Is CURA supposed to reduce the file size of a part without any warning?

Posted · Is CURA supposed to reduce the file size of a part without any warning?

I just think that I have lost days of printing, a lot of material and a lot work time after I discovered that CURA, without any warning reduces the file size of a model when it is larger than 223x223x205mm that is the available print size of my Ultimaker 2+. The awful part is that sometimes it shows the real part size with gray stripes, making sure that the size is not correct. Some other times, and do not ask me why, the part shows colored yellow and fits the plate.

To make sure that I am not crazy, I drew a square solid prism that measures 243x243 x150mm and dropped inside CURA. It immediately accepted the solid showing the part colored yellow and stating its new size: 184.5x113.9x184.5. A reduction of 24,07%!!! Why? Without any warning?

I don't know what you think, but for me this is a really serious flaw and a bad behavior, because we cannot trust the information delivered by the software. The worst part is that sometimes CURA shows the real size of the part with its image grayed out in stripes.

Has anyone experimente something like this?

Am I doing something wrong?

thanks

Celso

    This Can be turned off in the settings under General, Scale Large Models.

    It should Warn you that the size was reduced. Well it used to.

    Thanks Labern. There should be a big warning stating "Model scaled to fit the printing are", or something like that. In my case, sometimes CURA scaled the big files, sometimes not, making me think that I was crazy.

    I also think that this feature should be off by default. If we want to increase or reduce the model size this should be done voluntarily.

    There Used To be that warning. Maybe there is a bug so its not displaying it.

    Not sure why it would slice sometimes and not others. It maybe a bug also or maybe the print was moved to the side a bit?

    Scale to fit is disabled by default. This was changed about 2 months ago, so this is in the 2.5 release

    Eehh...the current latest version is 2.4...so saying that this was changed 2 months ago is not true...maybe...depending on your release schedule...you could say that this will be changed in 2 months ;)

    Uh. Yes it is. I just looked at the commit that changed that line of code. The 2.4 release was in beta for a long time and someone fixed this on the master branch.

    Cura 2.4 still automatically scales large and small models...I just deleted my prefs and launched it again and those settings are enabled...so in the big world this is still an issue...until 2.5 is released. Whatever is changed in your development version does not count as fixed to the majority of the users ;)

    True, but you also said that it was changed two months ago...which is not true...since there is no Cura released with this function disabled by default...so this is not fixed yet ;)

    That said...i'm glad that Ultimaker finally came to your senses and realized that this was a very dangerous thing to have enabled by default :)

    The source is always released :) So run it from source and you have it seconds after it's committed.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
