Do you mean owners manuals that show you how to run the machine? If so, they suck... I've had two new Milltronics and the documentation blows, which stinks because the control is really nice once you figure it out.
Unfortunately what you really are looking for are called 'application notes', or I think they still call them that. If they ever release those things to the general public, (right now you need special permission and a password to access them,) Milltronics would have one of the best documented machines out there. Just don't hold your breath on them releasing them more than one at a time~
((You have to specifically ask for each one last I knew...))
