ok good it seems the useable camera number is 1 rather then the assumed 0:
<snip>
Port 1 is working and reads images (480.0 x 640.0)
<snip>
This can be set in the INI but looks like you need to pull in an update.
Or I can show you what to fix.
after that then you need to use this in the ini.
EMBED_TAB_COMMAND = halcmd loadusr qtvcp -d -c cam_align -x {XID} -o
camnumber=1 cam_align

Thats better, at least lcnc runs, but prints this on the terminal screen:
[QTvcp.QTVCP.QT_MAKEPINS][INFO] No preference file - cannot set
preference geometry. (qt_makepins.py:160)
VIDEOIO ERROR: V4L: index 0 is not correct!

Port 2 is not working.
VIDEOIO ERROR: V4L: index 3 is not correct!
Port 3 is not working.

VIDEOIO ERROR: V4L: index 6 is not correct!

[QTvcp][INFO] Preference path: None (qtvcp:421)
So I issued a sudo reboot in case something has it running already. I'm
in the house, ssh'd into it.
so I'll restore the sshfs share, and attach the qtvcp.log. Done. I know
zip about qtvcp. Everything I done so far has been pyvcp.
Thank you Chris. Take care & stay well.
Cheers, Gene Heskett.
