Brian,
Just tried it with version 2.00.067. Better, but the error has moved to the final line of the outer cut and has an error of +0.60mm
I don't use any cutter compensation at all.
On a Lazycam related issue. The file I sent you does a rapid plunge to -1.5 (start depth) followed by a feed to -3 before each cut. I tried this setting as if I set a start depth of 0 then Lazycam generated a pass a 0 height before doing it's first feed to -1.5. I've tried various settings and the rapid/plunge settings seems a little strange, especially for arcs. Is this use error, or something that needs optimising? I have RTFM but it's not clear what's needed here.
EDIT: Test project zip file added to show rapid/feed z moves
Thx
