underextrusion again & again & again

Posted · underextrusion again & again & again

hi all,

have been using by 5 month old ultimaker on and off whenever i could get time,

i have always come across under extrusion issues every once in a while.

i do not know wat i could be possibly doing wrong . i use the quicksetting and give a high quality print mostly but still i end up with issues,

i correct the tension of the feeder, i unclog the nozzle, i unwind the filament spool (so tat its easier for the feeder to feed the filament), i have opened the feedermechanism and havent found any irregularity in it.

i am really fed up ,

i hope i wasnt shipped out a defective ultimaker.

enclosed is the image , if anybody could help ,

a lot of my time is wasted in doing trial and error & i feel i constantly need to keep a check on my print every 15 mins , which is very annoying.

the only pysical damge issue that i could think of is that the pressure indicator broke once when myself & the local installation technician were trying to fix the under extrusion issue couple of months back..(but i always ensure that the screw is at the highest point)

please please help

    The tension of the feeder it's on the minimum position. Screw it so the indicator it's near the middle, that makes more tension on the filament grip.

    I don't even see the tension indicator sticking out.... take the cover of the feeder and put it back with the tension indicator sticking out..... it's the little notch on the part holding the spring.

    Then like neotko says screw it down till the indicator is half way.


    OK I'm not reading... it broke off... I would replace the part. Will only cost like a euro or so. Any reseller should be able to order it for you.

    And if ordering the part takes a long time you can just print one to bridge the time .... it's in the um2+ model on github. Just Google "github ultimaker 2+" you need software to translate the .step into an stl but many programs can do that... like the free "fusion360".

    You could insert some plastic on the top of the lever so it keeps making enough pressure.

    The oposite of this

      • 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.
