ulticontroller see sdcard empty

Posted · ulticontroller see sdcard empty


I just finished my first print with the UM original and it is really nice !

But I had to launch the print from my imac because the ulticontroller don't see the files I added to the sdcard.

I tried to format the card twice (first from my mac and another time from windows XP) as FAT32 but still nothing.

The ulticontroller notice that the sdcard is inserted but when entering it there is only a "main" option that get me back to the previous menu.

Any idea on what can be wrong ?

    Sometimes it helps the small write-protect switch of the SD card back and forth to move.

    I was able to format my SD card without any problems, but my UM2 did not show content.

    After that there were no more problems.

    Hi guys, I'm having the exact same problem as Jonathan, but I've tried formatting and saving the files again onto the SD card. I've tried both AMF and STL files. I've tried inserting the SD card both with write protect on and off; but it still regards my SD card as being empty. Just an option to go back to the main menu.

    This is quite poor. As well; my ulticontroller screen keeps on glitching randomly, and you cannot read what's written there unless you unplug the USB cable and plug it back in. I have check the connection to the circuit board and it's solid. It glitches even without being touched.

    Any help you guys can give would be much appreciated.

    Hm, that does not sound so good, here is a small ToDo list for you :

    - SD-card < = 2GB ? Higher capacities can cause problems.

    - SD-Card-Format : FAT32 ?

    - All files and Folders with no special characters or fonts ?

    - Not too many folder levels, not too many folders nested within each other ?

    - All file extensions correctly ?

    - Test the SD card while the printer is not connected via USB to a computer.

    - Try a reformatting of the SD card to alternative devices.

    - Write-protect switch on the SD card may be faulty, test another card.

    - The gold contacts on the SD card could be contaminated or damaged, with a special fiberglass pen they can be cleaned. Alternatively and additionally, you can clean it with a Q -tip and medical alcohol (Isopropanol).

    I in your situation :

    - I would really check all the existing electrical connections again. Pull every little plug, inspect, and insert again.

    - After all this, a re- uploading the firmware, and or a factory reset might be the solution.

    By the way:

    So now I do not know if you have a UM1 or UM2. But the display of the UM2 flickers randomly, and just everything is unreadable, but that should not be a problem.

    Now I'm at the end ...

    The printer ONLY RECOGNIZES GCODE files.

    Not amf or stl. amf and stl files have to be processed using Cura to be converted to gcode:

    It only takes a few minutes actually, but if you take the wood cover off the ulticontroller you will see a small potentiometer in there. You have to pretty much take the whole thing apart. Turn that back and forth (while power is on) until the display is perfect.

    Oops, how could I not have seen that. Thus, the problem will be safe from the table. Gcode GGG-CODE and nothing else. :oops: So many words for such a small problem ... :???:

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
