Hi, Stitcher
LazyCam hasen't been worked on in 2.5 Years or so, It was put on hold bigger fires i guess, It was getting really close to bugs being worked out at that time, Hoping it will get past bata version at some point.
Your dxf has some extra stuff in it, Hears a tap file for you, You'll need to edit the Z moves and F speeds though.
