OD calibration cannot be saved

I am trying to save the OD calibration. However, I am keep getting this error log: ValueError: could not convert string to float: ‘auto’

Traceback (most recent call last):

I did not update for the most recent version so current version is 24.3.10.

Anyone had similar issue?

Ah yea, you can’t use “ir_led_intensity=auto” with OD calibrations (we should have a better error message for this). You’ll need to change ir_led_intensity back to numeric value (a good default is 50) in the config.ini, and try again

auto was introduced recently, and it offers a simple way to pick a value for ir_led_intensity. You won’t loose much by manually choosing a value (like 50).
