      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
