I’ve noticed that while the hot-end is hot (215 C), the thermistor can freely slides out, indicating that the contact is not very tight (I have not touche the M3 screw since receiving the extruder as part of my Prusa i3 MK2S).
Given the warning above I assume I should not try to tighten the thermistor while the hotend is hot since it will deform it when it cools down?
(Indeed I don’t have any problems with the current setupas as PLA melts at 205C/215C as reported by the thermistor, indicating it’s accurate even though it is not tight when hot).
