How do you use an Modifier to change the layer thickness  

RE: How do you use an Modifier to change the layer thickness

PS does not support asymmetric layer heights within one model. Layer heights are only available for a full layer per model.

Not true.. You absolutely can... You can either user the variable layer height feature which has been in since day one (the button with a row of horizontal stripes, just to the left of the undo button).. or now you can use the "Height Range Modifier" (right click on the model and select "Height Range Modifier") feature where you can specify the bottom/top height and a new layer height. And you can do this as often as you want throughout the print.

And this works I use it all the time... But I wanted to do it using a "Modifier" as the Modifer function is called "Layers and Perimeters", but using this you can only change the "permimeters".... Hence my question.

PLEASE READ WHAT I WROTE.

Yes, you can change the layer height for specific layers. You can even do it individually for every object, but can't do it for specific parts (in the meaning of XY cutouts). For example, you can't change the layer height only for an arm of the model without affecting the rest.

Right.. I get you now.. I obviously understand you can't have different layer heights on the same layer.. Thats a limitation of FDM printing and I get that.. So sorry for misunderstanding you.

But thats not what I am asking... I want to use a Modifier to change the layer height ACROSS THE WHOLE MODEL.. Just because its easier to position than a "Height Range Modifier".. The Modifier type is "Layers and Perimeters" so I assumed it could be used to change the layer height too (like a Height Range Modifier).. Otherwise, why call it "Layers and Perimeters" and not just "Perimeters"?

RE: How do you use an Modifier to change the layer thickness

Ok, now we are talking. 😁

In PS we have the following:

• Global settings (profiles)
• Object settings
• Height range modifiers
• Object modifiers

You are looking for the object settings for layer height.

Look for your model in the object explorer (only visible in advanced mode or higher). In the column "Editing" there is a (box?) symbol. Click on it and choose either "Layers and Perimeters" (for most relevant settings) or "Add settings > Layers and Perimeters" (to only add layer height). This will add an entry to your object where you can change the layer height of the whole object. No Modifiers needed.

Cheers.. So almost the same as right clicking and adding "Height Range Modifier" which is what I use today..

Looking at the Edit box you mention, I can achieve the same there.. So I am god.

I just assumed we could use a "Modifier" since it has the option for type called "Layers and Perimeters".. But it seems that 'Layers....' part is is irrelevant as you can only change the perimeters..

I knew Modifiers were designed to be used "per object".. But I was trying change the layer height of a hiddent thread and was getting fed of of the trial and error approach I was taking having to typing the height as an integer.. So I figured by using a modifier that I could it to where I wanted  with the mouse might be easier to get to the right spot.

But its all good.. I can achieve what I want with the "Height Range Modifier" so will stick with that.

Thanks for your help

Its not layer thickness per model I was after. Its was layer thickness per height.

So basically I had a 100mm tall model which I was printing at 0.2mm.. And it had a number of "threads" which needed to be 0.1mm.. So I just needed a quick way to print these threads at a different layer height to the rest.

The "Height Range Modifier" does exactly what I wanted.. But I just wanted to select the area using the mouse by using a cylinder modifier, and I made a (incorrect) assumption that because the type said "layers and perimeters" you should be able to change the layer thickness instead.

So its fine.. Using "Height Range Modifier" does exactly what I want.

RE: How do you use an Modifier to change the layer thickness

Hi Guys, is it possible to add several height range modifier on an object ? I am using PS on a macosx. setting a first range ("Couches" in french) is fine but I do not find the trick to add another one !! Thanks in advance

RE: How do you use an Modifier to change the layer thickness

Yes.. there is a + button which lets you add another modifier.. i am not at my PC at the moment but will post something later..

RE: How do you use an Modifier to change the layer thickness

Here's what was supposed to go into this thread...

Somebody here on the forums pointed out the height range modifier to me. This was added to recent PrusaSlicer versions and is easier to use than the old approach. It's a little quirky, but works well. I think this is what @jweaver is referring to.

First, right-click on the edit button in the parts list:

Once you've added a modifier, you can add additional ranges:

The interface is a little clunky, but quite good for an early implementation of this feature. You do have to highlight the LAYERS selection in the parts list to enable the +/- buttons at the bottom to add subsequent layer height adjustments.

Thanks
Actualy the problem is with the french localized version of PS that I am using  !
I have switched in english and I can see the plus and minus 
This seems as a bug in localization : the length of the text strings is longer in french ...
Bye

You got it.. thats exactly what i was trying to describe. I also agree that the UI is a bit clunky, but there is no doubt its functional and works well.

I just so happened to have played with this yesterday but couldn't for the life of me remember how to add additional layer modifiers after the first. Had to poke around in the interface a bit to find it. Great feature though. Glad Team Prusa continues to add goodies for us.
