My work has damage at the shell

Hi @pizemakerstation, I am not sure which crack you are referring too but I will recommend to look into two features of Cura that would probably help. Apologies if I read your photos incorrectly. I would recommend to look into the Z-seam feature, and set it to random. The Z-seam forms when the print moves to the next layer and a small blob can form where the print head is while the bed moves down. Cura can hide this in a corner, but it can also scatter it randomly so it is less visual. 

 

For the 'scar' on the inside surface I would suggest to look into the comb feature, and set it to 'Not in skin' if it is not already (I think it isn't). 

 

Thanks, looking forward hearing from you if this made a difference!

Hi,

 

i also experience these "scars" on the outside. For me it's not happening when I'm using Ultimakers PVA, but a third party one which tends a lot to string.

I never really bothered with this problem, as it doesn't is a problem very often and when it's a problem, the printed part doesn't have to look nice.

 

But I'm assuming it is some kind of stringing of the PVA, maybe you could dry it and redo the print or maybe there is a setting in Cura which will prevent this.

 

Greetings

    Hi Everyone!

    I'm doing the same project with @pizemakerstation 

     

    Thanks for your recommendation! @SandervG @orlin278 @Framar  
     

    we'd like to give more detail about our problem.
    "some of PLA surface are indented. And this effect happens discontinuous "

     

    I was wondering.

    1. Is it possible for PVA to damage PLA While it's printing ?

    2. We're using the Material Station for a month.PVA was in there all the time. Average humidity is 15% > we don't think our PVA are moisture. Is there any problem that we're missing ?

    If you watch the print, you will see that it's likely that's due to the PLA starting to lift on parts where the overhang is almost flat, what could be a cooling factor or the PLA is just not sticking to the PVA very good.

      • 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
