Size does not fit

Hi.

We have a Ultimaker S5 and i did a calibration cube of 20x20x20.

The actual size is 20.2x20.2x19.5

Is there any options available to calibrate the E-Steps for correcting X and Y?

And how can i calibrate the z height? I see an elephant foot which i think is the problem for the z error of 0.5mm.

Thanks,

Andreas

    Keep in mind that the first layer will normally extruded with more material at default with Cura. For me mostly I reduce the percent value from 120% to 105% So I do not need to change any E-Steps to reduce elephant foot

    I wouldn't recommend to alter the Esteps. Since we work with a bowden tube I can imagine that the effects may not be immediately visible, and may even last longer than after your first layer and I think you don't want to add under extrusion to your print, right? If you have elephant feet I would first suggest to reduce initial horizontal expansion if your model allows it. Perhaps set it to -0,5mm

    Regarding other optimizations, can you try to adjust your profile accordingly:
    Line width:
    Make the line width equal to the nozzle diameter
    Speed settings:
    Equalise all print speed settings (i.e. infill, outer wall, inner wall, top/bottom) (good starting point would be 40mm/s)
    Jerk settings:
    Set all jerk settings (infill, outer wall, inner wall, top/bottom) to 20 mm/s

     

    Good luck!

      • 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
