MadCam to Probotix CNC 4th Axis Post Processor
Hello All!
I am working on getting a 4th axis setup on our Probotix CNC. I have been having troubles with getting our post processor to work but it is at a point now where it seems to do everything it needs to be except I don't know how to make it run G93. Now I don't know anything really about writing post processors, coding syntax, or anything like that so I may be missing something obvious, but any help would be greatly appreciated!
Here is the post-processor I have been working on:
//MadCAM_POST_2003-12-10
*VERSION*
1.0_031210
*FILE_NAME*
Iso_G-code
*FILE_EXTENSION*
ngc
*FILE_DEST*
c:\postfiles\
*FILTER*
0.001
*OUTPUT_WIDTH*
4
*OUTPUT_DECIMALS*
5
*SCALE_X*
1
*SCALE_Y*
1
*SCALE_Z*
1
*SCALE_4*
1
*AXIS_1_CHAR*
X
*AXIS_2_CHAR*
Y
*AXIS_3_CHAR*
Z
*AXIS_4_CHAR*
A
*CUTTER_REFERENCE*
TIP
*TOOLPATH_OUTPUT*
TRANSFORM
*ANGLE_OUTPUT*
CONTINUOUS
*INVERSE_TIME_FEED_MAX*
1000000
*INVERSE_TIME_FEED_ON*
G93
*INVERSE_TIME_FEED_OFF*
G94
*RAPID_FEED*
10000
Or if there are any other workarounds let me know, thanks again!

Just use the variables for inverse time feed on and off for the first cut and last cut sections. See example below.
