step/mm depend on microsteps ?

[Pseud3mys]

Hi !
I use BMG x2 extruder and the fabricant say: "E-step value 415" but when I put in config:

M92 E415.00:415.00

The feed amout is not accurate (under the real lenght). The Estep value 415 can't be wrong so what I need to change for the M92 command ?

Thank you !
Alexandre

PS: The gear ratio is 3:1 and the controller microstep is 32.

@pseud3mys that 415mm value is based on 16 steps, so for 32 steps you need 830.
But in any case, that value is only a guide and extruder calibration should be carried out https://teachingtechyt.github.io/calibration.html#esteps

@jay_s_uk okay thank you !
