It looks like estlcam doesn't produce trochoidal gcode

hi
I tried to make milling of aluminium. I read this manual and saw the video of estlcam referred on the page.
So I took this model https://www.thingiverse.com/thing:2726668 and tried to make gcode for milling 40mm diameter coin using 2mm carbide tool.

But i found that it looks like estlcam doesn’t generate spiral evolutions during milling (as trochoidaladaptive milling should do).

What I doing wrong?

3D milling is different from 2-2.5D. You are not adaptive milling you are waterline milling as you have it selected.

Am i understood right that I can achieve trochoidal miiling with estlcam only with 2D models (DXF, SVG) and can’t get it at all for 3D (STL)?
Or I just did something wrong (as example didn’t enabled and option in estlcam)?

I tried both “free machining” and “block machining” - both don’t work as I expected.
And yes, gcode generated from DXF is as I expected

Correct as far as I know you can not use trochoiial in 3D.

I see. thanks
probably it would be good to study and try cam module in fusion 360
it has adaptive milling which seems is replacement of trachoidal https://forums.autodesk.com/t5/fusion-360-computer-aided/trochoidal-milling/td-p/5860958
and it has adaptive for 3D

Yea, Christian said it’s only for 2d cuts.
