@Mark, I just saw that you posted your question here as well.
We replied to your support ticket a day after, and sent you detailed instructions on how to calibrate the camera on your big Onefinity without direct control.
Please let us know how that works out in a reply to that ticket.
I’ll then add the instructions here.
If you could send me links to the posts mentioned, I will see if they can be solved with the same instructions.
