Another tab for WebCam

that is probably true for a M$ windows.
in linux you can define the window under the mouse pointer to have focus, without bringin it to front.
It's just been disabled by default in the last couple of years to ease the transition for folks acustomed to the "windows" way.

I'm too new in linux and doesn't know how to do that. I can't find solution for:
What to do to start EMC in maximized window...
What to do to have camera window always on top (unles is minimized)


How to make button in pyVCP to execute some Gcode or M1xx code

Alex,

I am not trying to defend that the camera is a bad idea. I think it's a good idea to have some form of camera function within axis rather then separate windows floating around. I personally don't mind the floating windows (I have a mac, every window is floating, currently 30 windows open)

When it comes to accuracy I think that a probe can be potentially more accurate, specially that afterward you don't have to change your bit anymore, a probe doesn't care about parallax or ultra small parts, but this is not the discussion abouth what's best.

If you setup a camera permanently you always will have some form of parallax going on. If you put the camera in your spindle then you have to change that later again for a real bit AND then do high adjustment again.

I think if we want to have some for of camera IN axis then this should also add some function like camera selection, color channel selection light that can be controller by axis using a PWM to setup the amouth of light added to the workpiece.

May be when I have some time I can add that function and supply a patch for it, unless you want to do that...

Hello...
Select windows when the mouse moves over them works for jogging. But when I like to execute homing, touch off or others the camera window goes into back. Not realy what I want. And other windows comes up where not nedd to be. (date for example)

For starting maximized I think there should be some other way. I don't like to install new application just po push maximize button. There are probabli some vay to do inside source with few lines of code. Probably can be configured in *.ini too. (eg START_MAXIMIZED=1).

Today I just discover that I don't need to recompile EMC just for changing AXIS. So seems that I go to learn python and make some mess inside AXIS

Wow, great work eslavko!
Looks like something I could really use. Can you give some more details on how to implement this?

Thanks,
Greg

Nothing special here.

Just download gqcam from web to check if work with you cam. (you can install with package manager in ubuntu).
If that work's then you make next step.
Uninstal gqcam...
Get source from the web (sourceforge)
Compile itself.
Test if works.
That's all.

Of course if you can live with all that sliders under camera window.
If you don't like it then ask me for modified source (or modify yourself).
As I "cripled source" I don't want to upload in the form as is.
I' plan to port that into python and make as a module for the axis. (As I want to ba all in one window).

Don't expect to be done fast!. I didn't write even "hello world" in the python! (I write that in C and not much more )
... and tcl is needed too.

I just wander why so much language is used to make EMC2 ussable. C, CC, GTK/TK, Python, probably some more and just not discover that.

Slavko-
I have finally gotten a webcam (logitech c260) which works well with Cheese but with gqcam I only get a solid green image. So it looks as though I will have to try and modify the Cheese source to get the crosshair overlay. Could you share your modified source for gqcam so I can get an idea of how to do this?

Thanks,
Greg

I have some success in embeding video tab into axis. Everything is described in wiki

wiki.linuxcnc.org/emcinfo.pl?Axis_Embed_Video

Thanks. I never would have found that in the Wiki without your help.
