X Layer shifts on long prints since upgrading to v3.5.1
Since upgrading to v3.5.1 (from 3.5.0) I keep getting X layer shifts on long (10+ hour) prints.
The only change to the printer is the firmware. Belt tension is fine.
No problems with the printer previously.
I'll downgrade to v3.5.0 to see if any better - I wasn't on that version for that long, but didn't have any issues.
I have a MMU2 which went from v1.0.2 > v1.0.3 at the same time as I installed v3.5.1, but I don't think that's responsible for this issue... these are all single colour prints that are going wrong. MMU2 has a whole load of it's own issues, but i'll keep that discussion elsewhere 😉
So far i've had 3 prints and about 1/2 roll of filament wasted due to this, as well as loads of time, NOT impressed Prusa!

Hmm, downgraded to v3.5.0 - now have X and Y shift at around 9:45 into a 10:04 print!
Maybe MMU firmware is something to do with it, will downgrade that back to v1.0.2 next...

As mentioned on another thread: https://shop.prusa3d.com/forum/assembly-and-first-prints-troubleshooting-f54/bed-preheat-error-with-v3-5-x-t26855.html , I kept getting 'BED PREHEAT ERROR' or similar at the same points on some prints, but not others.
I've downgraded to v3.4.2 and now no more of those issues, and so far no X/Y layer shifts also.
Seems to me that currently v3.5.x firmware is buggy.
