'Shifted layers'-probleem bij nieuwe UO+

Posted · 'Shifted layers'-probleem bij nieuwe UO+

Dag allemaal,

Tijdens de schoolvakantie heb ik voor school een UO+ besteld en gemonteerd, maar op een kleine print na heb ik nog geen enkele behoorlijke print kunnen maken. Wanneer ik een object print dan gaat het aanvankelijk nog goed maar na enkele centimeters keurig printen schuiven de lagen behoorlijk heen en weer in de richting van de Y-as.

Ik heb de tips (o.a. van 3Dverkstan) bekeken en toegepast maar het probleem blijft.

- De pulleys nagekeken en goed vastgezet (met markeringen zodat ik verschuivingen kan zien)

- Nagekeken of de motor of de aandrijving ergens tegen sleept.

- Nagekeken of de assen een mooi vierkant vormen

- Een druppeltje machine olie op de X- en de Y-as.

Hebben jullie een idee wat er fout zit? Alvast bedankt!

    Na nog wat verder zoeken op het forum in het Engels kwam ik nog enkele gelijkaardige vragen tegen. Hetzelfde probleem, en toch leken ook daar alle mechanische delen (pulleys, assen, drijfriemen...) in orde.

    https://ultimaker.com/en/community/view/16487-shifted-layers

    Hier werd gesproken van oververhitting van de stepper-motor driver, de electronica dus onderaan. Een test lijkt dit te bevestigen, wanneer ik mijn UO+ op een verhoog zet en een ventilator heel de tijd voor afkoeling laat zorgen lukt het wel om een print van een viertal uur tot een goed einde te brengen.

    Voorlopig lijkt dit dus te helpen maar niet echt een bruikbare oplossing voor een klaslokaal.

      • 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.
