Yup, changing out your extruder, even if to an identical one, changes the weight just enough to cause this. Input Shaping is indeed what you want to look for, it’ll be different depending on the printer. Some you have to adjust config files, some you can actually do in the slicer now.

I’d give OrcaSlicer a shot, it has some built-in tuning mechanisms

As long as the borders are printing you should be golden. Not something you’d want to to often of course, depending on the printer, since you might strain the hardware at the extreme edges

I’d settle for the small lag with a humidity sensor. If you’re the type to run the shower for a minute before getting in, it should kick in in that time.

Could do a presence sensor or motion sensor pointed at the shower. Haven’t played with either, and you’d have to figure out water resistance.
