Am I the only one non-symmetrical fan duct?


Recommended Posts

Posted · Am I the only one non-symmetrical fan duct?

I've been doing some mods to my UM2 recently (the low friction spool holder, the Olsson block and a new filament feeder) and so have spent quite a lot of time getting to know my printer and also looking around the forum in depth and I have noticed that my fan duct seems to look different to every other one I have found online. The left duct is bent further away. I'll try and attach a photo.

Is this as uncommon as it seems from looking around the web...and more importantly, is it a problem? I got the printer new in May 2015.

The second part to my question may render the first part unnecessary but I was wondering what the best way was to shift the airflow to suit the use of the Olsson block as I have already noticed that the cooling is not as good now I have the Olsson block on (much less tidy Ulti-bot!). I have found a couple of custom shrouds on YM like https://www.youmagine.com/designs/um2-olsson-block-fan-mountand THIS and also a simple extension HERE.

    The only problem I can imagine is if it's hitting the left side of the printer and maybe the airflow isn't ideal. Either way, it takes roughly 1.5 seconds to fix. The metal is very soft so you can very easily bend it down.

    Some people do have bent ones as they can bend easily, Mine looked like yours once after a print got knocked off and bent it.

    But as Robert says, Just bend it back.

    As for air flow. There are quite a few printable ones that work a lot better then the standard one. You just have to find one the you think will work the best ;)

    If you want to stick with the metal one though the simple extension bracket is a good way to go.

    Thank you both, and I wonder which one you would recommend Labern ;-)

    It was bent like that from new and I assumed that was by design since the nozzle is offset it seemed sensible that the shrouds would be different also. Having said that, when I took delivery of the printer, one of the guide rails was not clipped into the black runners so it had obviously had a knock at some point along the way. Anyway, after a little under 1.5 seconds of work, it is now just the same as everyone else's!

    And the next job will be print a new shroud. Thanks again.

      • 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.
