Correct Length of the Heat Sink PTFE Tube
I have just setup my new Prusa Mini+ and been having some filament jamming issues. I've narrowed it down to the PTFE tube in the heat sink. Seems like the tube is too short and some heat creeps up and creates a PLA plug just above the heat break. I've measured the tube that came in the heat sink at 42.84mm and the supplied spare is 43.45mm. What's the correct length for this tube?
