I plugged your measurements into my manual calibration calculator Onshape
and get this as the result
currently your maslow.yaml has
Maslow_brX: 2949.000000
Maslow_brY: 0.000000
Maslow_tlX: 0.000000
Maslow_tlY: 1666.000000
Maslow_trX: 2949.000000
Maslow_trY: 1666.000000
Maslow_blX: 0.000000
Maslow_blY: 0.000000
I think it’s possible that being off by ~2.5 inches ~60mm) for your tlx location could be an issue.
squaring your frame so your diagonals are closer than the current 100mm from each other (assuming no typo in the numbers you gave me) seems like a good idea
(note, I don’t know if more careful measurements would eliminate the 3mm difference between calculated and measured top left/bottom right diagonals)
If you don’t mind, I’d also like to see what happens if you put the numbers from the manual calibration into your maslow.yaml file (then power cycle the maslow) and see if that lets you move without generating errors (in theory, this replaces the calibration routine, so if it works well, you should not have to calibrate, but it would also be interesting to see what happens if you run calibration after entering these values)
This is all theory work, I don’t know if these numbers mean anything or are showing enough error to matter. This is a chance to test them against a real-world problem
