Hi,
do you mean you just wish to run a Gcode program which is in inches?

If so then you don't need to change your machine at all. Just leave its native units as is.

Code g20 at the start of the file and thereafter Mach will interpret all masurements as inch units, recalculate
on the fly and run perfectly on your nominally metric machine.

One advantage of MACH4, DROs will display inch or mm based on G20 and G21 in gcode file.

Something MACH3 users are MISSING and can only wish for!
