I have simply opened a new Topic, because I have not found my concern here yet.
My printer is relatively new, I have printed 140 hours so far, first hotent, first nozzle
My problem: a few days ago melted plastic started to squeeze out material at the top of the hot end. I disassembled the hotend and noticed that the mounting plate that fixes the extruder pipe to the heating block is slightly curved, leading to a gap where Material can escape. Where can this come from?
I cleaned the hotend and the nozzle in acetone and removed all residues, but there is still material leaking from the upper end of the hot end, which burns after a short time and creates an unpleasant smell.
