Hi Farv,
Welcome.
If your machine is set-up in Inch units and the Gcode file you are using has been compiled in Millimetre units then everything will be small unless...
Use Notepad to edit your Gcode file to add G21 (on a new line) at the start of the Gcode listing. This tells Mach3 that the file is in mm units and it will then scale the axis movements to match your machine units setup (hopefully).
Tweakie.
