PSA: Improving PTFE Coupler longevity

[Nicolinux 288]

tl;dr: Don't power off your printer right after a print finishes because the PTFE coupler won't be cooled and might degrade faster.

It occurred to me that many of us might kill some of the PTFE coupler lifetime out of habit.

When a print finishes and you happen to hear the closing bed movement (I am totally conditioned to that sound and can hear it even from very far away), you might immediately power off the printer. But the nozzle is still hot and powering off would turn off the 3rd fan too. But then the PTFE coupler has no cooling anymore. I don't think it is too critical but over time this could add up and accelerate the degradation process of the coupler.

So keep your cool when things get hot and slowly cool down when finished - you know... like IRL

Good tip, thanks @Nicolinux !

I used to turn my previous UM2 off right after the print because the rear fan was cheerping like crazy, but the um2+ has a Sunon fan which is noticeable more silent, so I'll keep it on after printing.
