Ok, found an super easy solution!
Just use FreeCAD and everything works fine. Just like "what you click is what you get".
But if anyone whipes the dust from this topic some day, please leave an anssumption.
Im still curious, how an G-code is able to trigger an "out of bounds" inside the workspace.
Fusion coders must be one of a kind.
Anyway, thx to everyone who tryed to help! Still a super nice community!
