I tried to print last night but could neither extrude or retract material. Tried to heat nozzle to extrude but no effect Did not have time to try a cold pull technique and reassemble Cold Pull Link

Ran the nozzle up to 240 deg C, and let the heat soak in for a few minutes, and could then retract the material far enough (using the "Move material" menu) to pull it out and do a cold pull to clean things a bit.

The feed gear had chewed through the plastic enough to cause a point where it would stop feeding, so cut it off below that and fed in fresh plastic for it. Seems to be up and printing okay again now.
