/** /**
* G92: Set current position to given X Y Z E * G92: Set the Current Position to the given X Y Z E values.
*
* Behind the scenes the G92 command may modify the Current Position
* or the Position Shift depending on settings and sub-commands.
*
* Since E has no Workspace Offset, it is always set directly.
*
* Without Workspace Offsets (e.g., with NO_WORKSPACE_OFFSETS):
* G92 : Set NATIVE Current Position to the given X Y Z E.
*
* Using Workspace Offsets (default Marlin behavior):
* G92 : Modify Workspace Offsets so the reported position shows the given X Y Z E.
* G92.1 : Zero XYZ Workspace Offsets (so the reported position = the native position).
*
* With POWER_LOSS_RECOVERY:
* G92.9 : Set NATIVE Current Position to the given X Y Z E.
