this post processor defaults to Metric 

see comments in mach3.gpp for changes needed to convert to Imperial 
change needed is :
change G21 to G20 
change Z10 TO Z1 for 1 inch above z , this can be any value you like 

@start_program

    call @gen_nb
; change the line below to G20 for Imperial Initialisation 
    {'G0 G40 G49 G80 G21 (Metric Initialisation)'}
    call @gen_nb
; safe z setting change to suit 
    {'G0 G53 Z10 (Return to origin machine & 10 mm above Z Zero)'}
    call @gen_nb
    {'G0 G53 X0 Y0'}

endp

hope this helps 
any problems let me know and we can update this postprocessor
