I have to do the «Live adjust z» every single print
I have to do the «Live adjust z» every single print. If I don't, the print won't stick. It is a bit strange, I don't know what - of even if - I changed something. The height of the nozzle is about 0.5 mm too high, I have to lower it with the «live adjust z» menu. The value showing there remains, so I started with a 0.2 mm value and the print came out well. Next time I had to give it a 0.7 mm to get the right height, and by now I reached 2.7 mm.
I did the calibration multiple times, the problem persists. What can I do?
Is your printer by any chance connected to Octiprint? If so, I recommend checking out this thread with a similar issue: https://forum.prusaprinters.org/forum/original-prusa-i3-mk2-s-user-mods-octoprint-enclosures-nozzles-.../live-z-increases-from-print-to-print-software-bug/
If that isn't the case, have you tried upgrading the firmware? If not, I would also recommend doing that. As a last resort, try doing a Factory Reset, like this article describes: https://help.prusa3d.com/en/article/factory-reset_2216
