Nozzle and Print Bed Keep Heating After Filament Unload or Filament Load

As my new Prusa Mini+ is an addition to my first filament printer (UM3) I am wondering why unloading or loading filament is

  • accompanied by heating the print bed
  • followed by steadily heating the nozzle AND print bed, after filament has been loaded or unloaded

I cannot see the purpose (and the UM3 only heats the nozzle for the sole process of filament loading)

Well, you're not alone wondering. I can see the point of keeping the nozzle at operating temperature because more often than not you may load another filament to continue. (plus, it will turn heating off after a while anyway). But heating the bed feels like a waste of energy.

I had been waiting for about 20 minutes, but I lost patience then and pressed the reset button ...

Ok, your thought about color change isn't so farfetched, but even then the firmware should know whether a print is pending or not.

I've been wondering for years 🤥 Prusa uses the Mini in a print farm. So they probably profit themselves but for normal users this is only waisting energy.
