Create Post Processor warning dialog for a particular toolpath

iamcdn79 — Mon, 06 Nov 2023 14:58:40 GMT

There are times when I forget to set cutter comp. to LEFT in the NC Program settings when post processing for Corner Pencil toolpaths. I want to create a warning dialog to say something like cutter comp is not set for this toolpath.

I am wondering if it is possible and how.

I am thinking of creating an if statement like if the toolpath Corner pencil exists and if Cutter Comp is set to None then to pop up a warning when posting.

Hey Andre

See the attached post, I added some logic to the toolpath end, and a switch to the cutter comp off and toolpath start. This is the only way I can see this working unless you create a script to scan and capture the cutter comp setting and throw a warning.

I tried what you had in the provided post but it never popped an error message if the cutter comp was set to off. So I just created a script and it seems to work as intended *fingers crossed*

Your trap must have been missing something, or something was different in the cut file.

Glad you got it sorted.

I am trying to run the same script for Drilling toolpaths using Helical but it's not working. Do I have the correct expression for that type of toolpath or am I missing something?

I tried

and

Try

if %p(Toolpath Type)%=="DRILLING" && %p(Drilling Cycle Type)%=="HELICAL"

if (%p(Toolpath Type)%=="DRILLING" && %p(Drilling Cycle Type)%=="HELICAL")

Missed the parenthesis.

No, still doesn't work

You need to use this:

%p(Toolpath Strategy Subtype)% == "Helical"

That's not working either

Are you falling into the trap, or is it missing? Add a text block to identify if it's working.

The problem here is that your trap is only going to run if compensation is turned on. Cutter compensation isn't an easy thing to trap. This was why I built a switch into my sample posted above with the trap at the toolpath end.

I suggest that you move your warning or error trap to toolpath end. Inside cutter comp on, create a new trap to check for "Left" and have it set a user parameter "switch" from 0 to 1. Then inside your toolpath end trap, if the switch is set to 1, trip your message.

Ok, your way worked in this application but didn't work for Corner Pencil 😕

Add a text block into each trap. Where does it fail?

Re: Create Post Processor warning dialog for a particular toolpath

Sean571 — Tue, 07 Nov 2023 17:48:08 GMT

@Jonathan_Artiss19 is correct. I believe you can also put something like this in toolpath start and it should still work:

Just don't put your check inside Cutter comp on.

Is having %p(Toolpath Type)% == "DRILLING" optional or not needed?

I don't think you need to look for drilling toolpaths when you specify the subtype.

I went back to troubleshoot your original suggestion but now it works 🙃

But I like Sean's solution better to just add this to toolpath start, it's less work lol and more straightforward

Good Day,

I've have his throw up an error within the posted programs, but how do I configure the post to not post if the comp condition hasn't been met?
