ANYBODY, maybe that's only you RC,
Can this bad rapid move be identied in the .lcam file to delete or modify it?
Or is it to late in the process to do anything about it?

Just looking for an optional way for code modification other than doing it in MACH.

RICH,
I hope it is only me.
I tried at least 4 different STRAIGHT segment DXF's and they ALL work fine with the previous tool settings. And they all need tweaking but post good code. So I'd say those settings are fine.
I took your DXF into Autosketch9 and modified it every way I could and it still gives the error.
I think it's something to do with the arcs. I converted them to everything available and still NOGO.

RC,
 I know from other files i created that the bad rapid seems to be always there. It is creates what it creates!
So maybe just a word search of the file to get all G0 / rapid moves and you know what line numbers to pay attention to when dry running the program. If I get a chance tonight, will do a quick write up on the  parameters, which could ease pain. That would be done by showing the differentt effects on tool path via some screen shots done in some in some logical order. With that guidance at least somebody completely new would have a base to go back to or modify for a known reason.
 
Now the tools are a different story, since as you change the angle ( included angle of the tool ie; 60 deg for threading is the way i interpret it, but could be wrong ) Lazycam will generate different different tool paths. Maybe just need to make a couple of points on this and leave it go. Don't plan on writing a book.

If you get a chance. Bring one of the files into MACH. I had trouble " zooming in " on the tool path window for version later tha xx.041
of MACH. It would enlarge the piece, but not enough to see the detail of the tool paths while simulating. Pain in the neck when looking for a bad line of code.

High, Rich and RC

Rich i found usually in lcam when you run into dead end rapid like that it is a piece of trash that is put in the dxf from the cad program. then when lcam looks at the dxf it will
attach a rapid to it. zoom in on the end of the rapid, highlight that little chain and delete it. one of the things i like about lcam is the rapids feature. when you see a rapid move to nowhere,
means you will find trash at the end of it.

Thanks Bill,
I'll explore that a little.  Don't have much control over the DFX's produced by 100 different CAD programs.
So any good clues, like what you said, gives insight on how to find and deal with the output from LAZCAM.
Got anymore?
Appreciate it,
RICH

NOT NEED TO RESPOND TO THIS JUST TRYING  FIND ANSWER TO A "FOUR COMPUTER PROBLEM"
This really suck's at the present moment. Something in the tools and parameters causes the
me to get that "unrecoverable error message".  Four computers messed up at the moment,

To Lazycam future turners, no this thread is not dead yet. Just exploring the tools. Stay tuned!

Thanks, Rich, even though I'm not saying much, I'll be watching and hopefully learning-  ;)

When are you going to start writing something for the Mill portion of Lazcam?
Can't just sit back after learning it and not share that knowledge with dummies like me.

I don't use Lcam, but just my two cents worth, when I use Surfcam I know it likes the start point of a roughing/ finishing operation to be on the outside of the material, and, like almost all canned cycles, it will return to the start point at the end, which at that point you are supposed to add in the rapid away moves. Try to change the start of the cycle to the outside of your stock, maybe you have to add a line to represent the stock max diameter or something. I'm betting that this is where your potential crash is being added in at the end.
