You realize of course that doesn't help much... ;-)
So if I plug in a USB camera that is recognized by LinuxCNC 2.8 and above and
mount it to the Quill (for example) with offsets X=75mm, Y=78mm and then add to
my INI file [DISPLAY] section:
EMBED_TAB_NAME= cam_align
EMBED_TAB_COMMAND= qtvcp -d -c cam_align -x {XID} cam_align
That an AXIS tab will show up with the camera image?
If so how about a screen shot?
Will the screen shot show cross hairs so that lining that up on the center
point will then, with some command set X and Y to 75,78 so that a move to 0,0
now positions the spindle over that point?
