Hi, jporter
LazyCam is undergoing a re-make, there are some issue's with offset's, Probally better to make a offset layer in your cad to account's for your tool offset's for now, I think.
Are you checking the G41, G42's post options, you need to use Lead-In's ON for them to work/post.
The G41, G42 are Backward's in the Post's for me anyway, view to cut, cut to view, you'll see what I mean.
Hope this Helps, Chip
