[4.6.0] Unable to slice due to high print temperature


Recommended Posts

Posted · [4.6.0] Unable to slice due to high print temperature

When I set anything above 366°C for printing temperature, cura marks the input red and refuses to slice. This wasn't the case with older cura versions (e.g. 4.3.0). Is this intended or a bug? For me this is really critical since it prevents me from high-temp printing (or forces me to manually edit the gcode/use PP plugins).


I also recently had a talk with a high-temp printer manufacturer that told me they were about to switch from simplify3d to cura and this is one of the reasons why they still hesitate to make it their customers default slicer. I don't know about the other reasons though.

    Because most of the printers that Cura supports are marlin based (and marlin flat out refuses to accept higher temperatures). The change made here is indeed intentional. We recently did a security test and this was one of the remarks (eg; it could potentially be used to create files that cause very high temperatures, which can cause damage).

    Anyway, a machine definition file can change the maximum values, so the high-temp printer manufacterer can just set it to a higher value.

    What a bummer... but thanks for the answer. Do you by chance know what I have to edit in the machine definition to make cura accept higher temperatures for this custom printer?


    This is my definition file which I found in .../AppData/Roaming/cura/4.6/definition_changes (don't know if this is the right file in the right place; I believe not - but there's no file for this printer in Program Files\Ultimaker Cura 4.6\resources\definitions where I'd expect it to find)


    version = 4
    name = P220_settings
    definition = custom
    setting_version = 13
    type = definition_changes
    extruders_enabled_count = 1
    machine_depth = 150
    machine_end_gcode = 
    machine_gcode_flavor = RepRap (RepRap)
    machine_head_with_fans_polygon = [[-20, 10], [-20, 10], [10, -10], [-20, -10]]
    machine_heated_bed = True
    machine_height = 150
    machine_start_gcode = 
    machine_width = 205

    BTW, I found 2 other threads about the same topic which I'd like to reference here:




    I'm additionally also operating the Funmat which was mentioned in both of these threads, so for me this is an issue on two printers already. Also the suggested workaround doesn't work for me since I don't know where to put these additional lines (and there's no feedback from the affected user). I found the definition files wiki but nothing about changing max temps.


    It would be great if there was an option to define max temps in the machine setup GUI in cura.

      • 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.
