here are the files. As i said its just a modified version of the ones found in wiki.linuxcnc.org/cgi-bin/wiki.pl?Axis_Embed_Video
what I did and how it works:

changed the way camon and cam off works so that it just does a relative move, with an offset which has been saved previously (meant to be used with a fixed camera)
MARK-CO: after performing a mark with the actual tool on the workpeice, this button is pressed to save current coordinates
CALIB-CO: with the camera centred on the above mark, pressing this will save the offsett between the tool and the camera
CAM checkbox: toggling this moves the axis so that the camera is in the place of the tool, or vice versa (performs a positive/negative g90 g0 with the saved offset)
SAVE XYZ wroks the same as before just added a debug so it shows the saved coord.

how to perform rotational offset:
load nc file and install workpeice. make sure there are no rotational offsets are present in the current coordinate system (G10 L2 P0 R0)
move to first reference point (lower leftish) on the backplot and press SAVE XYZ
move to the same point on the actual workpeice with camera and SAVE XYZ
move to the second reference point (upper rightish) on the backplot and SAVE XYZ
move to the same point on the actual workpeice with camera and SAVE XYZ
press ROTATE and then reload the program (CTRL+R) << cant find a way to do this automatically in the subroutine

performing X-Y offset
move to a reference point on the backplot and SAVE XYZ (point A)
move to the same reference point with the camera on the actual workpeice.
uncheck the CAM checkbox so that the tool will move in-place of the camera
press OFFSET and reload the program

i've known glade and oword routines for like 2days now so comments on any mistakes or suggesstions would be greatly appreciated.

Adding a webcam to my plasma machine is something I definitely want to do, but it seems the instructions for getting it set up apply to EMC2 and not Linuxcnc. If I try and get things working for me, I seem to be constantly running into trouble. Is there any instructions I can use to get my table set up with a webcam and keep my current configuration of linuxcnc?

Hi

I think the root of the problem is the .deb dependencies of the packages, requiring now deprecated files since the switch to linuxcnc.
Looks like the files in pshas /pool dir of his repository were last updated in Nov 2010

If you are comfortable with it, you can either use dpkg --force-depends options or simply download the packages and manually install the elements from them.

A .deb file in common with many others (.ipk etc) is simply a glorified .tar.gz. With a decent file manager like mc you can open it and transfer what you want from it to your system.

If that goes a bit beyond your comfort zone, you might have to wait for psha to update the packages.
He is a very busy chap in the development of Linuxcnc.

camview itself is unproblematic, but you can see when it gets to camview-emc, there is a circular dependency upon emc2 rather than linuxcnc.

As per previous, you can get around it if you know what you are doing.
Alternately if you haven't upgraded to 2.5 or installed from the latest LiveCD, you can probably still use the packages as per the instructions.

regards

I've updated packages agains current linuxcnc2.5 repository but have not tested them.
Only changed part is emc2-fake package and emc-camunits.

upd
Sorry for such long delay
