Les commented recently on path rules in another forum, perhaps his comments apply to your situation also, or at least in part.

Version 28.7 Inspired by @ROTM from this recent post and drill pecking tutorial, I adjusted my .scpost accordingly. Thanks @ROTM. https://forum.sheetcam.com/viewtopic.php?p=31626#p31626 Note though that I'm choosing for now to not change the tool or amps for plasma drilling and pecking operations. I...

so I simply added this simple template example of OnDrill() and it produced gcode, however I don't know the gcode stmts for this controller so I don't know if its correct. But you can tweak the OnDrill() function if need be at this point. function OnDrill() OnRapid() OnPenDown() endZ = drillZ OnMove...

it appears the problem is that there is no OnDrill() function defined in the .scpost.
I'll put a basic version of OnDrill() in and see how it goes.

btw- I like the coded model to define external vars and custom options, well done. I saw one a few ago similar, or may have been the same one.

you also have the first "shape" at 0,0 it appears. I seem to recall some obscure SC bug a few months ago when the first start point is at 0,0, and that was about the time I was customizing my OnDrill() function and testing it. Try moving the part off 0,0 origin before we go to far down thi...

could be any number of things. does your .scpost have OnDrill() customized ? pierce delay is 0. Does the torch fire at all ? pierce hight - cut height is only 0.020", that's going to be quick. best if you post your .job file and .scpost file, and the .nc file you're getting. Easier to diagnose ...

fyi...
perhaps you've seen this, I just stumbled onto it...

version 28.6 28.3 change double Torch Probe Cycle to single, 28.4 added feature to bypass Torch Probe Cycle if LdcTorchProbeTravel = 0. 28.5 changed OnDrill() pecking parameters. LdcDrillPdPct -- Plasma Drill peck tuning, % of pierceDelay, 0-150 LdcDrillChPct -- Plasma Drill peck tuning, % of cutHei...

You have to adjust the floating torch distance which actuates the probe switch. I arbitrarily set it at 10mm. Given you report that the torch is cutting 0.25" too hight, your value is going to be 10 - 6.34 = 3.66mm Edit the .scpost and replace this function with this corrected code. I also made...

I’m not sure what indication the simulator would give. Have you looked at the Gcode file to see if the M8 and M9 statements appear?

Try the attached, it produces the following gcode, PH being 3.2mm in the tool, XY being the pierce location.
See the function DoTorchProbeCycle() to make adjustments.

you're welcome. please report back how the misting approach goes in terms of the plasma cutting process. I run with a water table. Some use a down draft table. I have not researched this extensively, but what I have read and experienced is that the purpose of the water or down draft is to capture or...

welcome to sheetcam. how do i turn on and off the coolant m08 and m09 with sheetcam whenever the plasma turns on and off at least two independent ways to do this... 1) associate a Path Rule set with your Tools or Operations. This is a multi-step process to setup but you'll find the process handy for...

I'm not aware of a "free version" of sheetcam. The real sheetcam product downloaded from sheetcam.com clearly states "this download is limited to approximately 180 lines of generated code. You need to purchase a license to remove this limit. "

you'll have to be more specific, best if you post your .job file and cite which version of sheetcam you are using.
