They both look very good.
In your WithoutCorrTable result, the highest error is ~0.54 mm. Considering how difficult it is to measure within 0.5 mm accuracy, I think that is very good. In my calibration, the highest error was ~1.3 mm. So, your calibration looks is better than mine.
Your two calibrations resulted in very similar machine parameters. I would typically use that as a gut-check. You shouldn’t get substantially different machine parameters, as long as the machine doesn’t change. So, this is a good thing.
All evidence suggests you have a very good machine calibration. I would like to see how it does with the Zipper Tree Challenge.
Further, looking at your initial measurements, they were very close to the ideal lengths. Your initial calibration was very good, too. It looks like this calibration only adjusted measured length errors by ~0.5 mm.
Thanks for doing this. I would really like to see my work positively impact others. Your successful calibration is a big step toward that.
