tarocal Hi @tarocal ,
So it is still valid, but uses the Gen1 (version 1.xxx or lower). So when running it, if you have Gen2 installed (which is default), then you need to force-reinstall Gen1.
So @Sachin is actually making a Gen2 version of the calibration (and has been for the past month+) that he will initially release this week likely.
But in the meantime you should be able to use this, it just requires making sure that Gen1 is installed.
