Help with small holes QTplasmaC

I cannot get the rules to work. It is not in the gcode either so the post is not using it.
They have always worked for me. but I'm not sure if the post has any impact on the rules.
Are you building a rule set and attaching that to your operation?

I have been through the same op. with both posts and so far I have only had the SheetCam LinuxCNC PlasmaC show any difference in the gcode.
Just for clarity is the PlasmaC revision F post redundant as that is still in SheetCam
Now I have seen this in the SheetCam post
Do the above need to be set to true ?

I didnt build it the ruleset. It was in sheetcam. I dont know if it got there when I installed QTplasmaC, did material convert or when I installed the post I am not sure. But it is there and it is not ending up in the gcode.
I got araound it temporarily by adding a tool for the holes and setting the feedrate there. I was a bit disappoionted when I saw the ruleset there and tried to use it and it didnt do anything. Maybe I am doing something wrong, something not set but it is what it is.

Some quotes from it

A suggestion here. For new users CNC plasma is a steep hill to climb especially when you combine it with using a CAM program that does not have a minimal post processor for the Plasmac branch. The PP that Rod has posted as well as the one I use are adaptations of the CommandCNC post that is "overly complex" as stated by the Sheetcam author. What is needed is a simple PP with no extra features that new users have at least some hope of using with minimal effort. Most new users just want a working plasma cutter and don't care how Linuxcnc or Sheetcam work.
I may start on a really stripped down PP if I get some time.

Now that would be cool
This post demonstrates how to use Sheetcam cutting rules

BUt in many cases, I think there is no real need to use such rules as Plasmac is so sophisticated out of the box.
