I don't have any electronic documentation for the AMC but I an running a 2004 Onsrud with AMC controller.
Homing the machine is done during startup. Pull the e-stop and the controller will fire up. Once it's gone through it's strartup procedure it should prompt the user to datam the machine. At that point the machine should datam all axis.
Transferring NC files is done from a pc networked to the machine. I use Cimco as an editor and transfer program. Once the program is loaded into the machine it can not be edited.
Feel free to email me if you want to talk more. jason (at) mwdsgn.com
