By playing with glade-gtk2, I have managed to arrive at something that works, part of the time. But it goes away too, leaving a blank, white, camera image window. It seems to be related to expanding the axis window, which is basically about 1/4 screen at LinuxCNC's launch defaults. The cameras basic image is 640x480, and I can make it go away quickly by attempting to expand its viewing window to more than 480 high. Frame is about 15 to 17 fps, which is usable. Last time I had it working well about 2 years ago, the frame rate was only about 2fps, so you moved the machine, then waited several seconds for the image movement on screen to be completed. Essentially worthless then, but now its plenty fast enough to be helpfull. More computer, the D525MW boards do not have the horsepower. Set for a window size less than that, it can watch the machine home itself, but clicking the cam/tool position toggle will watch it move to that offset, but moving the machine to start recording the constants used in the auto-align functions will always make the camera die while the machine is in motion but at some random point in the procedure. Cableing is fine, I can slide the camera off its mount and wave it all around without a glitch. This is the only error logged on the starting terminal when the camera tab goes blank: /usr/bin/gladevcp:295: Warning: g_object_ref: assertion `object->ref_count > 0' failed gtk.main() Does this tell anyone something about how to fix it so it doesn't go blank? It sure doesn't here, don't know enough about glade, either version. No help available in either glade-gtk2, it claims my GladeUI-Message: The DevHelp installed on your system is too old, devhelp feature will be disabled. DevHelp is wheezy latest, 3.4.1-1.
