Esteps is not an accurate setting as it is hard to measure precisely and like for extrusion multiplier it depends on the filament.

It might only be necessary to calibrate estep if you use several printers. In this case make sure to calibrate estep with the same filament from a quality manufacturer.

Definitely a good idea, thanks for sharing it!

Prusa changed several times the hardware coming with the extruder and the latest version does not have M3x25 screws anymore. Please refer to our BOM for all the necessary hardware.

We need to keep some margin for this one unfortunately.

This one is a bit more difficult as there is the bridging, I need to keep some margin for not perfectly calibrated printers.

I have added this to the task list, thank you.

Thanks, fixed!

Thanks, updated!

Thank you! David Ogles, Nathan Denkin and Matt Harrison gave me massive help to build this guide too.
