out of the nozzle but no success there.
Should the nozzle be left in acetone for a few days before trying again or how should this be dealt with. The nozzle appears to be blocked.
