Hello there Ultimaker friends,

 

Getting some intermittent trouble with my UM3 after updating to the latest firmware (5.2.18.20210820 stable), including:

- OLED screen breaking on/near print completion (see image)
- Wi-Fi dropping randomly

 

Things I have tried:

- Factory reset
- Flashing recovery image and reupdating

 

The issue persists, so I believe it's some sort of firmware bug. Since it the UM3 firmware isn't actively developed anymore and it's impossible to downgrade to the previous version, can anyone help out? @CarloK?

 

Logs/images attached.

 

Also, well done for sneaking this in:

@mahtt Congartulations on finding the Ultibot. 😉

Sorry to hear about your display problems, this was exactly one of the things we tried to fix in this release so I'm very surprised to see it popping up when it didn't happen before. Also weird that you mention a downgrade is impossible. We tried downgrading here internally several times and I left 5.2.16 for this purpose on the Testing channel.

 

The only thing that comes to mind, is that you updated your printer just after our initial release. There was a short time frame where a wrong download image was hosted. Could you try to download 5.2.18 again from https://support.ultimaker.com/hc/en-us/articles/360011587199

Copy this to a usb stick and re-install. I'm eager to hear your test results.

    I've updated with the latest build via USB and so far so good - the OLED hasn't corrupted yet. I'll keep an eye on it.

    Strange how the update via the network still led to a bad screen though, as I did the process yesterday via the machine after flashing a recovery image, so it seems like it would have been long after 'correct' image was placed on the update channel.

    Ah, actually I didn't notice that. Good to know it's there if I need it.

     

    Cheers!

    Yes, weird indeed. The 'wrong' image can't be your problem here. What version did your Recovery image have?

    Never mind, using 'https' instead of 'http' seems to resolve it.

    Unfortunately @CarloK my screen just corrupted again.

     

    Since the last message I have used the recovery image above and also played around with multi-point bed levelling, but this is now disabled on my machine.

     

    The corrupted screen seems less frequent now but the cause is still unclear. It seems to occur towards the end of a print job. I aborted a job remotely through the DF and found it corrupted when I returned to the machine.

    Logs attached, I'll keep monitoring it.
