Hi Viesturs,
I have done all that except the orientation angle. It has been
almost two years since I last played with it, so I'm having a bit
of difficulty finding all the pieces.
The camera I used is this:

Thanks Andy,
So I have to replace the drivers with the ones from Pica or Mesa. Do I
still need the encoder converter electronics?
Yes, I can see they "only" have 2.2KW, I would need ~3KW. I do not blan

This guy must have a healthy component budget and round up to the
nearest dozen when ordering ! ;-)
I suspect he has some pyro tendencies, who else would make videos of
their burn downs and then post them on the web!

I cannot reproduce the problem you describe. However, your problem may
actually be a common error that can be corrected by using the "-n" flag to
loadusr--see below.
I saved the script to the file "passthrough" in a directory on my PATH
and then ran it in 2.5 and master:

Hello!
I have a guy from university that is doing internship in my company. I gave
him a task to use opencv and write a script that would recognize a part in
webcam capture and provide a coordinate of particular feature of part
(center of a hole in part or whatever) and angle of part's orientation
Guys,
I wrote a user space python component simulating my tool changer, it works
like expected in 2.5 but it doesn't start in 2.6-pre. Actually LinuxCNC
doesn't start at all. I have tested this in SIM mode with both Axis and
Gmoccapy. In 2.5 it works fine with the Axis config.
