Adding G90 in post processor

Hello all, I am putting together a post processor and want to add a G90 whenever a workoffset is called. I assume it is a FIL routine. Any help would be greatly appreciated.

Thanks

Josh

    This little chunk of code from my post-processor is how I handle the offset being set in the CIM file:

    CIMFIL/ ON, SET, OFSETL

    OFSTYP = POSTF ( 6, 5 )

    OFSREG = POSTF ( 7, 5 )

    IF ( OFSTYP .EQ. 1 ) THEN

    IF ( OFSREG.GE.54.AND.OFSREG.LE.59.AND.CURREG.NE.OFSREG ) THEN

    CURREG = OFSREG

    OFSCMD = TEXT/ 'G', CONVI, OFSREG, 2, '$'

    INSERT/ OFSCMD

    ENDIF

    ENDIF

    CIMFIL/ OFF

    Perhaps you could use this to add your own additional commands? The available documentation on doing this stuff is rather lacking. It's like some sort of arcane language.

    Taylor,

    In your FIL file you may try something like this:

    CIMFIL/ON,OFSETL

    DMY=POSTF(20)

    POSTN/OUT,7,90

    DMY=POSTF(21)

    DMY=POSTF(13)

    CIMFIL/OFF

    CIMFIL is the way to capture certain commands in the CL file. In this particular example OFSETL

    DMY is the return value for each function. I thas no particular use in this example.

    POSTF(20) store the current command

    POSTN/OUT,7,90 - output the G90 code

    POSTF(21) recalls the stared command and POSTF(13) execute the command.

    The G-post and FIL manuals are located in the <load-point>\<Machine-type>\gpost directory:

    ... Creo 2.0\Common Files\M110\x86e_win64\gpost\V64_GPost_CD_Manual.pdf

    ... Creo 2.0\Common Files\M110\x86e_win64\gpost\V64_FIL_CD_Manual.pdf

    Look at section 2.5.1 in the FIL manual for more details about the CIMFIL routines.

      I have been trying something similar (using INSERT instead of POSTN) but it seems to be ignored

      It looks like you are trying to output the G91 G28 Z0 and M1 before each tool change? Is this correct?
