Bed Spring Replacement (Ultimaker Original)


Recommended Posts

Posted · Bed Spring Replacement (Ultimaker Original)

I have an Ultimaker Original and the 4 bed springs seem to have lost much of their resistance. For example, when trying to raise my print bed, I cannot bring the bed closer than about 1 mm away from the nozzle because the springs don't have the strength to push the bed up higher. Loosening the screws is futile as the problem is the weak springs. I have also tried raising the bed via the z-axis adjuster at the bottom of the printer, but I've already maxed out the height and it hits the stopper.

Where can I purchase new springs? Someone mentioned D2150 springs are used in the ultimaker 2 and are superior. Will these fit an Ultimaker Original, if so where can I buy them?

    maybe you can adjust the position of the top z-limit switch at the back of the printer. Take a look at the build manual.

    Turn down the 4 screws on the build plate until they are in the middle of the spring and then manually raise the platform with the grey z-coupler on the bottom-inside of the printer until the nozzle just touches the build plate. Then loosen the z-limit switch on the back and slide that into a position that you can hear the click when it touches the wooden pin. After that you can fine tune with the 4 springs on the bed.

    Thanks for the reply, pics would be great. Why did you decide on washers instead of purchasing new springs? Were you also having difficulty sourcing a spring of appropriate size and tension?


    Thanks for replying, I tried moving the z-limit switch box, but the bed still contacts the switch above the point that the springs can extend. So ultimately the issue is with the springs not being strong enough to raise the bed high enough.

    here's a photo. I did not try to find new springs just because this worked and I'm lazy that way.

    I had tons of these washers, they are the kind used with pop-rivets. Two washers is what works well now. I started with 3 and that was too tight, one too loose.

    Great tip! I had the same problem with weak springs, and washers fixed it very nicely.

    In the long run, though, the springs will likely need to be replaced, so it would be good to have some advice on where to find them.

      • 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!

      • 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.
