Postbuilder help regarding constant surface speed mode

[turbozee]

Currently my G-code is being output as (snippet below from actual output):
"N0070 G92 S1000
N0080 G96 S75 M03"

However, my controller requires the output: "G96 D1000 S75 M03"
1000 is the maximum speed in CSS mode and 75 is the SFM.

When I navigate to Program & Tool Path tab, Program sub tab, Tool Path, Motion, Spindle CSS

I see the option for Constant Surface Code, Maximum RPM Code, Code to Cancel SFM.

For my controller, there is no code for cancelling SFM, and the constant surface code and maximum rpm code are combined in one G code (G96)

Any help is much appreciated.

you will need to find the spindle ccs block and add "D user defined expression". then type in $mom_spindle_maximum_rpm for the expression . blocks are found in n/c data definitions.

Then probably in operation start sequence under the program and tool path tab, there should be a block somewhere the outputs "G92 S1000". just get rid of it.

If you need D before S then you will have to go to word sequencing and move it before S. If you use other D values and they are out of place then you should probably set up your own word.

Thank you. That worked.
