Print order for multiple objects


Recommended Posts

Posted · Print order for multiple objects

Hello.

I ave 3 of the same item being printed, I assumed it would put down a layer or two of each object at a time to avoid collisions, but it seems my printer is attempting to complete the first model fully before starting on the next. Before I leave it running al night I fought I'd better check the behaviour. Will it lay down a certain amount before moving over?

Cheers.

    By default cura is in "one at a time" mode where it will complete one model at a time. This saves time as it's quicker (less movement of the head) and usually produces a nicer print. Another benefit is that if something goes wrong after 10 hours you may still get a few finished pieces instead of the whole thing being ruined.

    Nah, cura figures out which order to print and how far apart to place objects to avoid that. If you move an object close to another you'll see how it scoots the other out of the way.

    The nice thing about one-at-a-time mode is that if it fails half way through you still have half your parts completed and you can then just print the remaining parts.

    As long as the "gantry height" setting is correct (it is set correctly when you choose your machine on first start of Cura), then the printer should never collide with previously printed parts.

    It happened to me that a part came off the build plate and was knocked around the plate which messed things up quite a bit. That's why I won't print more than two or three pieces at a time anymore. But usually it shouldn't be a problem. Had I used a better technique to keep my parts sticking, I wouldn't have had that problem.

    That is very clever, I'll try it :)

      • 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.
