To have things the same there is really only a couple of things you need.
1. Same version of Mach
2. Same profile so that means use the same xml
3. If you have macros, Brains, Plugins in use then copy them although they may not work correctly as they may be hardware dependant.
4. Fixtures and tool tables if you use them. They are in the macro folder of the profile you are using, fixtures.dat and tools3.dat are what they are called.
4. Licence is also best put on the other computer.
BTW for Jim, you are quite free to use your licence on the other computer if you wish, the policy at Artsoft is that you can use the licence on as many computers you wish (your own obviously
) and they only ask that if you make any money from the cnc machines, you have, that you have a licence for each.
