Firmware update broke my Ulti 3!

[Clancey 0]

So I've done the latest update which the printer informed me about this afternoon, now, no matter what I try, the printer tries to print the bottom layer 3mm above the glass. This obviously isn't going to work!!

I need to fix this quickly but I can't find any options in the menu to calibrate Z. It's as if the height would be correct for nozzle 2, but I'm not using nozzle 2. I've powered on/off, calibrated the build plate etc.

Help!

Did you do a manual leveling?

Oh that sucks :(

Did you use UM3 auto bed leveling before?

The update might have deleted a stored offset to your build plate and you just need to do a manual/auto level.

Or something went wrong. There is some information on how to go back here https://ultimaker.com/en/community/51870-um3-extend-reboots?page=1&sort=#reply-192684

@SandervG Do you mind sharing the changelog for the new UM3 firmware ?

Have you updated it to the newest version or the newest stable version?

I would assume it's the newest stable version as the UM3 doesn't ask you to upgrade to a not stable version?!

Got the same message yesterday but didn't want to upgrade before knowing a bit more details about whats new/ has changed.

My colleague Matt just wrote a forum post about it.

Okey automatic updates are indeed always the stable versions. I think that you should indeed just redo the manual leveling. It probably has forgotten the saved settings.
