material 1 feeding stops

Posted · material 1 feeding stops

Someone please help me, so far I have lost atleast 11 3D prints and a big waste of time.


material 1 feeding stops and the print head runs without any material, and thus the print is incomplete. the reason is shown in attached picture, the tube comes out or material flow stops,......


so far I have taken different steps to solve this

1. initially there was Tough PLA Black when this problem first seen, thought tough black has some problem, so changed to PLA blue. but on the new print also , the same problem occurred

2. checked outer tube end portion, thought may be a bit worn out, so I did cut that portion. but problem still continued

3. did reset on factory settings of the machine, but problem still continued

4. did calibration of build plate/glass, but problem still continued

5. continually monitored material flow right from easy of spool rotation, to print head, everything seems normal but still the material feeding stops as the tube comes out as shown in picture.


the only thing happened since yesterday is now the feeding stops every 5 mins and things have got more worsen. Not sure what to do. Request your sincere guidance on this issue please @Smithy, @GregValiant, @SandervG, @gr5, @Philler, @RogueWave

    The reason is probably the connector part (collet) in the feeder, where you put the Bowden tube in. There are very small blades which should grab into the Bowden tube to avoid that it can slip out. In your case it seems that these blades don't grad deep enough into your Bowden tube and that's the reason why it slips out during printing.


    Contact your reseller to get a new collet, it is cheap and solves your problem.

    In the meantime you can try to cut of 3mm of the Bowden tube that the blades can grad into fresh material.

    And please don't mention users in every post just to get a faster response. We are also fast at replying and it is rude to mention masses of users. You will only achieve the opposite, so please do not do that in the future. Thank you.

    sure smithy will take care in future, and thank you for the response 

    actually this Monday (Today) we have sales people coming from all over the world, they come to visit the plant yearly once, and during their visit they also visit our prototype building shop wherein they would see me printing some 3D prints.

    that's the reason I was rushing to get answers from Ultimaker experts in last week. I just wanted everything to function normal during their visit. and hopefully it does happen

    Printing with PLA for a demonstration is a good thing.

    Ultimaker ABS and CPE would also be suitable for a safe demonstration. Both filaments have the property that they adhere well to the plate.
    Demonstration always sounds like a 100% solution. Hence the thought.


    Practically, you can also print temporarily with just the second printhead as an alternative.


    I and probably the others answer posts on occasion and in context.
    The exchange helps me keep my own production running and improve. I can recommend, because that saves time.


    Wish you good luck

      • 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.
