How should I do this with Estlcam?

@SupraGuy

If you do it as a carve (with Estlcam) it will make the progressive depths smaller circles so that the deeper passes match up with the outer shallow ones

…Darn, I couldn’t get Carve to cut any deeper than the calculated cutter height… Lying about the cutter diameter (taller calculated height) might be worth a try. I’m curious about how smooth the wall ends up.

Another option is the v11 Solid of Revolution G-code generator:

Having problem generating smooth gcode

Solid of Revolution (v11) generates helical paths from half a 2D cross section, e.g. your truncated cone. Getting it to machine just a pocket (or hole) requires reducing Machining diameter (I also edit the g-code to remove everything from the 2nd to last clearance plane move).
