Okay, I removed the threaded filament feed tube from the heater block, dipped it in boiling water for 10 seconds and the filament came right out. The PTFE tube appears to be intact and filament slides through it perfectly. So, nothing damaged apparently. No idea why the heater could not free it the same way. Bobby BobK - Prusa i3 and variants
Since I cannot even pull it out, I don't see how a new nozzle would help. It would be the entire hot end that I would have to replace. I hope I don't have to do that every time I change filament Bobby BobK - Prusa i3 and variants
Very new to printing with Prusa I3. I tried to change filaments, and my PLA filament became stuck. I cannot push or pull it, nor can the extruder. Tried heating all the way up to 260C and this did not help. Help! Bobby BobK - Prusa i3 and variants
