Ultimaker 3: Filament not extruding?

Hi,

 

When I try to print I can see lines on the glass bed (really thin clear lines), almost no material at all comes out and the bed doesn't slowly move down as it continues. What could be the problem?

    Please give us more information, which print core, which filament, which settings. If you can upload the Cura project, it would also helpfully, because then we can see the object and all the settings you use.

     

    And, was the printer working before or have you unboxed the printer and this is your first print?

    Both printer cores print out like this.

     

    Printcore 1: PLA AA

     

    Printcore 2: PVA BB

     

    The cura projects are added, both printed out similar with just the lines as previously posted.

     

    The printer did work previously, it was run by some students of mine and they created a little robot and a boat.

    So you have loaded PLA material in Print Core 1 and PVA in Print Core 2, right?

    Your picture looks like you print the object with PVA and not PLA. Have you checked which extruder is selected in Cura for printing the object?

    I definitely made sure that I selected the correct materials for Core 1 and Core 2. I'll try again and reselect the materials to see if it repeats.

    You must also check which extruder should print the object like that:

    I never paid attention to this detail. Thanks! Hope this fixes it! Keep you posted.

    Just wanted to update and close the thread. One of our printers had to be unclogged, that was one thing. The other thing is that before we print anything (if we haven't just recently) we move the filament to make sure some of it comes out of the printer head first, then we print.

     

    In addition, we disabled the "automatic levelling" feature to never. We will manually do it once or twice a week, this held us up all the time and really the items come out pretty well without this double checking feature.

    Thanks a lot for the update and I am glad to hear that your problem is solved now.

      • 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.
