Removing G43 from Post-Processor

[nickswimsfast]

The guy who runs our local shop says we need to remove the G43 command from the post-processor because our CNC machine setup requires us to specify tool offsets on the machine physically.

He also does not know how to do it for Solidcam. How do I go about doing that? I've done a bit of research and have found that it most likely requires manipulation of the FANUC.GPP and FANUC.MAC files. That's about all I know. Any ideas where or how I can remove the G43 command from the post processor on solidcam?

Thanks!

Edit:

I've found this section of code in Fanuc.gpp

@change_tool
if flag2 eq 0
call @home_number
endif
flag2 = 1
local logical save_blknum_gen

; {nb, 'M98 P9011'}
{nb, 'G91 G28 Z0'}
{nb, 'G90'}

; if tool_number gt 20 and tool_number lt 40
; tool_number = (tool_number - 20)
; endif
; if tool_number gt 40 and tool_number lt 60
; tool_number = (tool_number - 40)
; endif
; if tool_number gt 60 and tool_number lt 80
; tool_number = (tool_number - 60)
; endif

{nb, 'M01'}
blknum_gen = true
{nb, 'M6 T'tool_number}
blknum_gen = FALSE
if tool_type eq 0 then
{nb, '( TOOL -'tool_number, '- DRILL DIA 'tool_diameter, ' MM )'}
endif
if tool_type eq 1 then
{nb, '( TOOL -'tool_number, '- ROUGH DIA 'tool_diameter, ' MM )'}
endif
if tool_type eq 2 then
{nb, '(TOOL -'tool_number, '- MILL DIA 'tool_diameter, ' R'corner_radius,' MM )'}
endif
{nb, 'G90 G00 G40 G'(53 + home_number)}
label = first_user_proc
save_blknum_gen = blknum_gen
gcode = 43
{nb, 'G'gcode, ' H'tool_number, ' D'(tool_number+30), ' '}
blknum_gen = save_blknum_gen
xpos = xnext
ypos = ynext
zpos = znext
skipline = FALSE
call @rapid_move
tool_direction = CCW
call @start_tool
if colent eq 0
{nb, 'M8'}
endif
if colent eq 17
{nb, 'M17'}
endif
if colent eq 18
{nb, 'M18'}
endif


endp

I believe the bolded section is what I will have to change or remove. I was figuring on commenting that section out, and doing a dry run on some code to see how it fairs.

In some sample g-code's i've generated it comes up with a S764 command, with some googling I've figured out that it is a canned cycle - or group of operations. I see no other references to it in my g-code. So it doesn't appear to be a shortcut... I'm simply trying to understand the following clump of code, so as to understand how to manipulate the Fanuc.GPP file.

Here is a snippet from a G-code sample, that I'm trying to go through and interpret.

G90 G00 G40 G54
G43 H1 D31 G0 X0.369 Y-0.074 Z2. S764 M3
M8
(----------------------)
(F-CONTOUR-T1 - PROFILE)
(----------------------)
X0.369 Y-0.074 Z0.4
Z0.079

Any ideas about the S764 command - do I need it? Will it be ok to simply comment out the bolded section in Fanuc.GPP?

Thanks

add ' ; '. this is the comment. anything after this will be ignored.
this will turn off the following line.

; {nb, 'G'gcode, ' H'tool_number, ' D'(tool_number+30), ' '}


and the 'S764' code is your spindle speed.

hope this is what you need.

What you must do is decide how you want your code to look. A simple fix would be to change "gcode = 43" to "gcode = 00"; this makes the line look like this

G00 H1 D31 G0 X0.369 Y-0.074 Z2. S764 M3
