Trouble CNC fill multiple shapes

Hello all, total newbie to this world
I’m having some trouble with the CNC on the snapmaker when trying to cut out a Fill, when there are multiple shapes. One shpe inside another shape. I want to cut out exterior shape and leave interior shape.
But even playing around with multiple toolpaths for both images, it still wants to fill the whole interior area, ignoring the second shape.
I’ve tried all sorts of toolpath combos, tried different file formats.
Any and all suggestions welcome
Cheers, Tom

If you’re trying to use Luban it kind of sucks for cnc.
You really should be using Fusion 360.

To make it work with Luban you can either create a 3d object in something like Tinkercad and save as an stl.
Or you can treat it as a relief and save as a png. Everything black will be cut. Everything white uncut. (or vice versa if you invert) (grays will be in-between depending on their shade) Set depth of cut in Luban.

Yep as sdj544 says, Luban is going to give you issues if you are trying to create selective toolpaths for various features of the model.
