Something weird happened today whilst printing. The filament stopped passing though the toolhead about an hour into the print and now, even whilst heating the toolhead to 220°C with the nozzle removed, I can’t pass anything (even wire) through the heater block. That is supposed to be a straight-through tube, right?
I am not sure what was in this cheap filament, but some of it went into my titanium nozzle and clogged it so badly that the clearing pin SNAPPED OFF INSIDE THE NOZZLE, so I think that is ruined.
Should I just get the toolhead back up to 220° and use brute force to push a 1.5mm hex key back up into the heater block to try and force the blockage back out the top?
