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.

I basically want to change the wall count from 1 to 0 every 3 layers to get a sieve like structure.

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! 💪
