DeskProto releases free CAM software for Linux.

The cutters can be found as .CTR files

Ah - I see ...
One file per cutter - not bad at all
.

For more information see the Tips page ...

Hm, the best way is change the origin in cad indeed (I use blender for that).
.

... and also in each wizard

Yes, should have used a wizard. Not bad.
I did it the manual way - and there the workpiece size is not obvious.
No matter - using a wizard works fine
.

The model that you show provides a real challenge, when you will indeed machine it I am curious to see the result !

My first model was milled using DP as CAM about 5 years ago. A friend of mine has a mill and he did me a favor
.

The challenge was - stl size of 22Mb - DP stumbled from crash to crash. We had to tweak model to get it worked out. That time, support for rotary axis was only indexed axis (if I remember well).
This is the result:
.

That's a fine looking piece.

That is a great result !
Would it be OK to post these images on our social media pages ? And if yes, what should I mention as source ?

Sure.

Source?
Don't know if I understand you right.

Source? - my brain :lol:

I model lot of curved surfaces and it was the challenge to create such surfaces in blender. Quite a lot of work, but finally I got it.
So idea and model (both models in this thread) are mine.

Milling happened on a diy-mill build of wood.
... and worth to mention: model came out of milling as is. No grinding.
Just finishing with oil.

Are you aware that Blender has a CAM version ? Never used it, but from what i could gather it is very usable.

Yes, I know.
I followed blender cam from the first day, but I don't get expected results. May be it's to complicated for me? Don't know.
Til now, I get the best CAM results with CamBam.
Its more work for the user as estlcam or Deskproto, but you can workout any kind of operation from stupid stl-files.

Let's look at next sample, a more technically sample:
.

This is an adapter to mount a jaw chuck on a rotary table.
Blender export is always a mesh, so can't use DP vector operations. But 3D-operations are not the right way to mill this part. Well, best would be to turn it on a lathe, but milling could be fine anyway (and in fact, I milled my adapters on a 3-axis mill).

The part consists of 3 levels/stages. So to do it right with DP, you have to create a part for each level and create a geometry operation "contour only" - but that fails:
.

It looks at holes that are below the part boundary and sees artefacts in stl surface ...

... and the drawback of multiple parts - you can't combine operations. Not in simulation, and I guess, gcode output does not know anything about other operations.

So let's have a look at cambam:
No matter what file u use for import, cambam works with polylines. stl / meshes don't have polylines. But cambam is that charming, that it allows you to cut the model in Z-direction, which will create a bunch of polylines (on the fly).
Just select the one you like and create an operation for that line
