On the older printer (MK3 from 11/2017) I realized that mesh bed leveling now takes 85 seconds vs. 51 seconds on the other one (MK3S from 01/2020). The reason is that the printhead now moves considerable slower up and down. Tried a few things (changing the distance of the PINDA to the prindbed, reflashed the latest FW (3.10.0) to no avail.

This is not what I expected. I asked PRUSA support and they said that this is OK and not a fault. It's better now but SuperPINDA is just slower on some machines. But there was no explanation (although I asked for it) why this is. It might not be a big deal. Just 34 seconds longer. Being not the most patient person in the world it is annoying. Plus: I feel that this is a downgrade to the overall performance of my printer.

The KB states that even with the SuperPINDA it should take less than a minute: https://help.prusa3d.com/en/article/mesh-bed-leveling_112163

Does anyone else experience this? What are your thoughts? Any explanations (that would be most interesting, cannot figure it out). I had a few mails going back and forth with PRUSA but they insist that this is OK. I am willing to go back to the old version. But in this case the Upgrade Kit was a wast of money...

Thanks, Alexander
