Endstop adjustment for multi motor axis - firmware wishlist

[jay_s_uk]

With RRF3, its possible to home an axis using multiple motors and endstops without having to split the axis during homing.
However, if any adjustment of the position of the gantry is required (due to misalignment of endstops, no way of repositioning them etc), the old method of splitting the axis during homing must be used.
My request is for an endstop offset that could be applied to just one axis during the homing procedure, removing the need to split the axis.

I think there is a gcode in marlin for this?

@phaedrux you are correct https://marlinfw.org/docs/gcode/M666-dual.html

@jay_s_uk @Phaedrux RRF has that too, but only for delta kinematics. https://docs.duet3d.com/User_manual/Reference/Gcodes/M666

I think it would be a useful addition for other kinematics.

@droftarts yes, I am aware we have it for deltas.
I think an expansion to match Marlin would be a good addition
