Non-solid solid bottom...

Hi,

 

I've been trying to print those fine cups of Joris. The walls come out perfectly but usually the cups won't hold water because the bottom is not solid. What could cause this?

    You are under-extruding, so the lines in the bottom don't match up properly. THis could be due to an incorrect filament diameter setting in your slicer. (e.g., using 2.89mm when your filament is really 2.8mm). It might also be due to printing very fast (which can induce a little slipping in the extruder). Or alternatively it could be due to using a Cura with a wall-width that isn't an exact multiple of your nozzle width settings.

    A work around might be to make the base thicker so there are more solid layers printed.

    What settings are you using? (Wall width, nozzle width, speed, temperature, layer height. Also, are you using the 'Joris' setting?

    Thanks for the tips. I tried to change the filament size and it got a little better, but it still seems that the lines are too far from each other in the bottom layers.

    Layer heigh 0.2, Wall thickness and bottom/top 0.8, print speed 50, temp 225, joris activated.

    I recommend some over-extrusion with 2.7mm filament thickness. And setting the "extra bottom wall thickness" to 15 in the expert settings also will help against leaking in the corners.

      • 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
