Hi, so I'm having a problem with Cura 7.1 all of a sudden. It's that it somehow prints objects smaller than what it says it's going to be. I tested my machine to see if something is wrong with the firmware but it moves a solid 100mm when I tell it to through the USB connection using the laptop as a host.

 

This is the model:

 

Can it be that Cura is somehow producing a scaling error when generating the gcode? What kind of information can I share to find out what's the exact issue here?

 

Thanks for your time. My browser is tripping out after adding in a picture so I hope it's readable when I post this topic.

    what axis is the one that is the most problem?  x,y, or z?

    What is the expected size and measured size?

     

    How far off is it?

     

    Typically it's either off by a lot (2X) or a little (0.2mm).

    Okay, I am a bit ashamed. It turns out that my digital calipers are broken. I cannot reset it to zero anymore, causing all my measurements to be distorted and therefor the print being distorted and also me measuring the wrongly printed part with broken calipers. I just got out my analog calipers and apparently Cura is doing fine. Redesigned the part and now it prints in the correct ratio.

     

    Once again, sorry..

    Rapidly caught and well spotted, most wouldn't think to check their measurement tools 😄

     

    Don't be ashamed or apologetic and thank you for updating  your post so no one is chasing white rabbits.

      • 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
