Z movement on Unload Filament?

Hi!

I've been noticing this weird behavior through several firmware updates, and it's still happening in 3.12.2.

Basically, when I do certain things from the front panel menus "Unload Filament" being a good example, for some reason the Z-axis moves upward, maybe as much as 10-20mm. before unloading.

Is this intended behavior or is my (completely stock MK3) just weird this way?

yes this is intended it is so the nozzle isn't to close to te build plate and will form a blob destroying the nozzle

I usually don't unload (or load) filament unless the Z is at least half-way up, so that didn't occur to me. Seems like a sane precaution though.

Yeah me too but they’re some people that dumb af like look at some reviews on Prusa products like the powder coat pei people rate a 1 because they used pla and it didn’t stick and they probably didn’t use a new live adjust z or the amount of people that go to the forums with my print is not sticking and having they’re z offset at -0.040 so Prusa uses safety precautions in the most ways possible
