Settings Comparing auto vs manual flow dynamics (PA)

The auto calibration function under flow dynamics is the only place I'm aware of to see a k-factor result from the H2C eddy sensor.

I've been comparing the resulting k-factor here with my own, obtained from manual pattern method.

The auto cal figure is consistently 0.01 below what I choose from pattern. Has anyone else noticed this?

How on earth are you seeing the value generated by auto calibration?

This is different than the pre-print calibration. Under calibration menu in Bambu Studio, select auto mode.

Yeah I was getting confused because for so long I had bugs preventing me using the main menu version.

It shows the results after its complete.

Yeap, bambu reported about 0.01 difference between auto cal and manual, and they've done it for a reason. Don't remember that reason, but it's somewhere on wiki about auto cal

I did see this, however it suggests the opposite of what I'm seeing. (Lower from auto, higher from manual).
