I just tried running the machine under mach again, and results are strange.
The Y and Z move as told, although not quite as smooth as from galil smart tools.
The X axis sounds like a jackhammer when mach tries to move it. I think this is because mach plugin is telling the galil to GA,,,A rather than GA,,,CX. not quite sure yet, will try again after work.
Cheers!
