Firmware update broke my Ulti 3!

Recommended Posts

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!

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.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
