I couldn't work out how to post a picture or I would have done so.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Can you click Save Project, and send me the .jnt file.
Sounds like JointCAM didn't like some of the data that you input. I need to know what that data was.

I also received an error message when trying to output code after upgrading to current version. Tried a clean install (backed up my user settings first) and still got the error so I uninstalled again and went back to original version which is working fine.

Are you saying the current version is giving the error? Can you reproduce it? If you can, can you send me the project file?

I haven't heard back from Bob yet, but I need to be able to reproduce it.
I've been creating g-code regularaly for over a year and have never seen that error.

What OS are you using?

I sent you an email with my files and details.

I'm pretty sure I have this narrowed down to a depth per pass setting of zero for roughing passes.

I should have a new version Sunday night that fixes it.

I spoke too soon.
The issue is the new Scale Feedrate feature.

I didn't want to over-write the settings, so it may be turned on with no scale factor set.
If you see this crash, just go into settings, and make sure there's a non-zero value in the Scale Factor, or the Scale Feedrate is not checked. Then just Save the settings and the crashing should stop.

The depth per pass I mentioned in my previous post is still a possible issue, and I'll fix both of these tomorrow.
