UM2 not reading SD card

Recommended Posts

Our UM2 printer has suddenly stopped reading our SD card ( the Sandisk 4GB SDHC that came with the product!)

We have been using it without any issues for the past year, but today it simply will not read the card.

-The SD card can still be read by my laptop and Cura 15.04.5 so I know the card is not damaged.

-We have also tried resetting the UM2 to factory settings and have re-formatted the card FAT32 and have had no luck

-The UM2 reader can also pick up other SD cards so we know the machine is not damaged

Are there any troubleshooting options I can try? We will probably look into getting a new SD card or a Wi-Fi SD card, but it's quite annoying that this has happened of a sudden and I'd like to find out why this has happened so we can avoid this in the future.

I guess by the time you buy another sd card you have already recouped the costs for the time you spend fixing this ;)

Maybe you stored the card somewhere where it got damaged and the sd card reader on the laptop might be more robust.

I have lost really expensive equipment over the years due to shoddy card readers. It's quite worrying to think that something like this can render a £1000+ piece of equipment useless. I work in a design studio where it runs 24/7 so the less frequently we remove/insert the card I think the safer we will be! Is there any feasibility in a wi-fi card? will it work you think?

Just to add a note: the UM2 software is _15.04 ultimaker 2 (last updated April 2015)

is it worth trying to upgrade?

Then I'd suggest you take a look at OctoPrint. It can be installed on a Raspberry Pi and you won't need a sd card any more. Take a look at this guide:


Do you mean the firmware? Then I'd say it is safe to install the latest one that comes with Cura 15.04.5.

Did you ever find a solution to this issue? I tried another SD card but it didn't work either. I have thought about upgrading the firmware but if I can't read the card not sure about my options at this point. Need look into other methods. If you or someone else was able to resolve please let me know!

Thanks Scott

    • "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.
