Latest update (Fusion 2.0.20494 x86_64) crashes on lathe CAM

[rwskinner123]

In any existing lathe cam files I have, in Fusion 2.0.20494 x86_64, it will crash if you repeat a finishing outside profile.

Example:  Rough a shaft  finish profile, cut the threads, repeat finish profile to clean up threads and burrs.

During generation it will immediately crash.

The temporary solution is to edit the second/repeat finishing toolpath's "Stock To Leave" to -0.0001.

Once you do this then it will generate just fine.

This hasn't been required before and shouldn't be now.

Sorry to hear about this issue, would you be able to share a file that is crashing?

[rwskinner123]

Do you have a private link I can send it to?  I can't put it on a public forum and really don't have time to recreate from scratch.

In OP2, uncheck the Stock to Leave in the Profile Finishing Cleanup and Fusion will crash.

It's ALL my files that have a separate finishing pass that's doing it.

I've submitted dozens of bug reports under my email address.

Also, tangential extensions no longer work properly unless you do stock to leave as well.  See Finishing on OP3.

Sorry, I didn't see this notification. You can drop me an email with the file: seth DOT madore AT autodesk DOT com

I see you attached a file above, I'll take a look at it. Could you still drop me an email so I have your contact info and can look into the crash reports?

[seth.madore]

Hmm, I'm not able to get this to crash (shown after regenerating):

Which Spun Profile option are you using (set in Preferences):

I only turned off the finish multiple regions to see if it made a difference and it did not.

I just sent another error log from my email with your name in the notes.

[rwskinner123]

So if you can't reproduce it and yet I can every time, what does that mean?  I reinstalled Fusion with no different outcome.  These did not happen before this last update as I make these parts all the time and never had an issue until now.  Something changed.  What's my next move?

[rwskinner123]

Todays update didn't fix it either.

[rwskinner123]

Wow, totally ignored?  So in October, someone changed the lathe toolpath logic, and the engine now crashes or does crazy tool paths if there is no left over stock available.  It affects this which I reported and crashes  (Autodesk has dozens of crash reports) and it also affects tangential extensions that should follow the tangential line, but if there is not stock left to cut, it follows the model profile instead of the tangential surface.  This all has to do with someone's latest modifications and looking at stock left.  AI writing ya's code now?   Figure it out and fix it please!

[seth.madore]

No, not ignoring you. I've just been unable to replicate the issue, there's no crashing on my end. Obviously there's something wrong here, but it's not apparent what setting you might have that I don't. I'll chat with one of the developers today and see if we can come up with steps to replicate the issue.

Are you a member of the Insider program (do you have access to Preview Features)?

(and no, we don't use AI to write the code)

[seth.madore]

Turn this off and see if this works for you:

And it looks like we've fixed this for the upcoming major release in a few weeks.

[rwskinner123]

Still crashes if stock to leave is unchecked.

Is there a way to export my preferences in order for you to import them to duplicate the issue?

I just joined.

Are you on Mac or PC?

I think there is one method of sharing all the preferences and settings; the NGlobalOptions.xml

You won't be able to email that to me, our "malicious software detection" will likely block it. If you share it here in a ZIP file, I'll let you know when I get it so you can remove it from your thread.

You can find it here:
