After I calibrated my camera, I found the system to be pleasantly accurate. I used it successfully for a while without issue.
Now that I haven’t used my laser in a month, now I discover that the location is off quite a bit. I didn’t make any changes to the camera or software (other than just having updated to 1.2.04)
I guess your camera has moved a few millimeters, that will be enough to make the camera setting no longer fit. If you have mounted your camera in the lid, it could be that it does not open 100% the same every time.
