Small layers at end of print


Recommended Posts

Posted (edited) · Small layers at end of print

When I have a print that finished with very little material per layer, the end often gets botched.


My hypothesis is that layers are printed on top of a layer that did not have time to solidify enough. Does that make sense?


Where is the Cura setting to prevent that from happening?

    I prefer to print a dummy "cooling-model" next to the real model. The dummy can be empty, except for the top which should have a less or more complementary print-area as your problem-area, so the total print time per layer stays almost equal. So the nozzle is moved away from the real model while printing the dummy, and the model has time to cool down. The advantage of the dummy is that the print speed and material flow stay constant, and thus the temperature and viscosity of the molten plastic. Disadvantage is that is wastes some filament.


    See the pics below. The first pic shows the problem: the hot nozzle staying on top of the cones, and preventing cooling and solidifying. The second pic shows a hollow dummy (except its top), used in a real design.

      • 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
