That heat, FWIW was coming from its illumination LED's, turned down to about half, its as cool as can be the next morning. > > With that dim a light, thermal noise > > shows, and the frame rate looks to be 3 or 4 fps.

For me in debian it was python3-pil, python3-pil.imagetk, > python3-tk. I hope they are available in wheezy. Checking now. The first 2 are not. 3.2.3 Compatible deb's? URL IOW. python3-tk now installed. > http://pastebin.com/YaCqLNzz Got it, thank you. In the previous script this new camera does 1280x1024 natively so I updated that in the two places shown as 960. That worked well except the bottom of the display was clipped off. So I need to find where I can expand the display window for that setting. > > Don't know if it is possible to integrate TKinter guis into LinuxCNC > or if another gui framework would be the better choice. AIUI, much of axis is tkinter grfx. So I expect it can be done, but I don't know how. > Ciao, > Rainer The attached .jpg looks very impressive. If I can get it to run on wheezy, I am thinking the separate display screen might not be a huge show-stopper as I believe I can setup all the HAL-MDI stuff to make it work even if its screen isn't bound to the axis gui, the gui buttons driving the usage are or can be, and that is the bottom line. I wasn't in love with the shrunken images I got by its being shrunk to fit in the backplot window of axis, so we'll see how this works once I locate the missing python stuff.
