Can Team Ultimaker offer a reversible Firmware update process?

Posted (edited) · Can Team Ultimaker offer a reversible Firmware update process?

Good afternoon from frozen Ottawa!

 

With apologies if this has been beaten to death.

 

I've been reading the extensive threads on firmware issues.  While likely very rare, considering the numbers of units in the wild, firmware failures are so disruptive to any sort of commercial process that, like many I suppose, I'm running a number of versions behind, simply because it is stable and I don't want to rock the boat. 

 

Of course running with obsolete firmware will only work so long before the point where I can't print what Cura outputs and may not be able to directly update from the firmware I have - or that update will fail.

 

Given that these printers are increasingly marketed as professional grade,  I would like to suggest a more robust upgrade process - one that allows recovery without hours of lost time.  For example, something like a reset image written to a USB key prior to a new firmware update that allowed a back-out would reduce the hit from hours to minutes.

 

I'm sure there is a myriad of reasons why this request is impossible, but then, not so long ago, 3D printing was impossible too.  These things are all relative... 😉

If you'd like, you should be able to get a recovery image for the UM3 from your local support. The process is pretty much identical to the S-Line in terms of the recovery procedure.

 

There isn't a recovery image for the UM2+ series available. However, if you want to try a previous firmware for that model, you should be able to use an older version of Cura to update your printer since the versions are tied with the software: https://github.com/Ultimaker/Cura/tags

It is worth noting, though, that the UM2+ firmware has not been updated since around early 2018 (Version 3.3).

I hope that helps!

    It is one of the reasons why we are changing our release schedule. We are going to work with a Stable and Latest channel. People who want latest and greatest can just stay on latest (about 8 releases per year) and always get updates. People who want more stability can choose "Stable". We will only release about 3 times a year to Stable and only with features that are already  (previously) released to Latest.

    We are indeed spending more and more time on this issue. We do not only extensively test all releases with many different configurations (both hardware and firmware), but we are also looking at making the whole process more robust. On top of that, we are also looking at ways to have easier fail-modes where you can recover when something went wrong.

    Thanks for your very constructive feedback! I hope, I was able to answer some of your questions. We are working very hard on improving upgrading and although I'm not sure if a USB key is the way I will look into this.

    I'm very much interested in this too.  I would love to have the static IP function, but with all of the horror stories of people 'bricking' their machines, I held off when the prompt appeared.  I would definitely appreciate some kind of a 'safety net' in case the upgrade fails.

    There was a bug in 6.1.0 that was triggered in about 1 in 100 cases. (Technically the upgrade worked and if you had dev-mode on it was easily fixed). This bug is fixed in 6.1.1 and it should be safe to upgrade. Currently there are 500+ S5's already on 6.1.1. with out any issue.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
