BTW that is an old version of the Addons so might be worth upgrading.

Yup, verified.
The older V. is a bit goofy and needs the run-around posted earlier to view the path correctly.
Upping to 2.86 fixes it.
Here is the latest V.  http://www.machsupport.com/forum/index.php/topic,18321.msg126231.html#msg126231

Thank you!
I tried doing POST CODE and VERIFY TOOLPATH, then it works fine!
Maybe, is it a problem related to only preview?

By the way,
I found difference on Groove function.
There are two screenshots, one is "Cut Circle" with Groove on/off, and another is "Cut Rectangle". It seems Groove option is not functioning at "Cut rectangle".

Oh,,,
I upgraded the addon to 2.86, and now it works perfectly!
I decided to purchase this fine addon. thank you!
