Hi Art & Brian,
Getting back to LCam Turn... using ver 2.0.1, I tried creating G-code. I modified the dxf so the profile extends beyond the right and left ends so the previous artifacts would be off the finished profile. I figured I would jusr edit the G-code to take out the paths on the ends.
However, there are other errant toolpaths that cut into the profile. The toolpath takes a straight line, rather than following the arc defined by the G2/G3 command. I haven't verified the I&K values yet, but suspect the locations are the issue. Sidenote... the "k" placed in the code is lower case, while other letters are caps.
Attached are my modified dxf, and the G-code generated.
Thanks guys, Paul, Central OR
