Hello,
I’ve been experimenting with different ways to dial in lens corrections for a Galvo fiber laser setup, and one process that works reasonably well (in terms of !/$ for time/results) is to iterate in CoreFile2 until I get the desired dimensional accuracy.
To this end, I first mark the initial 9-point test box on black card stock, scan the result at fairly high resolution (2,400DPI) on a flat bed scanner, take measurements, input those measurements and have CoreFile2 mark its standard box. I then scan that box, take more measurements, and make additional tweaks (typically, the initial test box is fairly close, but needs some bulge adjustments). This process is tedious, but results in fairly accurate results.
However, I found that even if a test box comes out near perfect at the end of the CoreFile2 process, test boxes marked with LightBurn after importing the .cor are off in scale. For example, with my 70x70mm OPEX lens, I need to scale objects to 100.876% to match CoreFile2 sizing. And with a 220x220 OPEX lens, I need to scale to 98.894%.
I’m trying to determine how to best proceed, and have a few questions:
-
Can LightBurn’s lens correction settings be made available even when CoreFile2 correction files are in use (i.e., applied after CoreFile2 corrections), such that this sort of problem can be taken care of in LightBurn?
-
If not, is information on the CoreFile2 correction file format available somewhere, such that I can make the necessary adjustments outside of LightBurn (it’s fine if this requires writing custom software)?
-
Am I better off cutting my losses with CoreFile2 and attempt manual correction via LightBurn’s settings (I’d prefer not to, since I have 6 lenses).
Thanks!
