I haven’t used the Lightburn 9 point calibration, but I have used the EZCad2 version that runs under windows and creates a cor file.
I have duplicated the device entry I have used to setup with the markcfg7 file for my F420mm, and then loaded the cor file for my F254mm. Seems to work ok as the cor file overwrites some of the data for the lens correction and leaves the other items untouched…
