The PTFE length is re-calculated in other places.  I think it was the Self Test.

Hi,

For accessibility reasons, I changed the position of the MMU on my printer, and I had to replace the original tube which goes from the MMU to the extruder with another one a little longer.

But this causes a problem : when loading the filament, it no longer goes to the extruder and stops before.

So I would need that the MMU pushes the filament a little longer, so that it reaches the extruder ...

Can I configure this information? I want that the filament is pushing longer or on a longer distance.

Thank you very much, for the informations that you can give me on this subject.

Excuse my rough english.

If you have a MK3 you have to calibrate the length, see here:

With the S Upgrade this is no longer absolutely necessary.
