Rear shaft sticking out of UM2 case.

Posted · Rear shaft sticking out of UM2 case.

Received an Ultimaker 2 a couple of days ago and its printing very well, but I noticed that the rear shaft that drives the x axis is poking out of the left side of the printer a good 5mm. I noticed there is no bushing on this side between the pulleys and the bearing like the others. I looked up the build instructions and it seems that maybe there isn't supposed to be one? How should I adjust this? do I need to reset the pulleys and then tighten them down? also, and this is not related, the y axis rear belt is visably loose on the bottom, tops looks fine, should I worry about that? Thank you.

    I think a pulley must be loose.

    They should hold it in place, can you push it back and tighten the pulleys?

    If the slack is bad it could affect your print, but there is some room for play.

    Usually this happens when you pick up the Ultimaker and (accidentally) grab the belt instead of the frame. This can also be fixed by loosening the pulley's first, allow the tension to equally divide over top and bottom (maybe you need to help it a little bit), and then tighten the pulleys again.

    Let me know how it goes :)

    Great, thanks. It probably happened because we are in Thailand and it came here by way of Singapore, so thats a lot of travel.

    when I tighten the pulleys should the right side, with the nylon spacer be snug against the bearing or should there be some play there?

    just to be clear, these are two separate things, loose y axis belt, then the x axis rod loose.

    ill give it a try and see what happens.

    All pulleys should be tight against the wall of the printer.

    There's a spring inside the sliding blocks so if you loosen one pulley the pressure between the top and bottom part of the belt should equalize. Sander said you should loosen both pulleys but one should be enough really.

      • 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.
