Compare presets

Is the compare presets new?

Was added in 2.4alpha

It looks like it was added with the 2.4Alpha release. I don't see it in 2.3.3. Not sure if it was in Alpha 1, but it's in Alpha 2. 2.4 is a MAJOR update, lots of goodies.

Selective Brim with Modifiers

Is it possible to add a brim to a selective portion of a model with a modifier?

I saw I was able to add it to specific parts in a build but it applied to the whole part. Running in a production environment and anything I can do to reduce labor is a plus.

As you're printing loads of these part, why not disable brim and manually add it in just the places you want it. Obviously you need to set the height of the added material to whatever you first layer is set to.

Cad

I concur. It would be bette add partial brims in cad.

RE: PrusaSlicer 2.4.0-alpha3 is out

When I use that method the material doesn't "peel" off as easily as the brim. The brim creates the extrusions concentric to the model and maybe a little farther away to make it separate easier?

When printing hundreds of something any little reduction in clean up helps immensely.

What value do you have in "distance from object" in Print settings/Skirt and Brim?

Of course you can, here's the abridged version

Yes it is possible, however there is no button for it, it's a "technique" that starts in your 3D program of choice, and you will of course need a slightly better then average understanding of modifiers in slicer.

Copy/clone your model into the exact same coordinate space as the original, cut\ boolean  away the unwanted parts and import them into slicer together with the original, then using "split to Objects" and making sure the coordinates match up you can use the overlapping imported parts to set up your brims where & how you like using modifiers.

(This image shows 3 different brim Settings being used to secure a single model.)

I left the creatures front right foot Un-brimed for contrast, the front left foot is sporting a stylish 5mm brim with with a 0.1mm separation, while the rear right foot has an equally stylish but more petite fitting 2mm brim with no elephants foot compensation, and lastly the rear left with an oversized 8mm brim and a 1mm separation, for those days when you just want to let your claws breath.

Good Luck

Exactly what I was looking for

@swiss_cheese

That's exactly what I was looking for. Thank you so much for your help and those are some stylish brims.

I went with the 5mm, .1mm separation on the back feet only. Thought it gave him a ćhic look.

The only issue I ran in to was getting the coordinates correct and the models to overlap perfectly. When I exported the model into the modeling software to do the cutting and imported it back into the slicer it was slightly offset and had to eyeball it in with the move tool. I'll have to play around with it. Thanks again!

Clever Swiss

Oh that's clever. Much better than adding them manually cause you can play with the parameters of the brim on the fly rather than going back and forth to the CAD prog.

@adamade

It's unfortunate, but when you cut an object (using the Cut tool) in slicer<any version> the object coordinates get redistributed by what I'll call for the sake of this conversation, "center of volume". So the trick is to make & combine the parts in a 3d program, and import them all together, this will maintain their coordinate relationships.

As long as they are all touching the build surface they will not move when you apply "Split to Objects" once split to objects is applied you can select each part and apply the modifiers. You shouldn't need to reposition any of the parts if done correctly.

I should probably make a more detailed tutorial about this.

Good Luck, I hope this helps.

Correct, once again it's nondestructive.

Enjoy

That would be great.

@swiss_cheese

That's an easy enough work around and definitely makes it easier to accomplish.

Now I am trying to find  way to make instances of a part with the selective brim so I can load up the plate! 😅

M106 question

Hiho, is it normal for the slicer to add an M106 fan speed to every new layer? It means I cannot meaningfully change fan speed using the console. I don't remember this as an issue previously.

Many thanks.

It didnt do that before.  As to why its doing it now, I think that is a question that needs raising on github.  

@towlerg

Ok, I'll do it.

@adamade

You have two ways to go,

(1)

If your using windows, you will set up the model the way you want it, then Ctrl-A, Ctrl-C, Ctrl-V, (Apple is probably command something or another) you will have to manually place the copies since "Arrange" will separate the parts of each model assembly. This method is possibly less work depending on the complexity of the assembly and the number of modifiers. but you loose Absolute coordinate placement.

(2)

Import the model with all its parts, Don't "Split to Objects" at that time, create your instances Arrange them, then set them as separate objects and "Split to Objects". This method allows for rapid placement using Absolute coordinate placement, however you will have to setup each model individually. If using this method with the intention of using the same modifiers on each assembly I'd recommend copy and paste of the modifiers to speed things up.

You should be able to print Sequentially if that was the intention.

Good luck, let us know if you discover anything new.

RE: Supports

I am hoping the supports improve with the RC.  I still have trouble with supports sticking and causing poor quality under the overhang.  

Did you try turning Thick Bridges off?

BTW To whoever add the parameter search to PS, you are my hero. It makes it so easy to find obscure stuff and things that fall between two stools.
