S5 flow rate & printing blobs in infill

Posted · S5 flow rate & printing blobs in infill

Two questions:

 

1: Is it normal that for almost every material (PLA, ToughPLA, ASA, ABS) the flow rate has to be changed from 100% to 95% in order to achieve decent layers? 

2: When printing with FilRight ASA Engineering filament, I tried using the quarter cubic infill. However, during the print, I can see 'blobs' of material showing up along the infill lines. See attached pictures. Am I printing too fast? I have attached the CURA profile that is currently in use for this print.

    This happens to me also with PLA and ABS prints on other printers. When your nozzle travels arroud some little amount of material can flow out and create this blobs. As far As I know it is nothing that affects the print qualité or the physical properties of your print.

    It is normal that you can see this in the infill, because infill is printed faster (normally) and there is no retract when traveling within infill, because it doesn't matter if there are strings or not.

    Hi

     

    The issue is not unique to the S5. The UM3's (and I suspect the 2 as well) also do the same thing. As long as you are using standard Cura profiles, you will get a bit of "extra" infill. This is the desired thing vs too little infill. As mentioned above, they can print faster if they do it this way.

      • 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
