Help with small holes QTplasmaC

I have seen similar behaviour also. I have rules in and when selected to slow the feedrate with radius smaller than x, it doesnt do it.
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?

------ Configuration options ------

-- Set this to true if you have the multi-tool option enabled in PlasmaC.
-- If not set it to false
multiTool = false

-- Set this to true if you are using a material file.
-- See http://linuxcnc.org/docs/devel/html/plasma/plasmac-user-guide.html#material-file
-- Set it to false otherwise

materialFile = false

-- Set this to true if you want SheetCam to control the feed rate.
-- Set it to false otherwise
-- NOTE if you use rules to change the feed rate, these changes will affect the
-- feed rate even if useFeed is false

useFeed = true


---- End of configuration options ------

Guys

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.

I might add that if I could also get Linuxcnc to calculate the arc radius, there would be no need to ever use sheetcam code snippets....
Now that would be cool
