Is there a good you tube video that shows how to use a camera to align?
Not that I know of, but basically you fit a camera and use it to align :-)
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?
Apparently it works for others, but my configs are heavily developed in
geany, by me. They came from step-config, but that wasa decade ago. Much
pyvcp stuff has been added since. There is a screen shot on my web page
in the sig.
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?
John
You can use the tool table X and Y offsets to account for the camera not
being coaxial with the spindle. Or fit one in a tool holder.
