Trying to get my head around these wonderful rules but getting confused, here is what I am doing.
Job is just a circle, 200mm perpendicular lead-in, Torch speed is 1600mm/min, 2mm Overburn, cut rule is set for 0mm before start set cut speed 60% and output THC off code, 0mm before end set cut speed 100% and output THC on code.
This gives me the following file...

N0180 is the THC off command but there is no speed reduction, line N0190 still sets it to 1600 which is 100%
So the THC code is coming through ok but not the speed decrease??
Am I doing something wrong or is it a bug?
What I am trying to achieve is Probe Height, THC off, Cut Circle, Overburn, Torch Off, THC on.

You said you put your thc off code "on start"
What on start does, is :
on start of cut, go X distance at % speed, then output ......code.
if distance is 0, speed wont change, but it will still output the code.
you can just create a rule for circles...smaller than...(for this job, put 250mm) feedrate...(put your60% here)
start code: will output that code at the beginning of the circle
end code: will output that code when the circle is done.

Ok, tried that and got this result...

In line N0150 we turn the torch on for the pierce, and then in line N0180 we turn off THC, I guess this will work as the machine is not moving during pierce, Mach3 will ignore any THC inputs plus there is a delay in the THC unit which does not output any signal for a pre-set time.
At least the slow-down works now, thanks.
