If I can keep the original Grimlock on the battlefield, what happens then, if I use him to collect another set of Wave 2 Dinobots and play another Enigma? Does the first Volcanicus get Bold 2? Do I assemble a second Volcanicus?

Yes, you can assemble multiple versions of Volcanicus. In the extraordinarily unlikely event that you are able to assemble multiple iterations of Volcanicus on the battlefield before your opponent either defeats you or flips the table over, they would each get bold 2.
