This is on an R30-IA controller (About 2013), I noticed the missing User Frame selection in the vision process as well. We have the newer R30-IB and R30-IB+ controllers as well that both show that option.
When I took the picture of the grid it was on a spacer bringing the Z height to that of a part in the fixture.
I am also going to try and 3D print a different EOAT/Calibration Grid holder that can get me in the area I need to do an automatic grid frame set. This is how I've always calibrated cameras and never had issues.
