Which error was it exactly?  The errors all come with a web page you can jump to on the ultimaker website.  So look at the error more carefully next time and follow the advice (go to that web page and read everything carefully).

    • gr5 changed the title to Error

    Ah.  https://support.ultimaker.com/hc/en-us/articles/360015627259


    Yeah - that's the temp sensor.  The thinner 2 wires in the photos.  So this is never caused by a bad sensor.  They are made of platinum and will probably still be working thousands of years from now.  It's always in the wiring/connectors.  Usually at the print bed because it moves up and down.


    Do you or a friend have an ohm meter and know how to use it?  You want to remove the two smaller sensor wires under the printer and attach an ohm meter there (if the wires are connected to the printer that can throw off the reading.


    The bed should be around 109 ohms when at room temperature.  You can look up a PT100 temperature table to see what temp is what resistance.  all PT100 sensors use the same table.  All of them! Unlike other types of thermistors.


    So the white cables at the bed go into a connector.  I would take the bed completely apart (remove the 3 leveling screws and pay careful attention to how it all goes back together.  Then remove and reseat the wiring at the print bed.  Power up the machine with everything taken apart and check the temp of the bed.  then wiggle the bed around a bit, changing the angle of the wires and see if the temperature suddenly jumps away from room temp (around 20C).


    Anyway a common failure is the solder that connects the connector onto the build plate.  Or the wires just need to be removed and reinserted.  (at both ends of the cable).

    Hey I went through all the wires as written in Official site but its still crushes and throws out that Error. Can anybody tell or suggest what to do next or how to solve that problem? because it throws that after around 1,5 hours when printing

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
          • Thanks

      • 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 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.
