Cura not able to print High TEMPS? 390deg C


Recommended Posts

Posted · Cura not able to print High TEMPS? 390deg C


Am I missing something, I print high temp most days with another slicer but was keen to try Cura again.

Why does the Printing temperatures not let me set the nozzle temps above 350deg C??

also the bed temp tops out at 130 deg C.


I usually print at 415 and 145 bed on S3D slicer. No problem


Am I missing a setting here?

    Hello @jasontwd.

    @nallath explained the "why" here someplace.  As I recall he was forced to use "L" words like "Lawyers" and "Liability". 


    The Maximum Temperatures and their associated Warnings are defined in the "fdmprinter.def.json" file.  If you added the printer as a "Custom FFF" printer in Cura then it has those defined limits.


    If you were to create a custom definition file for the printer then you could add overrides to make adjustments to the Max Temperatures that your machine can handle.  There aren't that many 3D printers that SHOULD be allowed to go that high and prudence takes precedence.  I believe there are lot of Machine Definition files for certain printers that have overrides to set lower limits.  There may be one or two definitions that have higher limits.


    I don't think mom and dad would be pleased when their ten year old set their brand new "Cow-a-Bunga 3D Gold Pro Mini" to 2000°C because they read somewhere that they could print steel welding wire.  The house would not last long.

    A printer definition can say that they support higher temperatures, but they will need to do so. By default, Marlin (the most common used printer firmware) refuses to print at 365deg C. So that's what we set the default at.


    If your printer can do more, this is something you will have to change in the definition file.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • 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 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.
