Cura speed problem?

Hi All,

 

I am using a up mini 2 with upstudio since some years and I just bought a bigger machine that I plan to run with Cura.

 

I launched some preview print to compare the two software and I am extremely surprised to see that for the exact same extrusion width and exact same print speed Cura is giving me a print time a lot longer than upstudio. I am really surprised and disapointed since upstudio time is real I don't understand why Print time would be longer with Cura ?

 

I also made the test with repetier host with Curaengine and the print time is close to the UPstudio even though the slicer is suppose to be the same.

 

Does anyone knows what is happening?  You can try yourselves by downloading Upstudio and repetier host and making the test with any part. Cura is always almost Twice longer for the same print parameters


Thanks for your opinion !

    I checked and Acceleration and Jerk have almost no impact on print time. The difference between UPstudio and Cura is twice the time so I think it's a more complicated problem.


    Does anyone knows what could happen ?

    I ran a test by printing a 100x100x100 mm cube empty with 0,2mm and 50mm/s and Cura gives me a print time of 1,27hours wich is more like 40mm/s.

     

    More of a problem, when I change print speed to 100 mm/s I still get 1h27minutes print time. Changing print speed had no impact on print time at all.

     

    Does anyone know what is wrong?

     

    Thanks !

    Thanks for your help. Actually With the cube there is only walls with 1 layer and it shows a clear "bug" from Cura with this profile.

    I don't know if it's possible to correct the profile to make it work good?

     

    It seems that whatever the printspeed I add in Cura it will print at 40 mm/s

      • 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
