Hallo Fern,

The new spiral tool paths are not so heavy for the milling tools, as the load is more constant. Please find attached my parametric spiral ngc code in the most recent version. The realized path is shown on the screenshot, and that looks more uniform than yours.

I am thinking about a different approach for complicated features - external python scripts that generate g-code based on input arguments. As we did with text engraving feature. It is a lot easier to do heavy math with external programs and you would still use NativeCam as user frontend to pass arguments to external programs.

I am looking at this repo github.com/aewallin , but cant find the time to dive in. It should be quite easy to do pocketing generators for simple shapes with true elipsed toolpath using opencamlib.

I am currently working on a G71 lathe cycles that will work like your polyline for mill. Complete profile is sent from NativeCam as argument to python script and it returns plain G0-G1-G2-G3 moves. This also has benefits because you can use run-from-line to start somewhere in the middle of roughing.

I agree

Yes this is easy

I will take a look at this code but I am also short on time until end of October

Depending on the license
