I would like to know hoe the flow sensor on the S5 is working. On my last print I knew I was running out of filament but let the printer running until it stops by itself to add more filament. Problem was that the printer had detect the lack of filament after it ran one or two layers. Adding the material did not save the print as it resumed at too far layer... Is this how it should work?

    Hi there,

    I got exactly the same question as I experience same behaviour. I have seen the printer working fine with the Ultimaker PLA and having the flow control enabled. But for third-party filament it doesn't seem to work as after few layers the printer pauses the job.

    I would really better understand if this can be fixed, as the printer is just awesome. Also the queuing of print jobs is excellent (just planned the next 24h :-)

    But.. if I run out of filament - thats bad.

    Help appreciated !

    Regards P.

    The sensor works fine for me with 3rd party filament and i use it all the time, printer is basically on 24/7 most the time.

     

    Have you updated to the latest firmware btw, i know a past update fixed a bug with the flow sensor saying one filament had run out all the time.

    That is strange and is not the way it normally works. I get perfect results when filament runs out, with UM and 3rd party materials, without any problems. So really check if you have the latest firmware.

     

    One thing you should keep in mind is, that it depends also on the time, how long is the printer waiting for the new filament, is important for a seamless result. If you change the filament in time then you see nearly nothing on the object. If you change it several hours later, you see that the layer is not 100%, but still acceptable.

    Hi there,

    Thanks for your feedback and suggestions.

    Just checked the version on the printer, it lists 5.1.8.20181207. Think this is the latest Firmware isn't it ?

    Primarily I was looking for if the flow control works for Ultimaker filament only. Based on your reactions, this doesn't seem to be the case (which is a good thing though).

    Firmware doesn't seem to be suspect (if it is really the latest one).

    One thing which comes to my mind is the screw on the feeder. I did not change the "pressure" on the filament. Just used it straight after unboxing.

    I'm down to the point now, where I would try to "increase" pressure on the filament in the feeder by adjusting the screw on the feeder (see attachement).

    But the printing results are anyways AWESOME!!

    Nevertheless I would appreciate the Flow Control feature :-)

     

    thx for your continued support

    Yes this is the latest firmware.

    The tension in the middle position is ok, you don't need to adjust it, only when you print with more flexible materials, but normally die middle position is more than enough.

     

    Maybe there is some dirt in the feeder? Just an idea....

    Possible.

    I'll check and will let you know.

    First I'll run some testing with genuine filament (incl nfc chip) on each extruder. Thereafter I'll open the feeder(s) for cleaning.

      • 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.
