Printing is now rough


Recommended Posts

Posted (edited) · Printing is now rough

Apologies if this has been asked already - I am a relative newbie.

I was trying to print facemark holders for the NHS, but they fall apart.

 

With Ender3 Pro and Cura 4.2.1 with PLA my first prints were beautiful. Recently they have become rough and the layers don't seem to be sticking well (easy to break).

I am drowning in all the options. Have tried Super Quality and 60% infill but may have some other settings wrong, though I don't think I had changed them.

No idea if it is Cura or Ender problem (plate is level).

Suggestions?

    Please provide more information like pictures... It might caused by so many thing that is hard to say what's wrong for now.

    Yes, it will be far easier to identify whats wrong if a picture is sent. 

     

    I do believe from your description that it was under extrusion, but I cannot confirm it.

    Try to put a new nozzle

    As madman4 has said, you may get a new nozzle but since you stated that you are a relative newbie, it is probably a clog. 

     

    Try cleaning the inside of the nozzle or increase the flow rate for now. Decrease your printing speed to 35-45mm/s. Please let me know if you have any questions!

      • 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
