Slow as a rheumatic snail


Recommended Posts

Posted · Slow as a rheumatic snail

Can someone tell me why Cura is slow as a rheumatic snail??? It's really annoying that I have to wait 5-10 second or more when I change a setting. I like the SW otherwise, but this slow speed kills or the positive sides. Just can't understand. I have disabled the continuous slicing with that it was completely useless.

    It's very fast on most computers.  Even old, slow computers.  A lot of people complain that it is slow but most people find it just fine.  Try a different computer maybe?  


    It could be something to do with security (try turning off all security features for 10 mintues) or it might have something to do with the fact that it is always looking at drives (there was an older version of cura that was very slow if you had a certain kind of external drive plugged in - cura was trying to figure out if that was an SD card or something strange).  So check all your peripheral storage devices (and network devices) and see if dismounting them all helps.


    I'd just try a different computer.  It works great for me on both windows and linux.

    Perhaps if you tell us about your computer (OS, GPU), your Cura setup (what sort of printer, did you use the Custom FFF Printer or a predefined one?), and post your logs somewhere we can access then, we would be able to find out what is going on on your installation.

      • 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.
