Mach3 - weird coodinate shift with inch/mm gcode change

[Neale]

Are the "units per" settings in the Mach3 config correct, or did someone use cm instead of mm there?

The mach3 units per are config to mm.
When I go under the config > select native units > there're 2 options only, inches and mm. and mine is set to mm.
Can you set it to use a cm instead of mm? If so, how to change it back to mm?

Thanks!
