Hi there, I have the original Mini 1, everything is how it was purchased. It’s been years since I’ve just recently started using the printer for serious work. While printing today, it suddenly stop extruding. I found out that part of the hot end stopped working. Please excuse my ignorance about the printer as I’ve only successfully done the printing part but not too familiar with repairing or understanding how each part of the printer works.
The filaments seems to be stuck at the upper portion of the hot nozzle, shown in the picture. I tried pushing the filament through and retracting but it’s completely stuck. Is that part of the hot end suppose to get hot too? I cranked up the temperature but it doesn’t seem to help with pushing or retracting the filament. What is the maximum temperature that I can set the nozzle to?
What steps do I need to go through to fix this? What is that part of the nozzle called?
