How to set steps per e

[tomnagel 80]

In the preferences window of Cura, I can set the steps per e. since command for extrusion of 100mm leads to 105mm filament, I want to adapt that figure.

But how does that figure end up in the UM? What if I slice with Kisslicer, and print with printrun? I checked this during printing with M501 (by heart), and I saw the default value for steps per e.

Another question: I wanted to do the calibration of steps per e, and started the procedure for the first time checks of UM, as I believe it was in there. But is was not, it is able to flash the firmware (skipped that) and it tested all end switches. But no steps per e procedure.

I did it with manual commands in the printrun terminal (G1 E100), but that is kind of a difficult procedure (also needed to override cold extrusion).

Where is the steps per e procedure?
