Check if you are using “world coordinates” in the left lower corner of your Rhino window.
are you working with different CPlanes in various views? What Norbert is suggesting still should work the fastest, maybe try typing w0 instead of 0, what should override any CPlane coords and put it to World 0,0,0
you can use SynchronizeCPlanes to update the others, but if you are confused whether the cplanes have been changed, the command 4View (hit it twice in a row) should reset them all. the above mentioned method then should definitely set the wished point to world origin.
also you can use the gumball to drag then while dragging hit 0 and space or enter and it then beams it to world origin. to permanently have the gumbal in a group of object stay at where you want it you might have to use blocks. groups dont keep the gumball unfortunately… (at least on mac)
type w0 instead of just 0
Here is a script if you want it…

I don’t know if this was ever answered but in Rhino7 you can use the command CPlane and click to the location you want to move the origin or 0,0,0 coordinate.
maybe you should read a few of the comments then? i think every single possible option was given as far as i can remember.
That original question was about moving geometry to the World origin, not setting the CPlane origin. Rhino allows the user to change the visible coordinate system while the geometry and calculations remain in the original World coordinate system.
