ChangeAtZ

Moin,

 

Gibt es in Cura, oder mittels Plugin, eine Möglichkeit mehr Optionen in verschiedenen Z-Höhen zu ändern, als es das ChangeAtZ script zulässt? Konkret wäre ich gerne in der Lage die Wandstärke für einzelne Schichten zu verändern.

Die einzige Option die ich im Moment sehe, bzw. von der ich wüsste, wäre die gcode Datei selbst zu bearbeiten, zwei unterschiedlich geslicete Modelle zu machen und die Layer untereinander auszutauschen. Das ist aber schnell sehr viel Fummelarbeit, wenn man entsprechend hohe Modelle hat.

    Hello.

    There isn't really a way to affect the Z moves themselves.  Using "Adaptive Layers" will give you different layer heights in certain areas of a print.  They are calculated by Cura so you wouldn't really have any control.

    There is a setting for "Alternate Extra Wall" that will add a wall every other layer into order to trap the infill better.

    You can use a support blocker with the Per Model settings set to Modify Overlaps.  You could set the Wall Count to whatever you want.  I use that for extra material around holes that are for screw connections.

    This is with a thick support blocker configured to Modify Overlaps and as an Infill Mesh with 10 walls while the main model has 3 walls.  You can see that it adds an extra wall feature through the middle of the part although the model file does not have a wall there.

    Hey @FGoOse,


    Just curious.... Why would you like to change the thickness in the layers?
    Are you interested in time reduction or a strength increase?

    I think there might be other settings that can help you here. 

    If you share a file we can help to troubleshoot.

    Oh interesting.... It's more common to print sieves flat on the buildplate. 

    The people I've seen experimenting with sieves print something solid, remove the top and bottom and tune the infill settings to fit their needs. I believe this part is printed like that aswell

    If you still want to print it horizontally you can consider working with the mesh modifiers that @GregValiant suggested!
    You can also take a look at Infill Layer Thickness but you will probably need to change a lot like removing the walls and infill walls. 

     

    Good luck!

    What we have here is a model with 5mm thick plates at 5mm spacing that you can see off the build plate.

    On the build plate are two of them with one set at Z=-5 so it fills in the gaps off the first model.

    Model II has the Per Model "Wall Count" set to 0.

    This is it with the Infill turned off.  You can see that one model is just a shell around part of the model.  The other model has no walls and allows access to the "filter" which is the infill.  Neither model has tops or bottoms and so I used .8mm thick support blockers configured to Print as Part and with tops and bottoms.  They make the roof and the floor.

    Thanks for the replies. I think there is a little food for thought here and I will experiment with it.

    The problem is that I dont have straight models to work with. Copying and offsetting it wont work. I could however cut the model in fusion and prepare it that way. Might still be faster than to exchange layers in the finished gcode.

    If you have the option to alter the model in Fusion, I think that would be the best option. 
    Good luck! 💪

      • 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
