Which is why I went to extremes to get the camera mounted such that there

The big problem with scanning photographs is distortion. Even with a
good lens it is surprising how much distortion you get.

Almost certainly, but this isn’t something I do every day, so 15 minutes is
perfectly fine.
In fact the pay-back time on

Which is usable, but slightly flawed, in that if the probe _just_
catches a corner, the retract distance means that the "i missed"
circle can miss the work.
So a slight re-think needed there.

That works a treat once the points are in the CAD.
And here is the G-code routine I used.

I have programmed a cmm, but I really don't remember anything about it.
Rapid moves are like g code, but I think the one I used had a probe command.

Anyone used a coordinate measurement machine and know how they do?
Maybe I happen to have manual but will probably not have to much time to look
into it this week.

Been so long I don't remember. I was done on the Mazak so it has been a

I can handle that, at a push. But what did you use to control the
probing process?

I think it comes down to constructing lines perp to the profile at
probed points. CMM's obviously take care of this somehow.
I've done it the hard way by drawing circles the diameter of the probe
and then doing three pt arcs to fit. Certainly there are better and
considerably more elegant ways
