Hi,
I had to redo the vision master recovery for one of our Fanuc robots and even though the whole setup is same as before ( our camera is fixed, the lights are mounted at same angle, the distance is 400mm from the camera and the laser lights perfectly align with the x and y axis), I am getting the maximum measurement error in the range 0.9-13 in different iterations I have tried. Not sure what i am doing wrong here as the first time I did the vision master recovery everything went very smooth.
Attached are a few pictures.
Also I found out in the manual it says "If the max measurement error is considerably larger than 0.5mm, possible causes are that the lens or camera is not secured (in our case it's fixed), the lens is out of focus (it shouldn't be as it's giving me the right image on the tp) and that the calibration grid is not secured (it is perfectly secured).
Does anyone have any other suggestions as to what else I can try? So far I have tried increasing/decreasing the 400mm distance (little by little), changing the exposure time, illumination, but nothing is helping. My evaluation index for reference is 4.2
Thank you.
