Prusa mini extruder jams in the middle of print with clicking noise.
I had exactly this after my first month of great printing. After raising the hot end, mentioned many times in this forum, and replacing the PTFE tube in the hot end with the spare, after the original shrank, reliable printing was restored.
I've tried all of them. It still doesn't print.
I'm getting a return label for a refund. They don't refund a shipping cost which was over $100. I feel horrible.
