ALARM 3 eveytime after camera install for an image

Never problem. I just installed the 120 degree camera and all calibrated good…(Ithink)
While burning a small image approx 2 inch square. Update overlay, open image and move to my wood work piece.
First 3 tries I get Alarm 3 about half way through the burn.
Close program and reboot PC, try again…reset again about 1/10 way into the burn.
USBCOM port speed is at 9600, reset it tp 115000, same problem, so I put COM port back to 9600 and got the last result.

Before camera, never experienced this, maybe not related either.
Now not sure hat to do.

I believe now it is a bad control board. Changed to a different board and no more long stationary 5 second burn on connect, disconnect and fail Alarm 3. Keeping an eye on it to make sure the new (better) control board.
