Note the request by another commenter for a 3D surfacing video.

I'm still waiting for Mark Wieber, or any of his clique of idiots, to
discuss machining parts that need surfacing. I've seen no evidence
whatsoever that a liar like Mark Wieber, or any member of his clique
of idiots, has ever created surfacing toolpath. I have also seen no
evidence that these losers can machining anything other than simple
prismatic parts.

There is a lot more to CNC machining than just doing prismatic parts
and converting an old knee mills to Linux CNC.



Show us an example of what you call "3D surfacing".

Even the low-priced UK CamBam (primarily targeted to hobbiests) can do 3D
surfaces, roughing to approximate shape with flat end mills, and then, if
you have the time, pretty good surfacing at small stepovers and small
depth increments, using ball and bull-nosed cutters.

So, I'm not sure what you mean when you say most CAMs can't do it, unless
I don't understand what sort of 'surfacing' you're referring to.
