Error I don't undertsand sh**t about
I get an error message immediately after I load an .stl in the slicer , stating: Error G92 E0 was found before_layer_gcode. Which is incompatible with absolute extruder addressing.
I don't understand anything about this message. Where is stuff going wrong? Please help!!!

What configuration profiles are you using and where did you get them from ?
The problem area is located in the Expert sections. Most modern 3D printer firmware can run commands that use either Absolute positioning or Relative positioning. So you can use either configuration in the Prusa Slicer settings. However one thing you have to be aware of is that depending on what you have selected then some gcode commands shouldn't be used.
The specific one you list G92 E0 is basically saying reset the E value before every layer change. The E value is the total for the amount of plastic extruded. It is fine to use that command if the Extruder has been set to use Relative extrusion in the Printer Settings.
However if your extruder is configured for Absolute values then you need to keep a total running value from start to end of your print. Resetting the count in the middle of the print basically sc**ws things up. So Prusa Slicer is warning you about the settings mismatch.
You need to either change the extruder to use Relative addressing (which may be done in a couple of places, ie the Printer Settings general or even your start gcode OR you need to delete/disable that gcode command in the before layer change field.
Basically that printer profile you are using is crap, which is why I was asking where you got it from.

@ Neophyl
Many thnx for the detailed explanation.
I have a custom build, which is , as a matter of facts, almost 13 years old. It is based on the original Prusa I3 with a few tweaks. As a mechanical engineer I was horrified with some of the engineering failures of mister Prusa. But in the end he was then a economy student and not an engineer.
But I solved it already. I just just chose a complete other configuration profile. This also solved my problem with the z-spindles where the steppers started to humm in a very loud and protesting manner, clearly not being able to accelerate or come to the requested speed.
