Posted · UM 2 ... first print..."sd card reading and then frozen"

Hi all,

Today I got 2 UM, over month waiting. Great!!!

 

But I was quickly disappointed.

 

When I wanted to make a first printing UM after calibration, the system display the message "reading SD cards ..." and nothing.

I tried use another sd card, reinstall the firmware, save a new print file through Cura. I still get only message 'reading sd card" and nothing more.

 

Does anyone have the same problem?

 

Best

Pavel

    Most of the problems with the SD card are fixed if you move the ribbon cables just a little bit. Remove the larger cover on the bottom of the UM2. There are 2 gray flat cables in the corner. Try moving them away from each other maybe and try leaving the cover off. See if that helps.

    So, I tried to move with both cables, pull out from connector and get back agin. Still same problem...only message "Reading card". Oppps.

    I do not like fold of the cable on the input exp1...look at pic.

    It is right that one of the cables (white, blue) is freely?

    That's normal. It is the same way on my machine. I think that is for if Ultimaker ever sells a "dual nozzle" upgrade. I think it will go to "temp2".

    To be on the safe side I put the cable professionally measure and is fine:-(.

    Bug is elsewhere.

    I believe the problem with the ribbon cables is usually "cross talk" where signals from one cable pass to the other as radio waves. So a meter won't show the problem. Try keeping the cables at least 10mm apart. Or just wait for Sander's new cable.

      • 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.
