Rotation Distance calibration

General Discussion
1

Hello fellow klipper users,

I always did my flow calibration with the slicer (for example PLA = 0.85 or 85%)
I have a BMG on the printer, the rotation distance is 7.710

If I want to calibrate to 85%, is it 7.710 x 0.85 or 7.710 x 1.15?
That´s not clear to me :slight_smile:

Thanks in Advance

I read that page, but that does not answer my specific question.
The answer could be: “that what you want to try is not possible”, I could live with that and go the official way, I just want to know it :slight_smile:

But thanks for the reply.

You can do this but I would recommend against it:

  • The rotation_distance belongs to your mechanical system
  • The mechanical system should be tuned to be as accurate as possible, i.e. reflecting the reality
  • Setting filament properties, like flow (which is also temperature dependent) should be done via slicer or potentially dynamically via start gcodes

Okay, thank you.

I thought I could do it like in Marlin with the esteps value.
That explains why my tests with that value did nothing than unsuspected results.

I´ll do it in the slicer software then, as usual.

Have a nice day.
