Hello,
I was not able to try this on my lathe today but I did run it "dry" with the PC at home.
Something isn't quite right.
Watching the DRO's, every cut is tapering. And the radius..............well.
Tip Direction is 3, tool radius is .005" and offsets 0 - 0 in the tool table.
  ::)
Also, I cannot find any reference to G97, please explain.
Thanks,
RC
I checked settings, changed nothing then ran it againand got the results in the last image. Had to use camera, if I hit any key, the green tool path goes away. Pick hunter stops the run and clears the green line too.
Happy New Year,
RC

It would appear there are a few issues with comp and front/rear turrets. Brian has it on his to do list now, so it will get sorted.

Here is a non G42 version for you to try.

Thanks Graham,
See attachments for results:

I changed G3 to G2, (2nd pic), then went from Radius Format Arc to Center Format and ended up with the last pic.
With Radius Format and G2, the radius point looks to be at the X and Z intersection.
I will try to make this work for now.
Thanks again,
  RC
Interesting discovery: Turn Options.
With "Reversed Arcs in Front Post"  checked...G2 cuts CW
                                              unchecked,  G2 cuts CCW
Opposite of what I would have expected.
Anyway, the direction is OK now but it's weird in Rad. Format Arc mode..OK in Center Format.
Thanks

 Go to your Ports and Pins then to Turn Options and put a check in (or take it out) the reversed arcs box and then regen your toolpath, you should now be OK.

Hey Hood, I was editing my last post as you were responding.
I did as you said, see my edit. That gets the direction right but the actual arc is goofy when using the Radius format. It seems OK using the Center Format. 
Thanks Hood

Hi, Overloaded

If your using LCam to generate your G-code, I think, Theres a Bug in the LC Default Post.

Thanks, Chip
