When you did the lens calibration, was the pattern filling roughly 1/3rd of the view horizontally & vertically, as shown in the tips here?
The most common thing people do is lay the pattern card on the bed and run it from there, but the lens calibration part has nothing to do with the laser, just the camera and that card.
Using the fisheye option should give you slightly more usable image, because it doesn’t discard the stuff that’s clipped because of the warping.
