No, they never explained where the Great Machine came from. How is it 'obvious' that it was not a Minbari or Human construction? It's compatible with human and minbari telepaths, after all. B4 was sent through time, remember. Who's to say that humans from the future didn't create the Great machine?

I thought that one of the Zathras' sent itself back in time using the great machine so that it could build the great machine.
